One of the most common questions I receive from people who have become electrically sensitive is “How can I use a computer without increasing my symptoms?”
Some people experience headaches, brain fog, rashes, burning skin, heart arrhythmia or other electrical sensitivity symptoms when using a computer. Whether you already experience symptoms or simply want to use a computer in a healthier way, there are a number of practical things you can do to lower your EMF exposure.
Computing has been a struggle for me since becoming electrically sensitive over a decade ago. I can have periods of high sensitivity that last for for weeks. During these times, being on a computer just 30 minutes a day can be a challenge.
However, through this process I have learned a lot about what works, and what does not when it comes to using a computer safely. I have become much more resilient because of this and now have long periods of time with no symptoms at all. My hope is that you can implement some of the following solutions to get back online or to simply prevent you and your family from experiencing the negative effects of EMFs.
My Top Low-EMF Computing Solutions:
1.) Utilize the basic steps for safe computing. These are steps that you can use – even if you are not electrically sensitive. Read this article to learn a few quick modifications to your computer setup.
2.) Heightened EMF sensitivity may come and go. As I mention above, I have had times when I could not tolerate using a computer. These times can be very discouraging. However, after some time, my symptoms would lessen and I could get back on the same machine that previously gave me intense headaches and/or heart palpitations. Overexposure will lead to downtime.
Learn to pace yourself. You may be able to do 20 minutes per day and then work up to a couple hours or more per day. I can now be on my laptops 5-6 hours per day. When you start to get a tension headache or that buzzing feeling in the head, back away and take a break for an hour or so. Taking a shower, running cold water on your hands and face or going for a walk in nature will help reduce the symptoms.
Use Less Powerful Devices:
3.) Try an electronic keyboard. During times when your symptoms are intense, there are still ways to be productive. I typed this article on my AlphaSmart 3000. It is a battery powered electronic keyboard (with almost no EMFs!) that will allow you to type up to 100 pages that you can easily import into a computer.
It’s amazing how productive and creative you can be without the distraction of the internet right in front of you! Many writers use these for their first drafts. Most of the material on this website was written on my AlphaSmart 3000 (pictured below). I recommend that you purchase the AlphaSmart Neo or Neo 2, which are newer models than the 3000 that I have. You can find a high quality model on ebay for about $50. It is one of my favorite low EMF computing purchases and it will last you for years.
Your office can be anywhere with an AlphaSmart.
4.) Use your smart phone for communicating. This may sound antithetical to some, but hear me out. I have multiple EHS friends who have figured out that the least painful way for them to be connected to the world is through their smart phone. With the phone on Airplane mode, it is actually a very low EMF computer. You can type responses to your messages and then press “send” while the phone is on Airplane mode. The messages will be stored in the phone. Then, put the phone down on a table, turn off Airplane mode and walk away from the phone. Within 30 seconds, the phone will have sent all stored messages and downloaded any new messages.
Other than a couple seconds of exposure after turning off Airplane mode (you could also have your spouse or a friend do this), this method is nearly EMF free and is a good option for those who need to stay connected for work or family reasons. The phone need not be off of Airplane mode more than 5 minutes a day, depending on how many times you need to check and send messages.
Note that this method works for text messages, WhatsApp and most web based email like Gmail or Yahoo. It does not work for certain apps like Facebook Messenger or Google Hangout. This method works incredibly well for those who are too sensitized to EMFs to safely be on a computer. See #9 below for another tip on using a phone.
How to Find a Low-EMF Laptop:
5.) Not all computers are created equal. The severity of your symptoms may depend upon which computer you are using. I find that older systems with less processing power are easier to use without electrical sensitivity symptoms. There is something about the newer, more powerful computer processors and screens that give me a headache and chest pain very quickly.
I have purposely tested many computers the past few years to see what works and what does not. The following is what I have found to work for me. Please note: We are all different and an electronic device that works for me may not work for you. However, in speaking to others who have experimented with various computer models and brands, the following is generally true for many people who are electrically sensitive. If you use other models successfully, please share the model below in the comments.
My Recommended Low-EMF Laptops (August 2023):
Toshiba Satellite Laptop (Purchased 2015 & 2018 – exact model number is C55-B5298 with a Celeron processor). This computer has minimal computing power, but works great for my writing and basic internet use (pictured at right). You will have to shop around to find an available unit to purchase (they sometimes come up on ebay, Walmart or Amazon). You will search for “Toshiba Satellite C55-B5298 15.6″ Celeron N2830 2.16Ghz 4GB 500GB Win10”.- Dell Latitude E6230 (Purchased this computer in 2016, 2018 & 2019 with this model). This small laptop computer has excellent computing power/speed, but is also very quiet and gives me minimal symptoms if I use it for only 2-3 hours at a time. It’s my primary laptop for Zoom calls and internet use. You will have to shop around to find an excellent condition model for purchase. They are typically available here on ebay, Walmart and Amazon. You can do an internet search for “Dell Latitude E6230 12.5″ 8GB RAM SSD i5-3320M 2.6GHz Webcam”.
- Toshiba Chromebook 2 (Recommendation from client 2023) This is a very quiet, low-EMF machine that works well for electrically sensitive people that don’t mind using a Chromebook (not Windows or Mac). This specific model was manufactured in 2016. You will search using these details: “Toshiba CB35-B3340 Chromebook 2 Part Number PLM02U – 009008”. Here is one currently on Amazon.
- Dell Latitude E6330 (Recommendation from a client in 2022) – This Dell laptop is very similar to the E6230 that I have been using successfully for the past 10 years. This one appears to be easier to find used at this time on Amazon and ebay and is working well for several clients of mine. If you try this model, please leave a comment below to let us know your experience. Search for “Dell Latitude E6330 13″ Laptop Intel Core i5-3320M 2.6GHz 8GB 320GB Windows 10 Webcam”.
- Acer Aspire V5 11.6″ Laptop (Purchased multiple units in 2019). Small, lightweight, good speed. This laptop works very well for me. It’s an easy laptop to take to cafes to do some writing. I have the 4GB Ram model and moved it to Windows 10 for better performance. You can find this version on ebay here. Search for “Acer Aspire V5-131 11.6″ Laptop”
- Lenovo Chromebook (2022) – Over the past year I have purchased and tested several Acer Chromebooks (2013 and 2015 models). These simple machines are great for electrically sensitive people. However, due to their age, they are no longer updated. Several of my clients have instead purchased this Lenovo Chromebook, which you can purchase new on Amazon. If you don’t mind the limitations of a Chromebook (no MS Office applications and you must use the Google systems), these can be excellent, simple computers that cover most of your internet needs.
- Many desktop computers (or laptops connected to a docking station) with separate monitors can also work well (Older Dell monitors worked best for me). You can also use a screen magnifier so that you can sit farther back from the monitors. Desktop systems provide the ability to modify your work station in a way that lowers your EMF exposure (like moving the computer and screen farther away from your body). Several of my clients have done well with the Dell OptiPlex Desktop. Search for “Intel Core i5 – 8GB Memory – 500GB Hard Drive.”
How to Find Low-EMF Laptop Computers:
For any used/renewed laptop purchases of the above models on Amazon or Ebay, just make sure you can return them within 14 or 30 days if it doesn’t work for you or if the machine is not working properly. I often buy a few models at a time and keep the one that works best for me. I typically take these older machines to a local computer repair person who keeps them running smoothly and updates any hardware/software that is necessary. Some laptops will last 10-15 years if you treat them well and a solid relationship with a good computer repair technician in your community will help you to have a low-EMF computer system for years to come.
As I always use my laptop on battery power, it is recommended that you buy a new battery whenever you purchase a used laptop. This will give you 3-4 hours of use before having to charge your laptop. As you can see in the picture below, I often have multiple laptops of the same make and extra batteries, which will allow me to keep working without having to wait to charge the laptop.
For the Dell Latitude E6230, I call up Dell directly and order a long-life OEM battery that is made for the laptop. These batteries seem last longer and are more durable than off-label batteries. The battery for this laptop is the 58 or 65 Watt Hour VMware 6 Core Processor, 3YRW.
The part numbers are Y61CV and FN3PT for these long-life Dell batteries. I have paid anywhere from $25 to $140 for the batteries directly from Dell. If Dell no longer carries a battery for your laptop model, you can find a replacement battery through Laptop Battery Express.
Laptop Models and Brands that are Typically High EMF:
The following are computers that I have reacted to very quickly (usually headaches and pressure in the chest within 20 minutes to an hour of use). I returned these computers within their 14 day to 30 day return window and moved on.
- MacBook Air Laptop (Purchased and returned 2012)
- MacBook Laptop (Used 2013)
- iMac Desktop (Used 2014)
- Dell Inspirion 15 (Purchased and returned in 2014)
- Dell Inspirion 15 3000 Series (Purchased and returned 2015)
- HP Pavillion Laptop (Purchased 2013)
As a general rule, older corporate Dell laptops and new Toshiba laptops (now called Dynabook) seem to work well for electrically sensitive people. Anything from Apple, along with HP’s and the newer Dell laptops tend to be high EMF machines. I have heard from many EHS people that Apple computers are the worst for them (partly due to their aluminum case – see this video). It’s a shame because I really like Apple computer systems.
Additional Ideas to Make Your Computing Healthier:
6.) Rotate Your Computers. If you happen to have a couple different computers (possibly one old computer and one new), it helps to limit the amount of time you spend on any one of them. I find that if I start reacting to one computer, it is best to not use it for a day or two. I usually cycle between 2-3 different laptops listed above and pictured below. Every computer emits its own set of frequencies. Changing things often prevents your body from becoming sensitized to any one computer.
The Low-EMF Laptops that I use throughout the week.
7.) Work in a low-EMF environment. You could have an ultra-low EMF computer, but if you are in a high EMF environment you may quickly develop symptoms. Here is a summary of how to measure and reduce the four types of EMFs in your home and/or work space. Here is short video that show you how to measure your home. Finally, the following image shows the EMF measurements at my current laptop workstation. The RF, magnetic and electric field components are all very low. You can learn more about these meters and how to use them on my EMF meter page.
How to Find a Low-EMF Keyboard and Mouse:
8.) Use a Low-EMF wired keyboard. Not every wired keyboard (or mouse) is low-EMF. Some will have cheap circuitry that will produce significant amounts of EMI (electromagnetic interference). This can be a problem for electrically sensitive individuals. I test my equipment with a Radio Shack AM radio model 12-467 (you can typically find one on ebay) or this TECSUN shortwave radio on Amazon. Here is a short video where I demonstrate how you can test your keyboard. This wired keyboard has been tested to be low-EMI. I currently use this basic wired Microsoft keyboard and mouse.
9.) Wire Your Smart Phone. An electrically sensitive colleague recently shared how she uses her smart phone for emails. This helps when she is going through a time of heightened sensitivity. Below you can see her Samsung S3 that is connected to an external keyboard and mouse. The mouse cursor actually shows up and the smartphone then acts like a small computer screen. This is often better than a normal computer screen for ES people. She is able to compose her emails and do her writing on Airplane Mode.
The messages then send once the phone is reconnected to the 3G/4G network (she steps away from the phone then). The USB attachment seen below can be found here. As outlined in this article, it is also possible to connect most smart phones to the internet via Ethernet, which makes it possible to use your device without any wireless connectivity. This is truly a low-EMF computing solution.
How to Build Your Own Low-EMF Computer System:
10.) Build your own system. For some individuals, using a computer in a normal manner may become too difficult. The good news is that even in this scenario you can still work, be online and stay connected to the world. It will take some technical knowledge and added expense, but it is completely worth it if you need to be on a computer for your income.
The following is one such system designed by Bruce McCreary, a retired electrical engineer who has been electrically sensitive for nearly 30 years. It took him considerable time to design and build this system. However, he now has an ultra-low EMF computer setup.
This system has a specially designed keyboard and mouse that have almost no electric fields. They are connected to a computer that is in a specially shielded box that is typically in another room. For the computer screen, a small LED/DLP projector behind the rear projection screen is set to rear projection mode and projects towards the user onto the screen.
Here are some images of Bruce’s computer system that he designed for his off-the-grid home in Arizona.
The computer screen above is actually from a projector behind the wall.
The projector is in a shielded box and sends the images through an inverted lens.
Most of the high-EMF computing components are outside this home.
Hopefully these suggestions will get you back in action and keep you healthy for years to come. If you know someone who cannot be on the computer to read this article (very common for EHS people), please print it and mail it to them.
If you have any suggestions of low EMF computers or methods that have helped you, I would appreciate hearing about them. Please share your ideas below to benefit others who are experiencing the exact same thing.

