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, burning skin, chest pain, heart arrhythmia or other EHS 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.
Using a computer has often been a struggle for me since becoming electrically sensitive four years ago. I can have periods of high sensitivity that last for for weeks or months. During these times, being on a computer just 30 minutes a day can be a challenge for me.
However, through this process I have learned a lot about what works, and what does not when it comes to using a computer safely. My hope is that you can implement some of the solutions below to get back online or to simply prevent you and your family from experiencing the negative effects of EMFs.
Here are ten of 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. 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.
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, which is a newer model than the 3000 that I have (Note: Get the Neo, rather than the Neo2). 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 by the phone. Then, put the phone down on a table, turn off Airplane mode and walk away from the phone. Within a couple minutes, 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.
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 EHS symptoms. There is something about the newer, more powerful computer processors (especially solid state hard drives) 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 EHS.
Low(er) EMF laptop computers (current suggestions February 2020):
Toshiba Satellite Laptop (Purchased 2015 & 2018 – exact model number is C55-B5299). This computer has minimal computing power, but works great for internet and word processing use. It is one of the few new computers I have tested where my headaches are manageable (likely due to the lower processing power). The faster model (4 gig of Ram) is model number C55-B5298 is also a low-EMF laptop that works well for me. You will have to shop around to find an available unit to purchase (they sometimes come up on ebay, Walmart or Amazon).- 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 1-2 hours at a time. You will have to shop around to find an available one to purchase (typically ebay, Walmart or Amazon).
- Acer Aspire V5 11.6″ Laptop (Recommended by ES colleague 2019). Small, lightweight, good speed. This laptop works very well for me. I have the 4GB Ram model and moved it to Windows 10 for a bit more speed.
- Toshiba Satellite Laptop (Purchased 2017) – Model number L755-S5365 from 2012. I recently purchased this laptop via ebay on the recommendation of another ES person. So far so good with this laptop. My colleague swapped out some of the hardware and software in this laptop to make it very quiet (processing speed of less than 1 GHz).
- Dell Latitude E6510 Laptop (Purchased 2012) – An excellent computer with ample processing power that is very quiet and causes minimal symptoms for me.
- Many desktop computers (or laptops connected to a docking station) with separate monitors can also work well (Dell monitors from 2010-2011 work 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).
The following are computers that I have reacted to very quickly (usually headaches and pressure in the chest within 10-20 minutes). I returned these computers 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 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. 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.
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, as well as my AlphaSmart. Every computer emits its own set of frequencies. By changing things often, it will help your body from becoming sensitized to any one computer.
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.
8.) Use a Low-EMI 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). Here is a short video where I demonstrate how you can test your keyboard. This wired keyboard has been tested to be low-EMI.
9.) Wire Your Smart Phone. An electrically sensitive colleague recently shared how she uses her smart phone for emails 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 smart phone then acts like a small computer screen (which is better than a normal computer screen for most 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.
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 that was 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, but he now has an ultra-low EMF computer setup. His knowledge is extremely valuable and could help you if you are serious about building such a system.
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. If a system like this is of interest to you, please contact me and I will connect you either to Bruce or another colleague, Richard Conrad, Ph.D, who also has considerable experience helping people design and build low-EMF systems.
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.
The following video was recently shared with me as well. This is what one man invented to create an ultra-low-EMF computing solution:
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.

sara faith
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

If you are EMF sensitive then you would never use computer WiFi and be around a router. Just saying.
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?
Tara T
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:
http://www.emfanalysis.com/safe-computing/
Thanks for pointing this out.

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
Mary Anne Tierney, RN, MPH, Fairview NC
Jeromy
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.
Jeromy
Bill Bruno
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.

I hope you incorporate these helpful solutions by Commenters into some of your “Solutions” articles – all these people experiencing what works is such a wonderful sharing! Thanks to all Commenters and Jeromy!
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
Nandan
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.
Peter
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.
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:

All my best,

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.

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

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:

Penny Johnson
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
Jeromy
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.
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,
Jeromy
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
Connie
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!
Connie
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
Maddie
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…
Jeromy
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:
https://www.emfanalysis.com/recommended-emf-meters/
Keep in touch,
Jeromy
Ran
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.
Jeromy
Judy
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.

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,

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.”

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.”

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?