jeromy, great list! i want to add two computers to the “low emf” computer list.
1. asus eee pc 1005 series 1005HA (it’s a netbook). works well for little tasks like word processing. not so great if you need to have multiple applications open at once.
2. acer chromebook. i love my chromebook. it’s fairly affordable, lightweight and best of all- it feels like lower emf to me. you do need wifi access to use it though.
i do have a question about the airplane mode suggestion. if you have a smartphone on airplane mode, doesn’t that mean you can’t send or receive phone calls or text messages?
i’ve had such bad emf from iphones in the past, i am hesitant to get one. instead, i bring my acer chromebook with me everywhere. if i need to figure out something, i stop at a starbucks or mcdonalds, use their free wifi for a few minutes and then get back on the road.
that alphasmart neo looks awesome. i’m gonna check that out for sure!
thanks jeromy!
Jeromy
Hi Sara,
Indeed, if the phone is on airplane mode, then no messages can be received or sent. The phone is not transmitting, so it becomes a little computer that cannot communicate in that mode.
Many of my friends have said the same things about iPhones. They would get headaches quicker than with other phones and sometimes could not even hold the phones for any length of time. For some reason, Apple has made their products to be very powerful emitters of microwave radiation.
Thanks for sharing your suggestions and experience!
Jeromy
Patrick Smith
If you are EMF sensitive then you would never use computer WiFi and be around a router. Just saying.
Janice Block
If you need wifi to access the acer chromebook, why say it’s great? For what??? Not for anyone electrosensitive!
I can’t be in a house that has wifi, let alone work on device with it. In that case, my MacBook Air with an ethernet connection is better than the acer chromebook.
Jeromy
Hi Janice,
You simply use an Ethernet to USB adapter with the Chromebooks. No WiFi needed.
MacBook Pro’s and MacBook Air’s are some of the worst as their metal cases radiate the electric fields and EMI that come to them via the Ethernet to Thunderbolt connection.
I wish I could use Apple laptops, but, alas, most ES people cannot.
Jeromy
Jennifer
A lot of Samsung’s are low EMF.
Nancy Baer
Thank you for this informative article and for mentioning that you’ve noticed that your sensitivity seems to be intermittent because I have noticed the very same thing and thought that it meant that those of us who are sensitive are sensitive to different electronic sources. For instance, I have a sensitivity (and an attraction) to mostly compressors located in buildings. I traced this back to my childhood to having my ears x-rayed to treat my chronic middle ear infections and laying on a cold x-ray table with this enormous machine hanging from the ceiling, pointed toward my ear and head, and hearing that low whirring sound. Recently, while I was out and about getting a haircut located close to an enormous cell tower, I could not put the words together in a sentence. As soon as I left the shop, I was fine. I explained to the hair stylist the next time I saw him what had happened to me, but I know he didn’t understand it.
mo lohaus
Hi Jeromy,
I appreciate this article, particularly the strategy about using a smartphone. I often work with a similar solution, adding functionality by using an external keyboard and charging passthru adapter to keep the phone (or in my case iPod touch) fully charged.
I use a Macally iKey30 wired keyboard with a Cable Jive Dock Stubz plus passthrough adapter and an Apple 30 pin to Lightning adapter with an iPod Touch 6th generation (roughly the same as an iPhone 6). No problems at all.
More importantly however, though extremely sensitive to EMF, I am able to compute freely using an Earthing desk pad in front of my keyboard, and even tolerate wifi and cellular better when grounded by the forearms. The radiation is literally grounded to the earth and my nervous system remains at ease. The laptop or desktop I use is largely irrelevant with this setup (I use a PowerMac with a really big processor, a MacBook Pro and a Toshiba Chromebook–and yes the Chromebook is very EMF quiet–and none of them affect me when I am earthed. The only computer I could not use was a Dell Inspiron 10″ Hackintosh with a 32 gig SSD drive (it came with 8 or 16GB standard)– something about that bigger drive made the computer hot and the EMF unbearable.
Thank you for your good work, helping us function in this world.
love
Mo
Kirby
Mo Not sure if you will see this, but what type of Earthing desk pad did you purchase and do you have one for your mouse as well?
Antoinette Fiumos
Could you share where you purchased your Earthing pad?
Jeromy
Dear Antoinette,
I would read this before you start using things like Earthing pads:

My best,

Great article. A few other things that have worked for us:
If your computer plug does not have a ground prong on it, you can buy a $7 cord that is a USB plug on one end and a 3-prong plug on the other, but with only the ground prong “active.” It dropped the electrical field SIGNIFICANTLY at my husband’s laptop.
In the “cell” settings on your smartphone, turn OFF “Enable LTE”. That will only allow your phone to communicate on the 3G network. My iPhone 6+ puts out 6 times as much RF on the LTE than on the 3G, and on 3G it falls off MUCH faster.
Use a wired keyboard on your computer. My legs were swelling painfully for 2 years before I figured out it was my wireless keyboard.
Only use your computer over hard-wired Ethernet, and turn off the wireless on your router and/or modem and turn it off on your computer and phone.
Rebecca
In the UK, BT (British Telecom) are using their home routers to transmit public wifi as standard. I discovered this only when, having switched off our wifi and ethernet-cabled our computer, we had our home surveyed for EMFs, geomagnetic stress etc. and realised the router was still emitting wifi – just not for us to access but for anyone passing by! They do this to save paying to use mobile mast transmitters. So it’s important to check that your router isn’t set up the same way. It is possible to opt out if you know how to via your internet provider. It can take BT up to 28 days to actually switch off public wifi (BT Fon, BT Openzone, BT Wifi with Fon) once requested as it is dependant on a once-per-month visit to the exchange.
mark w
I’m pretty sure you can thank Comcast for that. Here in the States they’ve gone crazy, even saying that they are going to remove the functions to opt out. Leaving the only option buying your own hardware.
And on a side note, you can use an iPad or iPhone with lightning and USB adapter with some** USB Ethernet adapters! I have tried this and it does work on 1 out of 2 of my adapters, but in my case I had to use a powered USB hub.
Rebecca
I’m finding that it takes so long to do anything on my smartphone on 3G that I spend more time hovering over it waiting to see if it’s doing anything than if I could just dip in with a faster signal, put it at a safe distance, check it and walk away. But then, I’m talking mostly for uploading/downloading. I guess your suggestion is for a general setting so you’re reducing emissions whilst on standby and using it for calls etc? I just keep mine on flight mode except when I want to use it or check it.
Bill Bruno
Thanks for these ideas. I would also add that I used a Raspberry Pi model B for over a year and had very little reaction to it. The problem is you need a monitor to go with it, and my monitor died. The original model B had a linear voltage converter. The newer Raspberry Pi’s have a switching converters which may be problematic. Also, the model B did emit measurable RF when the ethernet jack was in use. Simply unplugging the cable eliminates that. Staying 10 feet from the computer and ethernet worked for me. You still need a good keyboard and mouse to go with it….
Bill Bruno
I forgot to mention that of course to benefit from the low EMFs of the Raspberry Pi you have to run it from some kind of battery or from a good linear power supply. I got a 5V wall wart and spliced on the necessary mini USB plug.
Connie
Is there a way of running a Raspberry Pi on a battery? If there is, it’s probably done with a DIY approach, I imagine.
Thanks,
Connie
Jk
I don’t think you mentioned using the device while it’s not charging. My Surface RT made my face burn. I got glasses so that I wasn’t putting my face so close but also found it was only a problem if I used it plugged-in and charging. Now I charge then unplug before using.
Jeromy
You are exactly right JK. I hardly ever use a device that is plugged in. I mention some of the basic steps, like working off of battery power, in item #1:
https://www.emfanalysis.com/safe-computing/
Thanks for pointing this out.
Jeromy
Kumara Bhikkhu
Working off battery power is the best, but that’s not always suitable. The next best thing is have the computer plugged in *without* the battery. Plus, place the power adapter furthest away. I can work for hours like this without much negative effect.
Elizabeth Foley
What if the laptop is on battery, but is then connected to a larger screen which itself has to be plugged in? The larger screen allows me to sit further away from the entire laptop (about 6 feet away), and still see what I’m doing. This has helped my brain fog while working, but my hands are still burning badly from using the wired keyboard and wired mouse. The mouse is burning my palm even though it’s an old school roller ball with an adapter to plug into the laptop. Is the plugged-in screen maybe bringing EMI from the grid and then the EMI is getting onto the keyboard and mouse?
Jeromy
Hi Elizabeth,
Yes, that’s exactly what is happening.
Have you measured the EMI with an AM radio and the electric fields with a grounded ME3830B/ME3851A?
I recommend a TECSUN shortwave radio to measure different bands of EMI frequencies. The MW band is similar to AM. You can find this here: https://amzn.to/3jqPlPt
Here are the ME3830B / ME3851A. You get a 10% discount with SLT with my code of EMFA:

Walt McGinnis
Jeromy,
Good work…
How did you do the testing. I do three tests. 1) Ac magnetic fields—Trifield meter is adequate. 2) electric fields –Gigahertz solutions meter 3) radio frequency radiation Gigahertz solutions meter.
Sometimes instead of saying absolutely, this is safe and this is not, I apply a subjective risk assessment. Low Medium high Very High Extreme.
The electronic keyboard sounds like a great idea. Folks can wander around with it.
Might be good to mention that all the computers are hard wired.
I use a laptop with a separately wired keyboard and separately wired mouse and a second larger screen.
Limiting wireless use is a key strategy for me.
Less is always better. Sometimes there is damage to the nerves at the brain stem. This can be healed with a little time spent away from the radiation. For severe cases, ie, when folks they are not sleeping well and/or hearing noises at night, ultra sensitive hearing. I recommend a 3 month holiday from wireless technology and then maybe if symptoms are lessened a reintroduction of the technology at lowered exposure levels. Sometimes we just have to give it all up for a while to get our health back.
Best,
Walt McGinnis -mcginniselectric.ca registered in BC Canada 14318 FSR 33661 RB
Jeromy
Excellent suggestions Walt.
I use similar meters to do my tests – plus my body, which is the most sensitive measurement device of all. . .
I can also relate to your prescription for lessening the symptoms. Time in a good environment will typically do wonders. I no longer use any wireless though and I encourage others to go toward wired computing if at all possible.
Jeromy
Steve
Brilliant article Jeromy. So helpful and informative. Your site is a great reference and it all comes from first hand experience. I’ll be recommending it to many people for years to come.
Jeromy
Thank you Steve!

Here is a bit of recent feedback. While trying to replace my old computer, the first attempt, the Lenovo Yoga 3 (solid state) didn’t bother me much but it was a horrible computer. It had many bugs with Windows 10, don’t try it until it has been sufficiently debugged. I got this Dell 7000 series with solid state and it does seem to bother me… will probably have to return it.
My computer guy understands my EHS and says that it doesn’t seem too hard to build one.. That is the good news.
Bill Bruno
Usually people who say it’s not hard to build a low EMF computer don’t know how hard it really is. But maybe you’ve found someone who can? It’s hard to even find a good power supply, although a standard linear one if far away is OK. Most attempts to shield the box don’t work because you need to filter all the cables. RF enclosures are pretty expensive… the cheapest I know are the Hoffman RFI models, and they quickly run into money as they get larger. Luckily the Raspberry Pi is quite small, if it’s got enough power for you. There are other small computers that work on 12V batteries that may be a good start for some…
Yash Rungta
a few more tips that I use for computers to protect myself:
1) I use wired keyboard and mouse. Mouse should be non-optical.
2) I reduce the brightness and contrast to its lowest to soothe my eyes.
I will look for a new laptop and mostly go for one from your article.
Leanora
I just wanted to give you a heads up on a great book … discussing all the research on RF, LF EMF’s and also Dirty electricity and what is being found. DE is probably the worst culprint and the key cause of cancer…
The book is excellent source of great information, references, and science studies… Call Light That Heals, by Donna Fisher.
Thanks for what you do, I just felt this information might add even more value to what you do.
I am probably going to have to undertake filters to keep my environment clean of dirty electricity.
Blessings, Leanora
Jo James
Dear Jeromy,
Thank you for your helpful EMF information, that I’ve forwarded to several contacts.
Six weeks ago I replaced my 6-year-old, no-EMF-reaction white MacBook with a MacBook Air. Fortunately I’ve been able to reduce my ensuing headaches, chest discomfort and other reactions.
I would appreciate knowing asap how to import draft text from an AlphaSmart 3000 Neo into a MacBook Air. Also, could you recommend any reliable source(s) for a Neo on eBay?
Finally, I’m considering replacing my Epson Stylus C88 printer. Could you recommend, at your convenience, a few low EMF, preferably compact all-in-one, inkjet printers that hopefully are available in Orange County CA stores?
Many thanks for your help.
Jo James
Jeromy
Hi Jo,
I had the same reaction to a Macbook Air. I thought it would work great, but I reacted to it almost right away. Good that you have learned to manage it.
The Neo will integrate with any computer that has a USB port. You just need to have a program like Word open and then the Neo will automatically type what you have written into the Word document. You can then do what you need to with the document on your computer.
In item #3 above, I link to a Neo on eBay. I bought one through this seller (to have a backup) and it works great.
Finally, I can’t really recommend any specific printers. I doubt they matter that much from an EMF perspective because we they don’t need to be turned on that much. I had an HP 6500 series which worked fine. Do make sure to disable the wireless function of any printer. It’s amazing how strong the wireless antenna is in most printers.
Thanks,
Jeromy
Laura
Do you recommend your MacBook air?
Jeromy
Hi Laura,
No, I don’t recommend one. I returned the MacBook Air that I bought a week after purchasing it (after reacting to it so quickly).
So many ES people have a difficult time with Apple computers. Could be the processors or screens or a combo of both.
Read section #5 above for the laptops that have worked okay for me (and others).
Jeromy
Theresa
Sadly, I wish I had read this blog before purchasing my MacBook Air – I have indeed reacted immediately with major heart palpitations and headaches. Still in the grace period so returning it. Thanks for all the great info.
Theresa
Judy
In response to Theresa – MacBook Air is 10watt TDP (i gather), whereas 1.6ghz eee pc’s seem to be 8.5watt. So the key point seems to be GHz.
..though what confuses me, is that dual-core can also be as low as 1.6ghz.
Perhaps Jeromy can shed light as to whether some dual-core’s can actually be tolerable, as long as they’re 1.6ghz?
Mary Anne Tierney
Jeromy,
This is an AWESOME article! You continue to amaze me…how you have made sense of suffering by helping others avoid it.
Regarding the Router Guard, which seems like a great gift we can give to neighbors who can’t / won’t get wired up: Do you think this guard sold by LessEMF would work for schools’ “access points”? Seems like there is a market for such a gadget, given routers in nearly every classroom.
Warmly, Mary Anne

Thanks Mary Anne! Indeed, hopefully this site will help many others avoid being injured by EMF pollution.
The router guards are a decent band-aid (especially as gifts for neighbors), but for schools I don’t like them. The primary reason is that they still want every child to have an RF emitting device next to their body all day. Having 30 iPads or laptops emitting RF in a classroom is likely more dangerous than the one router up on the ceiling or out in the hall.
As the truth of this technology gets out into the mainstream, schools will be forced to go toward wired solutions. It’s already happening.

Some routers have a setting to reduce signal strength (reducing to 1 on scale of 10 has worked for some). Or, if you remove the antenna, there may still be usable signal. I have found putting a ball of foil over the antenna gives a good reduction in signal.
mark w
I just want to mention as I’m trying to track down this information myself, knowing basic RF Theory. taking off the antennas leaves the transmitter unloaded ( ideally and antenna will present a 50 ohm load to the transmitter ) and may I assume shorten its life span.
Also putting tinfoil over the antenna would act as a faraday cage and I assume reflecting the signal back in.

1. To help sit further from screen – hold down Control & tap the “+” (plus) key, this will zoom almost any webpage into a larger version. Control and “-” (minus) will reduce it smaller.
2. Install F.Lux for free and it will adjust your screen brightness according to your location’s sunrise & sunset.

Dear Jeromy,
I like your article on low EMF computing very much. Thank you.
It gives me food for thought right now as sensitivity to my computer setup varies.
I have not tried laptops recently. Typically all are challenging to me closeup.
I have an HP G60. Sometimes I use it in the field for short periods doing data acquisition. This is okay for me. However more than a few minutes doing word processing is challenging EHS wise. Something rings in my ears.
The HP laptop and printer are on a rolling computer table outside of the office area connected to an old NEC LCD monitor via a 12 foot VKM cable. I find it helpful to adjust the color content in the display to balance my neurology….. this changes. I find it helpful to have good sitting posture, and this changes….
One of the very most important aspects of my work station is that it is in an area of very geoprosperous energy, balancing for me.
A note on the smart phones: in airplane mode only the phone transmissions are stopped. WiFi, Bluetooth and GPS can still be enabled. Most personal electronics such as smart phones, computers and accessories come WiFi enabled. This is also true for newer cars. Using an ethernet cable does not disable the wireless functions. Most people don’t know this and it could be helpful to put a blurb in that direction.
I am glad for your work, your contribution to all of us.
Many Blessings, Michael

The information about Bruce’s computer system was useful. I have a desktop computer kept away. The keyboard/mouse/screen are connected with extension cables. I use a ball mouse and found optical mouse not comfortable (probably due to their laser or may be the consume more power[and hence more EMF) . The laptops have too much radiation on my hands and are far closer to my body than the desktop screen. I can not use them for long. I can use my desktop for more than 8 hours a day these days.
I also use http://www.shop3m.com/3m-ef200lb-anti-glare-radiation-computer-filter-black-frame.html screen and ground it. This way the radiation from the TFT screen does not reach me.

I loved the use of the display projector. I just found a small battery powered display projector called a Miroir. It has a little fan noise, but could be a nice solution for a low EMF environment.
Thanks for the great article – keep up the good work.
Janine
Can you explain more about how this works and reduces EMF?
Vicky
Hi,
Thanks for this much-needed info. I wonder whether you might have any suggestions for the best type of mic to use with a PC. I like the idea of being able to wander around the room and dictate to a voice recognition tool, but I’m not sure what kind of microphone would be EMF safe and still pick up my voice well, if I’m not going to be right next to it. Are there any clip-on kinds that could be safe? Basically, I don’t want my exposure to be any higher than if I were sitting in front of the keyboard! Is this something that you have personal experience with?
Any suggestions very gratefully received!
Best wishes
Jeromy
Hi Vicki,
I have a good corded mic that plugs into a video camera (or anything else with a mic input) that I use all the time.
I got it in Europe – Audio-Technica Model ATR3350.
You can probably find something similar where you are or online. A quick Amazon search found this:
http://www.amazon.com/Audio-Technica-Omnidirectional-Condenser-Microphone/dp/B00I6M3JFC/
The chord for mine is almost 30 feet long.
Good luck!
Jeromy
Marcel
Thank you so much for providing this invaluable information!
I’ve been wondering: has anyone actually succeeded in making a shielded projector that can be used inside a normal apartment (for those of us who aren’t off the grid yet)? I’m thinking about something like a solid box with a lens. If so, how would one go about building something like this?
Best regards,
Jeromy
Hi Marcel,
Give Richard Conrad a call. He can discuss this option with you:
http://conradbiologic.com/
All my best,
Jeromy
Judy
There needs to be simple buyable solutions for people who don’t use iphones, nor are smart enough to build from scratch. Also note I once tried advice via an EHS site, which advised using a projector. So I went & bought an LG projector, but it made me very ill.
My wish is that an electro-sensitive would win the lottery to the tune of billions, then start a company which sells affordable Low GHz. Chemical-Free laptops based on E-paper technology, and accommodating whichever idiotic version of Windows that Microsoft decides to foist in future years. Above all, include proper marketing to ensure that ALL health-conscious consumers get to hear of its wonderful features.
And oh yes, include backwards-compatibility with older USB types such as USB 2.0, and also with older HP printers – specifically the laser jet 1010 series.
steve
I wonder about the Mac Mini.
I have a Mini that’s a few years old and using my gauss Meter, I placed it at a distance that gives off no reading where I sit.
I was planning on buying a new one with a SSD Drive for speed but after you mentioned that SSD Drives are worse for EMFs I’m concerned.
Jeromy
Hi Steve,
The best thing is to try it for yourself. It may not affect you.
With most computers, you have a couple weeks to try it and still return it if it does not work for you.
Jeromy
Nick
Good stuff, Jeromy. I like to see awareness being brought to this subject. I have emf sensitivity pretty bad. I am good for about 2 hours a day of a real computer and beyond that it is head pain and fatigue.
There is a very important breakthrough though that has flown under the radar. Something I can use easily for about 10 hours a day with no symptoms is a Sony Playstation 3. I use it with a wireless keyboard and a directly plugged in ethernet cable, and it has a very quick web browser and I find it browses the internet and uses Gmail and Facebook faster than most PC’s , especially when I disable javascript.
Also, I use mine on an old school CRT television. Flat LED’s give me headaches as well which sucks since they are everywhere now.
PS3 can also have Linux installed on it. Oddly enough a wired PS2 irritates me and i have not tried a ps4 or the new xbox yet. For now Ps3 gives me a ton of internet time with no headaches, literally.
Also i have found that Toshiba and Asus have a cleaner output of EMF’s on their laptops, I stick to those two brands. And I shared your experience that Macbooks are very uncomfortable to use from an EMF standpoint.
Jeromy
Nick,
Great ideas! Thanks for sharing these.
Reminds me of this book, where many people start using a similar setup:

Thanks so much. Most of my friends think I make this stuff up. It’s very real and now I know where and what to look for in a replacement laptop. Thanks

Glad this is helping Penny. So many people are affected, but few have connected the dots so far.
Jeromy

Bill, I’m looking for how a raspberry pi or “other computers that run on 12 v battery”
I can’t figure it out. Laptops can’t run on their battery for more than 3 hours.
Can anyone please expound on this?
Kim kjsv1@hushmail.com
mark w
Battery technology……… current draw. Laptops have a lot more going on than the raspberry pi. It also runs on the risk processor architecture which is a lot more power efficient.
Adam Miller
I just found your site and it is fabulous–wonderful information, suggestions, and recommendations. You asked for recommendations and I blogged about my experience building a low EMF keyboard here:
http://tipsforehs.blogspot.com/2013/01/how-to-make-shielded-keyboard-for.html
Elsewhere on that blog is a review of the Neo2, and also my experience in trying to build a fiber optic keyboard. I didn’t do that well with the Neo2. Does the Neo have less EMF?
The smartphone on airplane mode sounds like a great idea. I’m going to look into that. I like to use a stylus for a touchscreen (or two) to type on a tablet or smartphone to increase my distance from the device.
All the best!
Adam
Jeromy
Hi Adam,
Glad this article helped. Thanks for your site too!
I have heard from others that the Neo2 is worse than the Neo. I actually have the older AlphaSmart 3000 that I use primarily. I also have the Neo and do well with it.
Keep in touch,
Jeromy
Jim West
Is this because the Neo2 has a wireless connection? or?
Jeromy
Jim,
Both the Neo and Neo 2 have an infrared option to send the files. This isn’t active unless in use though, so I do believe either model will work for ES people.
Jeromy
Jim West
Noting…
I bought the Neo2, and measured static with an AM radio. The LCD screen emits constant EMF static. But this is only when close to the screen. The keys emit a 1/10th second zzzzzzt of static with each press.
Probably 1/10000th the EMF of a regular computer, nevertheless, there is some EMF there.
Jim West
And thanks for your article!

I was looking at the Dell Latitude E6510 that you recommended, but it comes with a lot of options and configurations as shown in the quote below. Can you specify what your configuration was in detail? I know that you are sensitive to the SSD hard drive, which also leaves me puzzled because I have seen other emf sensitive people recommend it because does not have the rotation if I understand it correctly.
I presently had problems with my laptop building up heat, and bothering me, but once I realized the CPU was over heating because the fan was dirty and cleaned the fan the air flow was better and heat reduced. I do not think they should run hot unless there is an air flow or cooling problem. The Dell Latitude from all that I have studied has an SSD hard drive. I did enjoy all of your information.
“Dell Latitude E6510 start at just $729. When configuring your E6510, you can choose between 6 different Core i3, Core i5, and Core i7 CPUs. You can also decide between a 1366 x 768, 1600 x 900, or 1920 x 1080 resolution screen. Both discrete Nvidia NVS 3100M graphics and integrated Intel graphics are available. Storage drive options range from a 160GB 5,400 rpm unit on the low end to a 256GB SSD on the high end, with lots of 7,200 rpm and encrypted drive options in between. The base config starts with 1GB RAM, but can be specked up to 8GB. Though the default battery is a 6-cell unit, a 9-cell option is available as well.”
I am puzzled about your information about the SSD hard drive as I find other people who are EMF sensitive highly recommending it because it runs quieter, cooler and has no rotation. Below are some quote on the hard drives.
“Since no such rotation is needed in solid state drives, they use less power and do not generate heat or noise. Hard disk drives use more electricity to rotate the platters, generating heat and noise.
HDD contains moving parts – a motor-driven spindle that holds one or more flat circular disks (called platters) coated with a thin layer of magnetic material. Read-and-write heads are positioned on top of the disks; all this is encased in a metal case.
SSD has no moving parts; it is essentially a memory chip. It is interconnected, integrated circuits (ICs) with an interface connector. There are three basic components – controller, cache and capacitor.
HDDs are heavier than SSD drives.
SSD drives are lighter than HDD drives because they do not have the rotating disks, spindle and motor.”
Brandon
Thanks for posting this. Each year it seems I have been slowly having more trouble spending time in front of my computer. I am thinking the biggest factor for my set up is the monitor which sometimes feels like it is microwaving the backs of my eyes.
I am so happy with your idea of a rear projection monitor. Not sure how the science is different than EMF, but natural light vs electronic light (especially from monitor screens) is a factor for health.
Will be looking into how I can implement a mellow monitor for my office. Best idea for my situation I have seen yet. Thanks again.
Janine
Did you ever figure out a helpful monitor? The monitor is the most problematic of my computer components.
Rosemarie
Jeromy —
I have to stick to desktop computers and am looking at Dell OptiPlex 3040. Have you heard anything about the OptiPlex line?
Jeromy
Hi Rosemarie,
I have not tried this line. In general, desktops are better. You can put them farther away and use a screen that you self-select for your body so you get less symptoms.
Good luck. Let us know what you find.
Jeromy
C Young
Besides resorting to a projector, what type of monitor is lower EMF and easier on the eyes? I do need good color as I do design work.
Jeromy
I have done well with older Dell models (years 2010-2012). You can still find them on Ebay. Here are some:

Judy
I’m flinching at the thought of such HUGE monitors – the bigger the worse the EMFs.
I believe BenQ 15″ used to be the most health-friendly, but it’s important to find out if any particular model is easily and accessibly dimmable via the monitor’s buttons.
Judy
In response to EMF-REFUGEE:
(1) Jeromy, you overlooked that many tech-users ARE STILL YOUNG. Older people are way more vulnerable to tech AND ALSO have CUMULATIVE years of being virtual guinea-pigs to tech.
(2) Gabapentin 300mg. helps to a degree, when popped prior to computer use. Tell your doctor you suffer severe headaches, and know people who were helped by gabapentin. Then chances are, any doctor with some pity, will offer a scrip.
An alternative may be a combo of Gaba and licorice. Perhaps some health food stores may offer that combo?

Renee
Hi Jeromy,
You mention in your suggestions of laptops you had a Toshiba modified to a processing speed under 1 Ghz. How difficult is this to have done? Can a computer tech person do this easily?
Also if I’m comparing processor speeds of an Intel Core i3 with 3M cache, 1.80 GHz to an Intel Celeron N2840 Processor, 1M cache, up to 2.58 Ghz), which is slower/quieter?
Thanks,
Renee
Jeromy
Hi Renee,
Yes, it is somewhat difficult to do. You and your computer tech need to know what you are looking to do (lower processing speed and reduce fan noise.
In general though, you need to test a computer to see if it will work for you. Sometimes higher processing speeds can actually be better for ES people. There are several factors involved.
Here is what my colleague said he did with his computer:
“This unit has been customized with both hardware and software.
It started as a Satellite L755-S5365.
It runs Windows 8.1 w/ Media center (was Windows 7).
There are many more mods done besides the Samsung SSD including memory, and network adapters.
It has the latest Intel controllers to control processing speed.”
Jeromy
Zachery Jenks
Hey guys. Not sure if anyone still posts here, but I’ve been through maybe 30 laptops / desktops at this point, and wanted to point you guys to the best one I’ve found so far –
The Asus X205TA.
It runs on an extremely low-powered Atom Cpu (Z3735F), 2GB ram, 32Gb eMMC hdd,
with an 11.6″ Twisted Neumatic screen.
The laptop features no PWM, so no flicker whatsover.
I’ve purchased 3 at this point because of how I well I react to it.
It’s not a powerhouse by any means, but perfect for browsing, documents, Youtube, Netflix, reading, lite gaming…
Battery life is around 8 *actual* hours as well.
Jeromy
Thanks for the heads up Zachery. Excellent info.
I will keep this in mind for my next laptop purchase.
Jeromy
Shelley R
Zachery how is the Asus working for you?!
mark w
While I was over here, I thought I would mentioned that as a laptop and device roamer i have TightVNC installed and if possible RDP enabled on all my systems.
this allows me to connect from one device to another from any device that is networked even older devices. I can connect to my MacBook Pro from an ancient Toshiba libretto 70ct if I want to (screen sizes are way too much mismatch, but i can…).
I thought that some might find this helpful, for those out there if you find one particular computer less bothersome than others and it can stand a network connection to remote desktop to a more powerful system in another room.
Tanya S
Do you have a printer that is low EMFs? If so, are there guidelines to how close/far the printer should be placed to the computer?
Jeromy
Hi Tanya,
The printer should not be a problem, as long as the WiFi / Bluetooth is disabled and you use a wired connection to it.
The RF from a wireless printer is incredibly strong, so watch this. You can test it with this RF meter (my favorite for the price). Use the code EMFA-10 for a 10% discount:
http://slt.co/Products/RFDetectors/Acousticom2.aspx
Keep the printer unplugged when you are not using it. This will reduce any electric fields/EMI it produces.
Jeromy
Carla
I have been looking into lower EMF options for a keyboard and mouse – and am a little confused about something.
I have found for example that the wired Cherry brand keyboard below requires only 15mA of power for usage. Voltage not mentioned. Has many different product approvals.
http://www.mouser.com/ds/2/71/G85-23200EU-2-1-6-162-1079762.pdf
My question: does a low mA necessarily mean it will reduce EMF exposure. Or does the lower mA indicate it could be even worse (losing the excess – much like incandescent vs halogen bulbs).
Simarly – I have found wired mice as low as 30mA (I don’t want to invest in mouse balls just yet 😉 … not bad compared to the 250mA I am using now … but still … I am not sure.
Any advice would be wonderful 🙂
Carla
Jeromy
Hi Carla,
I find that the biggest issue is the electric fields and EMI being generated by your modem/router/computer that are then conducted along the wiring of your keyboard to your body. This can be eliminated through proper grounding of your equipment. I would focus on this.
I show you how to do this in the following video:
https://www.youtube.com/watch?v=ULV0jKXcnJo
My best,

John
Hello and thanks for the article, lots of good information here.
I use an old iMac (2006) as the CPU which is about 5 meters away from me (in another room, display facing the wall) and an external LED display (ViewSonic) one meter away from me. This works pretty well but the computer is getting old and slow.
The strange thing is that when I try to replace the iMac with a MacMini, I instantly get trouble. I have a MacMini 2009 (an older model but updated with a SSD) and a newer 2011 model (without a SSD) – but both are bad. They start to cause symptoms in 10 minutes!
Then on the other hand an older MacMini (2007) is fine but it’s way too slow too use.
I don’t understand it – what can be so different with these newer models? And that SSD issue is so puzzling, you mentioned it’s not good for you but I know people who say it’s way better than HDD because there is less magnetic fields.
Sometimes I think if the main issue is that the body just reacts to the change when you try a new computer. It senses something is new and different. Maybe the computer itself wouldn’t be that bad EMF-wise but the change makes the body react because the frequencies are slightly different than the body is used to tolerate.
Any thoughts?
Jeromy
John,
Great questions.
Have you read Arthur Firstenberg’s book? He talks about why Apple computers are some problematic for ES people.
http://www.cellphonetaskforce.org/?page_id=1427
I’ve tried dozens of laptops in order to find models that work for me. I have also tried to “push through” on computers that I had symptoms. This was never a good idea for me. The longer I tried using them, the worse I got.
We are all different in our sensitivities, but there seems to be a common experience of reacting to new Apple computers. It could be the circuitry design as Arthur mentions. I know of a few people who became ES after getting a new MacBook Air.
Hope this helps.
Jeromy
Jason
Hi, great article. Looking to get rid of my iMac. Do you have an update on which new release Dell laptop has the lowest EMF?
Jeromy
Hey Jason,
The only new Dell laptop I have tried the past year is the low-EMF one sold here:
https://www.amak.se/store/
However, I could feel this quite quickly, so it would not work for me (or the ES person who bought it). I think most newer Dell laptops are not great for ES people. Could be the newer processors or screens.
I would try various models to see what works for you (just make sure you can return within 2 weeks). That is what I did to find the models I list above in the article.
My best,
Jeromy
Jason
Thanks for the reply. Do you have any suggestions for a desktop computer with low EMF’s? Or are laptops my only option?
Jeromy
Jason – a desktop computer can work quite well, provided that you keep the actual unit farther away from you (perhaps on the floor behind your desk). 5-8 feet away is ideal if your cords will allow for it.
Then you just need to find a computer screen that works well for you.
I know a lot of people like the iMac desktop computers, but I don’t typically recommend them because of the large screen and the processor is right behind the screen on your desk.
Jeromy
Jason
Thanks for the reply. I am looking at buying a laptop rather than a desktop and am looking at the Dell inspiron 17 inch 5000 8th Generation Intel® Core™ i7-8550U Processor (8MB Cache, up to 4.0 GHz) or a Lenovo Yoga 510 14 Touchscreen Intel Core i5 Processor 8GB 1TB Notebook up to 2.80 GHz. Do you know which of these would be the most suitable for low emf’s?
Jeromy
Hi Jason,
Ultimately, you will need to purchase one and see how you do with it. I typically know within a day if a computer will work for me. If not, I take it back immediately.
I would avoid touch screens. You want to use an external keyboard and mouse. Also, the higher the processor speed and RAM, generally the more symptoms ES people experience. I have one Toshiba laptop with 2 MB of RAM and a 1 GHz processor. It’s slow, but I do all my writing on it.
My best,
Jeromy
Dave Martin
You must have discussed the metal frame and case that seems to shield the user from EMF’s. The Latitudes have a magnesium shell. One site mentions that magnesium has a shielding effect. It would make sense in that one of the laptops that has little effect on you also has an i-7, which is a fast CPU, and should be troublesome to those that are sensitive.
Jeromy
Thanks for your comment Dave.
I have not yet read about the EMF shielding properties of magnesium. Could you share your sources?
My Latitude E6230 has an i5 processor. It certainly has been a good computer for me.
Jeromy
Rebecka
I thought about buying a desktop computer for a long time, but now I realize that a laptop is still more flexible. I can (should) use wired keyboard and mouse with my laptop (and maybe an external monitor). At the same time, I always have the opportunity to take it with me if necessary. So a laptop it will be.
Now the question is which laptop. I have a MacBook Pro from late 2012 now and I understand from the article and the comments that Apples computers are the worst. It’s sad because I still like macOS and its programs. However, I dislike the lack of various ports and I dislike buying multiple dongles. I want a memory card reader, Ethernet port, USB-A and HDMI or DisplayPort in addition to USB-C. I would also appreciate replaceable battery as well as the ability to upgrade RAM and storage in the future.
I will review which video editing software is available for Windows. Maybe there is something good (more than expensive Adobe Premiere Pro). DaVinci Resolve seems interesting.
Which laptop would you recommend for video editing? I’m going to edit 1080p videos but it may be able to handle 4K as well. I’m an amateur and want to make YouTube videos so nothing professional at this time.
“As a general rule, older Dell and new Toshiba laptops seem to work well for electrically sensitive people. Anything by Apple, along with HP’s and the newer Dell laptops tend to be high EMF machines”
So, maybe I should look at a Toshiba if I’m buying a new one today? How is Lenovo and Asus? Anyone who knows?
I really want an SSD and I don’t think I really understand how SSD or HDD can play any role? I can also imagine an SSD/HDD hybrid. SSD is primarily important for starting the computer, closing/opening programs and when working with video editing. For long-term storage, an HDD should work fine.
Toshiba Satellite Pro A50 is a new laptop from Toshiba. It should handle video editing, I think. Is it a low-EMF laptop?
Note: I don’t think I’m ES, but I still want to minimize EMF around me when I’m sitting in front of the computer (which I do a lot). I experience headaches but I’m not sure why.
Jeromy
Rebecka,
It’s hard to say. You need high processing power for video editing, which non of the Low-EMF computers I recommend have. I don’t know any ES people that do video editing, so I can’t really help with your question. As I’ve mentioned, try things out to see how you do with the computer. Everyone is different and you may find something that works perfect for you.
Jeromy
Rebecka
Hello Jeromy.
How much processing power you need for video editing is also dependent on the software/OS. The lower-performing MacBook 12 can handle 4K in Final Cut Pro (Adobe Premiere Pro would be a different story). However, I suppose it doesn’t matter if I choose it in front of a MacBook Pro. Both are unacceptable to ES people?
I don’t think I’m ES, but I want to avoid becoming ES in the future too.
Maybe use the computer with Defender Pad? I read that you recommended it, but you don’t recommend other radiation blockers for smartphones (not safe or working).
Otherwise, I understand that having Wi-Fi and Bluetooth turned off is important. Wired keyboard and mouse and keep distance.
I have to think further. I like macOS and are considering a new MacBook Pro (15 ” from 2015). I’m still unsure when I read that Apple’s computers are the worst. At the same time, it may not matter if I still have to choose a higher-performing Windows laptop?
Rebecka
Jeromy
Hi Rebecka,
In your shoes, I would just do all the steps possible (low-EMF internet connection, turn off all wireless, create space between you and computer and work in a low-EMF environment) and then still use a Mac computer (for your processing / software needs).
That should be the way to do your work in the healthiest way possible.
Keep in touch,
Jeromy
Rebecka
Thanks for your advice. Appreciated.
Rebecka
Rachael Stephens
Hi Rebecka and Jeromy,

When I became so sensitive that I could no longer use my iMac at home at all, I was pleased to discover that I could still use the Dell desktop computers at my nearby public library. They are Optiplex 390 (from 2012!). The only problem at the library was the RF coming from the smart phones of the people seated near me at the computer and/or the library’s wifi. But if I was the only person at the computers, I could stay there for an hour without any symptoms, sitting up close the computer.
This is indeed a wonderful article and website, as well as list of comments!

Madelyn
Hi Jeromy,
I work in an office building and have tested my office for EMF’s. I have found that the highest levels are in the power strip/power cords under my desk, but I’m not sure there is anything I can do about this. They sit all the way at the back of my desk and my legs are up front, so is distance helpful? Anything else I could do with these power cords under my desk?
Also, I know research is limited on this but I have a Himalayan salt lamp in front of my laptop docking station at work in an effort to reduce EMF’s. However, this salt lamp has a dimmer cord, which I have read is bad and produces more EMF’s than an on/off switch. Am I doing more harm than good? Any thoughts?
Jeromy
Hi Madelyn,
The power strip behind your desk is not a huge problem. Just keep your distance. However, if it were me, I would get the shielded power strip seen here:
http://www.stetzerizer-us.com/shielded_power_strips_and_cords.html?a_aid=esh
The Himalayan Salt lamps do nothing to reduce EMFs. The dimmer switch will only add EMI / dirty electricity to your home wiring.
My best,
Jeromy

My husband works from home on a work-provided laptop. He uses a wired connection and sits the laptop on our kitchen island (not his lap). However, we tested his laptop and have found that the strongest EMF’s are released from the keyboard area where his hands/fingers are. So we are considering buying a wired keyboard and mouse for him to use with his work laptop so he does not have to touch the computer while in use. Will this help a great deal?
Also, I saw the Defender Shield laptop pad that you have recommended, but would it be helpful in this situation since he does not use the laptop on his lap? From what I’ve read those only pads only block EMF’s from the underside of the computer…

Maddie,
Indeed, use an external keyboard and mouse. Never use WiFi. Use battery power for the computer (not plugged in) and use a Low-EMF laptop like the devices I list above in #5.
To show you the difference, here is a MacBook Pro plugged in. The electric fields are over 1,000 V/m! You want E-Fields below 5 V/m when you work at a computer.
https://www.emfanalysis.com/wp-content/uploads/2018/05/Electric-Fields-from-MacBook-Pro-Pugged-In-Arrow.jpg
Here are the EMF levels at my laptop – very low (0.8 V/m) which allows me to use the computer much longer:
https://www.emfanalysis.com/wp-content/uploads/2018/05/Low-EMF-at-Laptop.jpg
You also want to ground your Ethernet cable as I show here:
https://www.emfanalysis.com/low-emf-internet-connection/
If you need better EMF meters to test all of this, read this page for my recommendations:

Hi Jeromy,
I was wondering when you wrote that you experienced symptoms within 30min to 2h of using a laptop what was the distance between your body and the laptop? I recently became electrically sensitive and am now using my laptop from 3m away with an external mouse and keyboard, which seems to give me milder symptoms. I think I’m just concerned that one day even this set up may not work for me if my symptoms worsen.
Jeromy
Hi Ran,
My laptop is typically 1 meter away from me. 3 meters would be tough on the eyes, unless you have a screen magnifier.
Realize that the thing you are likely reacting to are the electric fields and EMI being transmitted to your computer on the Ethernet cable. Read this article to see how to reduce this:
https://www.emfanalysis.com/low-emf-internet-connection/
Most ES people do way better on the computer when they take steps to reduce the EMI coming to their computer. This can mean the difference between only tolerating a computer 20 min or being okay for up to 3 hours (when the battery runs out of juice).
Hope this helps. Keep us posted.

A culprit just may be HFN. I came across a thread where people speculated that high-frequency noise, such as from chips that are inside optical-mouse & so forth, are what might be a major source of symptoms.
I found that food for thought, even if not yet proven.
Matt
I have a device that I like to use that has absolutely 0 EMF’s, doesnt require any electricity whatsoever, can be carried anywhere, and lets you write as many pages as you can carry. And the total costs for this device are less than $10 at any wal-mart. The device is called a notebook and pen or pencil. Used successfully for hundreds of years. 😉
Rebecka
Is optical mouse/keyboard as bad as Bluetooth keyboard/mouse? I suppose wired is still better than optical as well, but is optical any better than Bluetooth connection?
Rebecka
Ignore my last comment. I suppose RF mice is just as bad as Bluetooth ones. It’s just two types of wireless technologies…
Wired it is!
Marianne Broome
I have a desktop iMac with wired keyboard and mouse. Don’t have a laptop. I notice with my Trifield meter that the electric field near my keyboard is huge and not much better at my mouse. It is much stronger than my monitor! I understand that low EMF keyboards won’t work with a desktop Mac. Is there a way to solve the keyboard problem? Can’t find any info on this. Thanks for some help!
Drew
Hi Jeromy,
Have you tried the AlphaSmart Dana, or seen anyone measure its emf output? It seems like it might offer significantly more functionality than a neo, if it’s levels are not much higher.
I know you don’t feel able to recommend newer phones, but do you happen to have a list of older ones that have worked best for you and colleagues? Based on your colleague’s story, it sounds like the Galaxy SIII would be a good one to pick up on eBay. I don’t need anything new or high powered.
Many thanks for any advice you feel able to offer!
Jeromy
Hey Drew,
I would read through this for some ideas on smart phone use:
https://www.emfanalysis.com/headsets/
I have not used the Dana yet. If you try it out, let us know.
Keep in touch,
Jeromy
Drew
Thank you for your time Jeromy. After some research, I chose the Neo over the Dana, because it has a sharper screen.
About cellphones, I was referring to your colleague’s approach of using a phone with “usb OTG” connected to a wired keyboard and mouse, which you described as “truly a low-EMF computing solution” for doing email etc, while offline, and then sending when the cell radio is on.
I’ve noticed that the point at which you stopped feeling able to recommend the Samsung Galaxy phones was the S6 – which marked a transition for Samsung to using all metal backing, like Apple has. I’ve checked some of the ifixit teardowns for these phones, and the metal is always placed where it will direct EMF at the user – from both processing components, and much of the antenna real estate. Perhaps the fact that earlier Samsung’s were all plastic could be a major factor? All Apple’s phones, besides the 4S (which worked well for me) have it backwards.
Also, it is possible to “root” older Samsung phones to load newer a newer OS, and extend the life. There are trustworthy developers making these OS versions at XDA (the official XDA developers are most trustworthy.). There are also some good professionals installing the software. Have you seen colleagues or clients benefit from these resources?
Thank you so much maintaining this site to help people, despite the impact it must have on you.
Drew
Apologies: the S6 has a metal frame/chassis, not a full metal back – I misunderstood. I just looked at it’s teardown, and it seems to have some metal support underneath the all-glass backing, but it’s hard to tell how much. Both the S6 and S7 have their frames placed just under the display glass (so placed on the user side.) More complicated (and much better) than I made it sound, in the previous post, in terms of the metal placement. You’re right, it must be about strength of components and number of radios. The S7 apparently needed a (tiny) liquid cooling system it was so powerful and (potentially) hot.
I’m sorry for the potentially confusing material – please feel free to delete that part of my post – I’d like to avoid confusing or misleading anyone.
Jeromy
Thanks for the clarification Drew.
That more people (anecdotally) started to feel pain in their hands and arms when using the newer Samsungs (and iPhones) is likely a combo of the two things – higher RF output and the interaction with additional in the metal cases.
The metal cases of Macbook laptops is the primary reason most ES people don’t do well with them.
I appreciate your thoughtful and well-researched comments.
Keep in touch,
Jeromy

Thank you, Jeromy, for publishing informative articles about EMF pollution and hosting the much needed discussions.
I want to mention the Dell Precision M4300 model PP04X as another “low-EMF” laptop, in addition to the Raspberry Pi B (Bill Bruno) and a few other quiet computers listed here. I personally have struggled over EMF sensitivity for many years now, e.g.
https://www.raspberrypi.org/forums/viewtopic.php?f=62&t=109892&hilit=In+search+of+a+quiet+mini+computer&start=75
where I tried to find out. in May, 2015, why the newer Raspberry Pis are no longer calming as the Raspberry Pi B.
I have now discovered that not only computer hardware, but software (like different versions of Windows) can also contribute to increased EMF pollution (!!). Currently, I am in the process of assembling “low-EMF” computers with light-weight Desktop OS (Operating Systems). Hopefully, I can soon make these available (e.g. through eBay) to help out people in desperate needs,,,,

I had earlier found a magnesium manufacturer source, (which I cannot now find) but this is similar:
Magnesium Product
— Electronic parts
“It is used to reduce the weight of electronic parts in IT/Mobile because of the excellent electromagnetic shielding and light weight of the magnesium alloy, and the E-form series alloy capable of cold molding is used most often. – AZ31B, E-form alloy series …”
http://www.posco.com/homepage/docs/eng6/jsp/product/s91p1000110l.jsp?seq=32&tbKnd=172
— so the lower weight of the metal combined with the RF shielding seems to be the reason why Dell used it in their Latitude line.
Here, Gupta, 2017, states :
“Table 4 lists the electromagnetic shielding capabilities of magnesium, its alloys, and other materials. Table 4 clearly reveals the superiority of magnesium over that of aluminum.”
https://pdfs.semanticscholar.org/e686/7bf08f83c73f90a3cd6fe54f8ed7685b8b2a.pdf
S. Gao, 2018, shows :
“We previously found that in the frequency range of 30–1500 MHz, the SEs [shielding effectiveness] of pure magnesium, AZ31, AZ61, ZK60, ZM61, and other commonly used magnesium alloys are significantly better than those of aluminum alloy with the same thickness but are lower than those of copper and copper alloys.”
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5786048/
and here’s an interesting statement from “Assembly magazine” 2016:
“Electronics assemblers like the strength, durability and light weight of magnesium, too. Magnesium also dissipates heat and shields against electromagnetic and radio frequency interference. The housings for cameras, cell phones, laptops and portable media players are commonly made from magnesium.”
https://www.assemblymag.com/articles/93430-assembling-magnesium-parts
It could be, that by your experience, you found the laptops makers that did the best job to shield the laptop from outer RF, (the workplace) which–at the same time shields the user from the RF from inside the laptop. Though, shielding, I assume, is used between some components to prevent electromagnetic interference.
I looked at some of the pics for the E6510 palmrest and touchpad cover–parts on ebay. The underside has a copper colored material on it’s surface. It looks like shielding. Besides that, the keyboard seems to also have a metallic coat on its’ underside–silvery color. – both perhaps protect the users hands.
And this was interesting, I googled Dell Inspiron 5520 palmrest and touchpad cover. Some of the parts sellers show the undersides. They were silvery, but not copper colored. So it seems the latitudes have the copper coating on the undersides of the palmrest and keyboard areas–while the Inspirons do not.

Hi. How do I know the year the monitor was built? And where do I find older monitors?
Carolyn
Great suggestions, thanks! Interesting that I also find my ACER Aspire to be the most tolerable, though at the moment I´m on it too much and am starting to be bothered by it. I like your suggestion of switching from one computer to another now and again – I will have to try that as I have a couple of others on hand. I have also in the past have had good experience with Toshiba Satellites, so will look for one again – my last one finally died on me after about 7 years 🙂 And then, someone gave me an HP Elitebook, which someone gave me and I have never been able to use for more than 20 minutes at a time.
For a long time I used a Sony Smartphone (Xperia) connected via a USB ethernet adapter, and agree that I was much better using that for emails and even checking messenger and facebook, than on my computer. Unfortunately it finally died, and I have yet to find another smartphone that works as well (one I bought can´t connect via ethernet -though I do use it similar to your suggestions, mostly in airplane mode to download and send email etc. (I find I can use it with messenger and even Facebook to an extent). Still hoping to find another Sony Xperia though.
I like the suggestion about the electronic keyboard too – had never heard of that. Am wondering how big the screen is? It is just used for entering text then? Can the text then be used in a Word file for example?
Thanks for all the suggestions!
Jeromy
Thanks for the feedback Carolyn. Wonderful that you are finding solutions that work for you.
The Neo’s screen has 3-4 lines of text. I use it to create drafts and then transfer the file to a Word document on my Toshiba’s where I do my editing. It works well for me.
Keep in touch,

BIG Tip: Use the laptop without the battery plugged in. Makes a HUGE difference!
Drew
Hi again Jeromy,
Based on how this list has changed over time, do I understand correctly that the Dell Latitude e6510 is probably the computer that has consistently worked best for you over the years?
The i5 Latitude e6230 seems to be approaching the limits of your comfort. If you had one with an i7 3ghz processor, would that likely not work for you?
Drew
Hi Jeromy,
Based on the ways this list, and the comments section, have evolved over time, do I understand correctly that the Toshiba Satellites are your current go-to computers, while the Latitude e6510 has worked most consistently and reliably well for you over the years?
The Latitude e6230 appears to be the highest powered laptop still listed in 2020 — and seems to push the limits of your symptoms most quickly, given what you’ve written. Do you feel it’s unlikely that an i7 version of the e6230 would be use able for you? Have you tried one?
Many thanks for your time in maintaining this article, and the ongoing discussion.
Jeromy
Hey Drew,
Thanks for your comment.
My primary laptop is the Dell Latitude e6230. I have multiple models in case one goes down (they are older). I also use the Acer Aspire listed above quite often and the Toshiba’s for writing. I rotate through all of them.
I have not used the Dell e6510 in many years as the e6230 works so well.
I use the i5’s because they have enough computing power. I recently put in a 320 GB SSD into one of my models as the HDD crashed. It is an incredibly fast computer and I noticed no added EMF effects. I simply have never tried the i7 as I have no need for that.
The past few months I have been using older Acer Chromebooks (from 2015). They work great for emails, YouTube, Zoom, web stuff, etc. I’ll add more on these to the article above, but here are the models if you want to do an ebay/Amazon search and get one yourself:
Here are two Acer Chromebooks on Ebay:
https://www.ebay.com/itm/Acer-C730E-C555-Intel-Celeron-N2840-2-16GHz-4GB-Ram-16GB-Flash-Chrome-OS/154054347734
https://www.ebay.com/itm/Acer-C730-Series-Chromebook-16GB-eMMC-4GB-RAM-Intel-N2840-CPU-ChromeOS/324267767567
There is a Zoom app for Chromebooks as well, so it is super easy to use Zoom on these. The machines are low EMF (Celeron processors, which are fast enough for this machine) and they are very quiet as well. You do need to use an Ethernet to USB adapter for the internet (no Ethernet ports on Chromebooks, only USB). I like this adapter, which you can ground to reduce electric fields/EMI. You can attach your external keyboard and mouse to it as well.

Hope this helps,

Emiliano
Hey Drew, I have the same doubt. Did you buy the Dell 6230 with the I7???
George
Hello Jeromy,
thank you for all your information and willingness to help emf sensitive people. I would please like to ask you, now that Toshiba doesn’t make laptops any more, are there any suggestions as to what brand of laptop we emf sensitive people should aim towards (August 2020)?
Thank You
Jeromy
Hi George,
Thanks for writing.
I have not found any new laptops that work for me (and others). However, the older one’s I list above can still be found on Ebay and Amazon used/refurbished and are good machines.
That is the route I would go.
Hope this helps.
Jeromy
Tom
Hi Jeromy,
Thanks for the post. I bought an alpha smart and love it.
Do any of the laptops you list have PWM, screen flicker? They’re too old to be listed on the PMG ratings.
And this is obviously a personal choice but some of the laptops you listed have 11 and 12 inch screens. I’m mostly going to use it for writing, editing from the alpha smart. Do you have any challenges writing on a screen that small?
Thanks.
Tom
Jeromy
Hi Tom,
Thanks for your comment.
I have great glasses and keep the laptop about 3-4 feet from me generally. That works for me even with smaller screens.
As for flicker free screens, look at these:
Samsung Low Flicker Monitor: Samsung Model S32F351FU
https://amzn.to/2LyCx8e
And this one: https://amzn.to/2Xl2En6
No Flicker Paper Like Screen: https://amzn.to/2NySkWX
BenQ and EIZO Flexscan monitors are also flicker free with built in blue-light reduction technology.
Hope this helps!
Jeromy
Tom
Hi Jeromy,
And I saw the Dell Latitude E6230 you like comes in a 14 inch -E6430, and 15 inch – E6530.
It sounded from the article like they were all the same but with different screen sizes. Although it also seems like you would have listed the other latitudes if they worked for you (there was another you liked that was 2012 but that seemed fairly old.)
Again I’m looking for mostly writing, email, and net use. I’d prefer a 15 inch screen.
Any thoughts, and if the larger latitudes I mentioned would work?
Thanks.
Tom
Jeromy
Tom,
I would simply try them out and see how they work for you. I have tried out nearly 30 laptops, often returning them after a week, in order to find ones that work for me.
Most ES people have to cherry pick devices to find some that work for them. Just make sure you get equipment on Amazon or Ebay that you can return in the 14 day window.
Keep in touch,
Jeromy

Hi Jeromy,
As far as monitors are concerned, while doing my research I saw that some recent LG and Samsung ones mostly carry a 2-prong power plug so that means that they are unearthed and that they produce a large E-field. They can however be earthed through the VGA or HDMI cable which is connected to a desktop’s tower (if you are using a desktop and that desktop is connected to the power plug through an earthed 3-prong plug). I would however prefer a monitor which has a 3-prong plug and is therefore directly earthed through that. Would that be a correct assumption?
As I am about to buy a monitor, I decided too choose one that isn’t too large as another person mentioned in the comments, a bigger screen usually means more emf (or a larger emf field). These are some of the models I’m considering, by Dell, HP, ASUS and AOC.
– Dell E2016HV 19.5″ (produced since 2015 )
– Dell E2020H 19.5″ (produced since 2020 )
– Dell E1920H 18.5″ (produced since 2020)
– HP P204 19.5″ (produced since 2019)
– ASUS VS197DE 18.5” (produced since 2013)
– AOC e970Swn 18.5″ (produced since 2013)
– AOC e2070Swn 19.5″ (produced since 2013)
Would you suggest one or any of these or any of these models (or brands in general) for ES people or is there another brand/model which you know to be low-EMF or better for ES people? Thank You!
Jeromy
Hi Nick,
Great question. Here are three points that should help:
1.) Most ES people need to cherry pick their equipment, which means trying out multiple devices until you find one that works well for you. I have done this with 30 different laptop models to find 4-5 that work well. I always buy stuff I can return within 14 or 30 days. Buy a few and keep the one that works for you.
2.) HDMI cables are huge radiators of EMI / electric fields. Watch out for this and shield them the best you can.
3.) Flicker is an important issue for most ES people. This video shows what flicker from certain lighting can be like:
https://youtu.be/pchmb6ekCMo
Here are flicker free monitors:
Samsung Low Flicker Monitor: Samsung Model S32F351FU

And this one: https://amzn.to/2Xl2En6
No Flicker Paper Like Screen: https://amzn.to/2NySkWX

Anyone have any success with bigger monitors? I have a 26″ iMac that I want to hardwire monitor to and put at least 6 feet away from me, but I use it as a TV as well so I’d love to find a big, low-EMF screen.

Hi Lucien,
You might also want to try a flicker free monitor. Here are two examples:

I set up my smart phone with a USB C Ethernet adaptor and merrily thought I was safe to browse, type emails and even play the odd game on the phone. But didn’t feel good. Not expecting any issue at all I decided to test with a Cornet meter and picked up RF in the phone and in the adapter itself. I found the same in another adapter that has 3 USB ports and ethernet. Even simply having the adapters plugged into the phone creates this issue. The house has no Wifi and no one else’s wifi available. So not only do I not understand but I’m horrified. Any thoughts would be very much appreciated.
Jeromy
Hi Fiona,
It could be that your Cornet is picking up EMI/electric fields that will be on your Ethernet system and made worse by the USB-C adapter. If it is actually RF, then perhaps your device is not on Airplane mode?
My best,
Jeromy
Matt
Computers are such a minefield! Some I’m absolutely fine with, plugged in, using wifi and others give me the fritz just using them for 5 minutes!
Some anecdotal thoughts regarding choice.
– Low powered fan less machines may be a good option. No fans should mean lower magnetic fields. Even though it’s fairly modern tech I do absolutely fine with Microsoft Surface Pro’s I think for this reason (40W power supply, long battery life, no moving parts).
– If you’ve got a new machine, be aware that your symptoms could be in part from the off gassing of the components. Ironically using the laptop would probably make it off gas faster but that may not be possible due to symptoms. Maybe try storing it in a well ventilated room.
– Experiment with the laptop being plugged in, on battery, in a different room etc. There may be a good enough work around.
Jeromy
Great points Matt!
Indeed, working a low-EMF room is key. As is having a low-EMI internet connection:
https://www.emfanalysis.com/low-emf-internet-connection/
Cherry pick devices and send them back until you find the ones that work well for you. I have 5 different models that work for me (after trying dozens).

Jeromy – PC power supplies (ATX PSUs) have become a real problem for building a low-EMF PCs. Even 5 years ago, I was still able to find power supplies that don’t create too much dirty electricity (say about 200-300 on the Alpha Lab Line EMI meter) and RFI. Today, it seems like a lost cause. I built several new systems in the last year, tried a few different PSUs (Antec and Corsair), but invariably, each power supply caused readings of about 1900 on the line EMI meter, and was screaming on the AM radio band (when holding a Uninex radio near it).
My guess is that these switching mode power supplies have to get more aggressive to satisfy ever greater energy efficiency standards. Unfortunately, you can’t even buy the older models anymore (and even if you get used ones, they don’t fit into new PC cases, because PSUs are now bottom-mounted instead of top-mounted).
Public testing data on PSU EMI and RFI seems non-existent. The few discussions in tech forums I can find on low EMI PSUs are derailed by toxic skepticism. People who ask the questions are immediately verbally put on trial for why they would want such a thing, and when they admit it’s due to health reasons, it’s downhill from there.
I’ve even looked into linear ATX PSUs marketed to audiophiles, which seem mainly optimized to produce as little noise as possible on the DC output rather than the AC input, though I imagine that not producing a lot of noise on the AC circuit is also an objective, to avoid feeding noise into other audio equipment.
These things are absurdly expensive. The cheapest linear PSU I found, the HDPLEX 300 W Linear Power Supply with ATX adapter, sells for over $600. A new high-end device called the Optimo ATX is going to sell for over EUR 3000.
Do you have any leads on current, conventional power supplies that produce less EMI/RFI? Are there any niche manufacturers that make low EMI/RFI ATX PSUs?
Nick Graham
Hi Jeromy!
As far as your laptop suggestions are concerned, you mention that newer Toshiba laptops are better for ES people. As mentioned in one of the comments here Toshiba no longer makes laptops but I noticed that another company called “Dynabook” mentions that it is originally known as “Toshiba”, meaning that they probably picked up where Toshiba left off. Have you tried any of these Dynabook satellite laptops? Are they better for ES people? Have you tried any new laptop model/brand which is better for ES people?
Thank You!
Jeromy
Hey Nick,
Indeed, Toshiba is now branded as Dynabook.
I have not not tried a Toshiba/Dynabook in several years, so cannot speak to the newer ones. Their laptops that I own are from 2014/2015 and still work great.
For a faster computer, I upgrade the RAM and SSD hard drive on the Dell Latitude E6230 seen in #5 above and install Windows 10.
I talk more about my latest laptop discoveries here:
https://www.emfanalysis.com/low-emf-computing/#comment-25217
I’ll probably be trying out newer laptops over the next year as well and will share what I learn.
Hope this helps,
Jeromy

Hello Jeromy,
I wanted to mention that i did get to try a Dynabook (which used to be Toshiba) Laptop. The specs are “DYNABOOK Satellite Pro C50-H-11B Intel Core i3-1005G1 / 8GB / 256GB SSD / Intel UHD Graphics”. This laptop has a power cable which connects to the “earth” of the wall plug so there was no electric field present. Even so, this laptop did cause the usual EHS symptoms for me, although i have felt worse with a Dell Inspiron 15 3000 series like you mention above. I used this dynabook at a distance of half a meter for about one hour. After i used it, it took me about 30 minutes to feel o.k. again.
I also bought an HP laptop, with which also had a power cable which connects to the “earth” of the wall plug so there was no E-field present here either (i always aim to buy a laptop with a power cable which connects to the earth of the wall plug, since i live in an apartment at a block of flats and i can’t connect/earth my devices to the earth itself as you show in your videos). Its specs are “HP 255 G8 15.6″ AMD Athlon Gold 3150U / 4GB / 128GB SSD / AMD Radeon Graphics”. I used it for about 1 hour also at a distance of about half a meter. This laptop also gave me EHS symptoms, but i think they were a little more tolerable than the Dynabook and overall i think the intensity of the EHS symptoms that i had when i used this HP model was less than the Dynabook laptop and i didn’t need as much time after i used the HP to feel o.k. again, as i did with the Dynabook.
At the moment i am using an older 2009 model HP Laptop which is more manageable to use, as far as EHS is concerned, especially if i don’t use it for a long time. I have now looked for and found refurbished Dell 6230 laptop that you mention above. i can buy it with either an i3 processor with an SSD drive or an i5 processor with an HDD drive. You mentioned above that SSD drives may be worse as far as EHS is concerned but i then saw on one of your posts that you changed your HDD and put an SSD in your laptop. So, the SSD did not create any EHS issues for you in the Dell 6230? Do you think i should but the i3 with the SSD or the i5 with the HDD? would it make a difference as far as emf is concerned?
Thank You
Jeromy
Hi Nick,
Thanks for sharing your experience.
I have an E6230 with both an SSD and HDD. I do well on both. I don’t think it’s the hard drive on these that are the issue. It’s like a combination of other things that make them better for ES people (screen, processor, case/radiated EMI, etc.).
I do fine on the i5 processor. That will give you greater speed. The HDD will likely need to be replaced soon anyway (coming up on being 10 years old). You can replace it with a SSD and should be just fine.
Let me know how things go for you.
Jeromy
Nick Graham
Hello Jeromy,
I did buy a Dell E6230. It was refurbished and seems to be in generally good condition. It came with an 128GB SSD. I thought the i5 on this laptop comes with the processor that you mentioned in your post, the 3320M at 2.6 Ghz but the one they sent me came with an i5 but it is the 3340M model at 2.7 GHz. I did check at the Dell website that this laptop came with both of these processors. I would say that it does give me ehs symptoms, but these symptoms are a little less than more modern laptops. The symptoms though are more than my current 2009 hp laptop. I am thinking of buying one more Dell E6230 since I found them at a decent price. Do you think that me purchasing an 6230 with the 3320M at 2.6 Ghz that you mention in your post would give less ehs symptoms than the 3340M at 2.7 Hhz that then sent me? or should I order something different?
Thank You.
Jeromy
Hi Nick,
I would try several of them and see if one works for you.
With you laptops and all devices, electrically sensitive people have to cherry pick to see what works for your body. What works for me may not work for you. I had to try out about 30 laptops to find the ones that work well for me.
Also know that the laptop is only part of the equation. Are you okay with it when it is not connected to the internet, but once the Ethernet is connected you have more symptoms? Then it could be the Ethernet system and/or high electric fields coming to the laptop if the system is not properly grounded:
https://www.emfanalysis.com/low-emf-internet-connection/
Here is a video where I show the EMI coming to a laptop from a fiber optic modem:

Hello thank you for the Article it’s very helpful!
I been looking to buy computer for a while now and not sure really which to choose. I’m traveling so it’s need to be fairly light and I mainly going to use it for online courses and simple takes. I’m pretty sensitive to any kind of electromagnetic field so want to buy something that it’s safe to use. I’m thinking on buying a second hand one that been renewed or something to keep it sustainable and budget friendly..
Would love to hear if here is any recommendations for reliable website to buy from and laptop brand.

Below are links to products that increase distance from your devices:
1) 16ft headset extension. A headset is can be 4 feet and this extends it another 16 feet.
Aceyoon Aux Cable 16ft 3.5mm TRRS Extension Cable Male to Female with Mic Long Audio Cable 4 Pole Headphone Extension 5m Car Aux Cord for Smartphone/Tablet/Speaker and More
2) This only works for most Androids- First install the app easytether on a computer, and then install on the phone. It costs $10. This app only needs one bar of service to work and a person can get up to 25 feet from the cell phone with cable to work on the computer. This app does not use phone data, but only “talk” so no worries about using too much data as it doesn’t use any. Additionally, wearing shielding clothing may help or being in canopy, making sure wifi is off on computer.
3) 15 ft Cord from phone to computer: The cord linked below just an example, as each phone can have a different port type to plug in. You would need to find out what the name of the port type used to plug your phone in for charging. Then the other end is a USB 2.0 A or a USB-C, whichever your computer takes. Then look up those specifications on the web to find a 15ft cord. Better quality cord helps in the long run.
Though there are longer cords than 15 ft, this cord shouldn’t be longer or the reception won’t be predictably good.
Monoprice 15-Feet USB 2.0 A Male to Micro 5pin Male 28/24AWG Cable with Ferrite Core (Gold Plated), White (10864
4) Extension for mouse and keyboard (I’m not putting links here, but these extensions for an added mouse and keyboard, not the laptop mouse and keyboard.) Again, make sure the connections on the cords meet your needs. Here’s the one I used.
10FT USB 3.0 Extension Cable Type A Male to Female Extension Cord AINOPE High Data Transfer Compatible with USB Keyboard, Flash Drive, Hard Drive

The problem with cell phones, and wifi is the it creates the free radical
peroxynitrate.
For people without Salicylate intolerance, rosemary oil can knock out

Hi Jeromy,
This is a great article for a non-ES sufferer to better understand what can be done to improve the work environment.
I am seeking some specific advice on purchasing a new desktop computer for a member of staff who needs to work from a computer for up to 7 hours a day, using Microsoft software, including the capability to run Microsoft Teams (with two-way video feed). The staff member finds it easier to work on a desktop rather than a laptop as it allows distance from the hard drive.
Can anyone make any recommendations on low EMF desktop models and low EMF monitors with decent processing power?
I am keen to provide a low EMF working environment.
Thanks,
Suzy
Jeromy
Hi Suzy,
Thank you for the kudos on the article.
Here is a Dell desktop that a lot of my ES clients get:
Dell – OptiPlex Desktop – Intel Core i5 – 8GB Memory – 500GB Hard Drive – Black
Model:OP3060MTVKXV1
SKU:6260201
Also, here are some flicker-free monitors. The flicker tends to be a significant problem for people:
Samsung Low Flicker Monitor: Samsung Model S32F351FU
https://amzn.to/2LyCx8e
And this one: https://amzn.to/2Xl2En6
Creating distance, having wired computer connections, eliminating as much wireless as possible in your office and allowing people to cherry pick the equipment that works best for them is the healthiest way to go in your office.
Thank you for doing this for your staff!

Hi Jeromy, do you have any additional advice for parents whose kids are in public school and surrounded by EMFs? At home we use hardwired desktop computers (no wifi) and my kids have been homeschooled for the past two years due to the pandemic so their EMF exposure has been limited. We are preparing to send them back to school next year but I am very concerned about the increase in EMFs. They will be required to use Chromebooks connected via WiFi throughout the day.
I am very sensitive to EMFs, particularly RF (I’ve discovered this using the Tri-Field EMF meter) so I am worried about their exposure to RF the most, although electric field and magnetic field are also a concern.
Any suggestions beyond what’s been discussed here already would be much appreciated!
Thanks,
Heather
George Staggidis
Hello Jeromy,
Based on your suggestion to test keyboards and mice with an AM radio, i have tested 3 models so far but all of them seem to show high EMF on the radio. As you recommend some laptops, could you please suggest some keyboards and mice which are low-EMF?
Thank You.
Jeromy
Hi George,
Thanks for your comment. I shared the following in another comment reply. This will help you as well.
Note that the EMI may not be coming from the the keyboard/mouse. It could be coming from the laptop / Ethernet connection. Is the EMI there when the laptop is not connected via Ethernet?
I currently use a basic wired Microsoft keyboard and mouse that I got for $10. They work just fine for me.
The main issue is that the Ethernet connection is properly grounded before your laptop. That will eliminate the low-frequency electric fields, which are the hardest on me. I like to work with readings below 2-3 V/m at my computer. If things are not grounded, they can be 100 – 200 V/m.
So, do this: https://www.emfanalysis.com/low-emf-internet-connection/
There will also be the high frequency EMI. That can be eliminated by putting a fiber optic break between your laptop and the modem. I’ll post an article about that soon.
This video shows what I mean here: https://www.youtube.com/watch?v=A0PPpdT5OKE

Hi Jeromy,
Thank you so much for creating this incredible helpful blog and EMF prevention resource. In the past I have followed your advice on several purchases and been far better off for it.
One of those purchases was the specific external keyboard you recommended/linked, made by GMYLE. Unfortunately, it appears that this keyboard is no longer being manufactured/sold, and my keyboard just broke (fell while attached and the wire split/ copper severed). Do you have any other external keyboard you’ve tested to show low EMF?
Thank you so much again for all your helpful advice.

Thanks for the helpful feedback!
I do most of my writing using an ONYX Boox Note 2 E-Ink Android Tablet, used in airplane mode (so internet is not a factor in my case). The tablet’s E Ink screen is very easy on the eyes, and the device overall is very low powered/ low EMF (it helps that it has a plastic back, rather than the all-too-common aluminum). The keyboard that you previously recommended rounded out the package perfectly, but I’m afraid that it appears not to be an option any more.
Would it be possible for you to share the specific wired Microsoft keyboard/ mouse that you’ve been using successfully?
Thanks again for all your great advice!
Jeromy
You are welcome, Mike.
It is the Microsoft Wired Keyboard 600. Comes with a matching mouse. It’s what I am typing on right now.

Hi Jeromy
Thank you for providing this resource, I find it really helpful.
When choosing a Dell Latitide E6230 (or any other laptop or desktop for that matter) how much does the processor speed and memory contribute to EMF’s and EHS please?
Would it be sensible to opt for an i3 processor over an i5 for example?
How much would 8MB RAM increase EMF’s over 4MB please?
I am pretty electro-sensitive but I’m looking for a machine that can perform tasks at reasonable speeds.
(I only use an ethernet connection).
Thank you
Jane
Jeromy
Hi Jane,
Thank you for the kind words. Grateful to be able to share my experience and help others.
There are some generalities with low-EMF laptops:
1.) Older
2.) Slower
3.) Smaller
4.) Dells, Toshibas and Acers work best
5.) The laptop is just one part of the picture. The quality of your internet connection and the EMF levels in your home are also important.
I have not found a big difference between a 2 GB drive and 8 GB. Nor have I found there to be a difference between most HDD and SSD’s. Having a lower process speed is probably wise, but in the end it’s really a matter of everything put together in one package and how that laptop interacts with your particular body.
I have found that I needed to try out about 30 different types of laptops to find 4-5 that work for me. Those are the devices I list above in the article. Note that I list a new one since your comment.
For a computer that is fast enough to do everything I need on the web, the Dell Latitude E6230 and E6330 are more than enough. The older Toshibas are more for writing articles, etc and using the internet in a pinch. The Dells were old corporate workhorse machines. They are powerful, but also quiet and low-EMF, fortunately for us.
If you find something new – or a combo I don’t list above – please comment here so that we can all learn from each other.
Hope this helps,
Jeromy
Jane
Thank you Jeromy, I’m grateful for your advice.
I’m also considering trying a Dell OptiPlex desktop. I guess the drawback about desktops is that they are permanently plugged in to the mains, which can be a problem for someone sensitive to the electric fields in a house.
Is the Dell OptiPlex 3060 as per the above blog entry recommended, or is the 9020 in the link mentioned in the article also recommended please?
Thank you again.
Jane
Jeromy
Hi Jane,
I would get the OptiPlex that you can find online. It may be that 3060 is harder to find. The newer one is probably only slightly different. As a desktop computer can be placed 10 feet from your body, it’s not as big of a deal as it is with a laptop next to your body.
And, yes, electric fields can be trickier with a desktop and monitor that is plugged into your electrical wiring. It’s not impossible though and each situation is different.
I always use a laptop on battery power that has a ground Ethernet connection. In an article I will share in the next month, I’ll show you an even better way to connect your laptop – with no electric fields or higher frequency EMI. If you email me, I’ll send you the you the draft.
Sending my best,
Jeromy

Hello Jeromy!
I see that in your newer recommendations for laptops you are recommending a Lenovo Chromebook (2022). I noticed that this laptop/chromebook does not have an Ethernet port, so as you mentioned the only way here is to use a usb to ethernet adaptor. Do usb to ethernet adaptors give out emi/emf? Besides the one from electrahealth which would be difficult to buy for us living outside the US (customs, extra fees etc), are there any other usb to ethernet adaptors which may give out low EMI/EMF? Thank you!
Jeromy
Hi Nick,
Great question.
I am actually going to post an article on Ethernet adapters soon. Many do indeed create high electric fields and additional EMI.
Most of the adapters I recommend do indeed come from the US. If you test a few that are local to your country, please let me know the results.
Hope this helps,
Jeromy
George Staggidis
Good Afternoon Jeromy,
I read that your recommendation for laptops is to use them on battery without their charger and use earthing for the ethernet plug. Your earthing is safe because you are on the ground floor and able to earth the ethernet plug on the ground itself. However, many of us live on apartments on certain floors, maybe 3rd floor or higher. So, in this case, how should we earth the ethernet plug?
Perhaps through the power plug earth metallic pieces(s) on the wall power plug or is there somewhere better where we can earth? I am asking this because, the earthing on a block of flats sometimes does carry EMI/EMF itself so some people say it should be avoided, particularly when it comes to using earthing products directly on one’s body.
I have personally tried an earthing mat which i connected to the earth power plug on my apartment which is on the third floor of a block of flats – every device i placed on it became earthed indeed and produced 0 E-Field or a very very low E-Field, however, when i placed my hands on the earthing mat, i did not feel well and had to stop. i should mention that when i earth on most grounds like in nature etc it generally makes me feel well/better. (some grounds in cities however or other places have emf because there is something near there, like power cables, which produces them so it is not good to earth there).
Does earthing devices like laptops maybe differ from earthing products because perhaps you do not essentially come in direct contact with the earthing itself, as you merely touch the plastic for example on a laptop’s keyboard and thus is earthing your laptop through an earthed wall plug beneficial?
Also, if we buy a laptop which has a charger which does itself have an earth pin on its plug, when we connect this to the wall plug, the laptop is then grounded (so there is 0 E-field present), so, would you say that it would be good to use a laptop (which has an earth pin on its plug) plugged on the wall so the earthing happens like that (and that eliminates the need to earth the ethernet plug), Or using a laptop charger connected to the wall plug, even if it does have an earth pin on its plug and thus having/producing 0 E-field, produces EMI anyway through the charger/connection to the power plug, so it should be used on battery anyway and earthed in another way without using its charger which has an earth pin?
In a few words, is it worth buying a laptop which has a charger which has an earth pin, or does that not matter because a laptop should always be used without its charger even if that charger has an earth pin?
Thank You.

Hi Jeromy,
If you find a way to power your computer set up through a UPS/power bank all the time, is it safe to say that the emissions from the computer set up will be negligible? And that too, without any grounding.
If yes, do you get UPS/power banks of such power? As I read that most of them would last you not more than an hour?
Note: Please assume everything wireless is switched off and please disregard the EMI from the ethernet wire for the purpose of this question.
Jeromy
Hi Yash,
I always use a laptop that is run on its own battery. I just buy new long-life batteries for my laptops every couple of years.

My question is about Australia.
My suburb (Westmead) in Sydney) has gone into NBN, so ADSL is no longer supported.
Which is the best router/modem that I can purchase?
a) Which does not have Wifi at all preferably? If all router/modems have WiFi, I’d prefer it only operates at 2.4 GHZ single band and doesn’t work at 5.0 GHZ at all.
b) Which has a Wifi on/off button?
c) Which has multiple ethernet port connectibility?
d) Doesn’t throw too much EMI?
Jeromy
Hi Yash,
You will need to use a modem that integrates with the NBN system in Australia. They may have a list of 3rd party modems, like the cable internet companies do in the US. If you have fiber to the home, you will likely need to use what they provide, but you should be able to disable the WiFi.
For a router, most of my clients get the JRS eco-router:
https://www.jrseco.com/p/jrs-eco-100-wifi-d2-on-asus?c=6680
The AC1900 only has the WiFi on when a device is connecting to it. Then it radiates at 90% less power than other routers. It also has an “on/off” button for WiFi so it can be completely turned off (only this JRS “D2” model has this button). The speeds of this router are very high ~ up to 400 mbps for WiFi and over a gigabit for wired connections.
JRS offers my clients a discount of $8.50 on any purchase. You will enter this code at checkout: JJ21FHRE

Revisiting your website after having to get a new computer system (old 2010 iMac won’t work for my needs anymore).
What product would you recommend to encase a newer (2019) MacBook Pro in?
I’m going to use the MacBook as the powerhouse I need (for the software and very large files, etc), and I’m going to connect it to an external drive, separate BenQ monitor, wired keyboard and mouse, all through a docking station.
So, it will sit there, but it will be closed the whole time, as I’ll only be “using” the wired mouse/keyboard and separate monitor. So is there some sort of casing I can put the closed MacBook in so it doesn’t emit anything?
(not sure if I’m explaining my soon-to-be set up well or not!)
Jeromy
Hi Megan,
Great question.
The best answer is going to be creating distance between you and the MacBook Pro.
When I worked in Silicon Valley, I had my laptop docking station about 7-8 feet from me on the floor beyond my desk. This worked great for me. Then I just had the monitor, keyboard and mouse to contend with.
Do you have the space to do this?
I don’t know of any good products for this type of shielding. LessEMF used to have a laptop case shield that you could put over the closed laptop or over the keyboard/processor. However, I don’t see it on their new website yet. They are in the process of adding in all of their products.
If you create distance, then it will just be a matter of the electric field and EMI coming to your keyboard. I’ll be sending out some new articles on how to reduce this soon.
Hope this helps,
Jeromy
Megan
Thank you for replying!
Unfortunately I don’t have that kind of layout in my room to put that far away. I’m hoping to put little covers on any of the components that are high EMF to block out what I need when things are on during the day.
Was this the sort of product you mean: https://lessemf.com/product/ipad-pouch/
Except this one would just be a little too small for the new laptop (16″ diagonal).
Or, was there some entirely different product you were thinking of?
David Richard
Is it safe to assume that the emissions from your computer setup will be minimal if you can power it continuously with a UPS or power bank, and that too without any grounding? I read that most of them wouldn’t last you more than an hour, so if that’s the case, do you have any UPSes or power banks with such power?
Jeromy
Hi David,
I’ll be sending out an article soon about a low-EMF laptop setup using a DC power bank.
Stay tuned.
Jeromy
Yash Rungta
Hi Jeromy,
I have set up my laptop 1 metre away. A bulk of the EMF fields from the laptop die down in this distance. However, the wired keyboard and mouse are carrying a lot of EMF with them which can be picked by my radio R9012 that you recommend.
What is the best way to set up my wired keyboard and wired old fashioned ball mouse to eradicate this issue? I’m beginning to think that a wireless keyboard and mouse might well be less worse i.e. the lesser evil.
Does using a powered USB hub that runs on 5V DC which is being powered by a power bank solve this issue?
Eric
My Dell e6330 as well as my other laptops are pulsing very high RF….I had not previously noticed this before. I tried disabling the adapter/driver that emits wifi and still no reduction. I’m kind of freaking out because 1. The new area I moved to is putting my computers in a frenzy (5G, fiber optic required modem) or 2. I somehow never noticed it was so high. Thanks
Jeromy
Hi Eric,
The Dell laptops have a physical Wi-Fi button on the right side of the case. You will also put them on Airplane mode. That will turn off all the wireless components.
You can always send me a video showing the RF coming from your laptop via email. See my contact form above.
Hope this helps,
Jeromy
Lisa
Hi Jeromy,
What about magnetic and electric fields on keyboards, mouses and laptops? My devices measure low for RF and electric fields, but high magnetic fields. Do you have a recommendation?
Thanks,
Lisa
Jeromy
Hi Lisa,
Laptops will have a magnetic field within inches of the processor, but that’s about it. Nothing to worry about as you are several feet from the laptop.
If you are measuring a magnetic field at your keyboard/mouse, that tells me there is a magnetic field issue in your office/home. That’s an ambient field as the keyboard should have no magnetic field.
What EMF meter are you using to measure all of this. Most cheaper 3-in-1 meters really aren’t giving you readings you can trust. Typically it’s electric field and EMI from your wired Ethernet connection that are causing the most issues. This can be completely eliminate though.
Happy to discuss and provide specific feedback for your situation via email or a Zoom consult. This is how I work:

Hi Jeromy,
I am using the Trifield Meter. I found that an air purifier near where my desk has a high magnetic field. I’ve disabled it and notice that I feel much better at the end of the work day. I knew that something was zapping my energy while I worked.

Thanks for sharing this Lisa. Wonderful that you figured this out!
Simply moving the device away from you is all that needs to be done.

Hi Jeromy,
Can computer monitors, TV screens and screens of other electrical appliances like cell phone, tablet etc. not be based on the incandescent light technology rather than say LED/Plasma/CRT etc.? This will not only reduce the EMI from the screens by probably 90-95% and will also be more pleasant to the eyes.
Are there any such monitors available? This could potentially solve the problems with computer setups for a bulk of the EHS population. It could be a game changer.
EDIT: Look at this:
https://forums.tomshardware.com/…/incandescent-light…/
Some people have modified their monitors to use incandescent light!
Nick Graham
Hello Jeromy,
As far as using external keyboard and mouse with laptop, I have tried 4 different keyboards and mice but they all create electrical sensitivity symptoms for me. I have to mention that my laptop is earthed through its charger which I have connected to the laptop because it is a 3-prong earthed plug so it earths any E-field coming from the router connected through ethernet.
Some keyboards and mice create more issues than others. Even when the voltage mentioned on the keyboard or mouse is low like 25mA in specific for one mouse and keyboard I tried, this one still creates EHS problems for me. I can’t use it at all. Then again, I can’t use the one you are using the Microsoft 600 keyboard and mouse you mention, they create big problems for me and can’t use them for more than 10 minutes. After that I get EHS symptoms and have to unplug them.
This Microsoft mouse mentions 100mA voltage. Having tried 4 keyboards and mice, ALL of which give off lots of EMF which I found using an AM/FM radio, what other solution is there?
Have you or anyone found a keyboard and mouse which give off low EMF when using an AM/FM radio to detect?
Thank You.
Jeromy
Hi Nick,
Thanks for your questions.
A few key points about your setup:
1.) The keyboard and mouse is perhaps 5% of the low-EMF computing issue.
2.) Plugging in your laptop to a grounded AC outlet doesn’t get rid of the AC electric fields.
3.) Don’t worry about the mA of your devices.
4.) The AM radio is not meant to be used in this way.
The following is how I recommend you approach low-EMF computing:
1.) Make sure you are working in a low-EMF environment where all four types of fields are low.
2.) Cherry pick a laptop that you can use without symptoms for a couple hours while not connected to the internet or AC power. This is your baseline. If you can’t work on a computer like this, then it’s not the laptop for you.
3.) Use that laptop only on battery power that sits at a distance with your basic wired keyboard and mouse.
4.) Connect your laptop to the internet via a fiber optic setup that is not connected to AC power.
This is what I have done and have very little sensitivity to my computing anymore.
I can walk you through all of this in an email consultation. You can find this option here:
https://www.emfanalysis.com/work-with-me/
Hope this helps,
Jeromy
Nick Graham
Hi Jeromy,
Thank you for your reply. Just a couple of points. You say that “Plugging in your laptop to a grounded AC outlet doesn’t get rid of the AC electric fields”.
But, For example, when I connect a router/modem which i have measured with an e-field meter Gigahertz 3030B to give off around 1000V/m to 1200V/m E-field in close proximity to it, then if I connect my laptop to this router/modem with an ethernet cable then my laptop also emits 1000V/m E-field close around it.
However, when I connect the Grounded (3-prong) charger (the grounded AC outlet) of the laptop to the laptop and the wall socket, the E-field meter then shows only around 1 to 8V/m around the laptop. This is an almost 100% reduction in the E-field. So, doesn’t that mean that the grounded charger got rid of most if not all of the E-field?
You also say “Cherry pick a laptop that you can use without symptoms for a couple hours while not connected to the internet or AC power.” You mean use the laptop for a couple of hours with my hands on the laptop, or use the laptop for a couple of hours with an external keyboard and mouse?
Thank You!
Yash Rungta
Hi Jeromy,
What is the best way to monitor EMFs from laptops? I have a few old laptops and I would like to measure EMFs? Are electric fields the major component? I have a ME3830B for measuring EFs and MFs. I have a radio to measure EMI/DE through the air. I have a Cornet meter to measure RF.
Also should we measure EMFs near the laptop or near the external wired keyboard and wired non optical mouse that we attach?
I understand that feeling the laptops for a few hours is the best. But it’s always good to be able to measure and get a reading.
Wolfgang
Hi, thank you for all the useful information. I actually bought a low EMF laptop today after visiting several stores in my area (close to Miami) with a Trifield TF2 meter…
I tried to check every laptop that was on display in those stores (Best Buy, Walmart Superstore, Target Superstore). I’ve found that the newest Apple Macbook Air was pretty good and all new Samsung tablets.
Then I found one computer that I did not expect to be that good. I’ve actually checked it several times because I thought that I made a mistake and that it could not be so low, especially in comparison to all those other laptops. I ended up buying it and also at home it shows almost zero EMF.
It’s actually a gaming computer: MSI GF63 Thin 15.6″ Gaming Laptop, 144Hz FHD, Intel Core i5-11400H
Jeromy
Thanks Wolfgang.
Let us know how this works out for you.
The TriField isn’t really the EMF meter for measuring laptops. The issue with laptops are the mid-frequency fields generated by the processing equipment and screen. These frequencies won’t be picked up by the TriField.
The other issue are the electric fields and EMI being transmitted to the laptop via the Ethernet system. These are amplified by aluminum cases like Macbooks.
Macbooks are typically not tolerated well by electrically sensitive people at all, even if they measure hardly anything with the TriField.
The best thing is to cherry pick laptops by trying out several and keeping the one that doesn’t give you a headache after hours or days of use.
Thanks again for writing.
Jeromy
