Computer & Tech Devices That Cause EMFs in Home Offices

14 Common EMF Sources Found
in Home Offices

This section is a compilation of common EMF sources found in living rooms, TV rooms and home offices.

These are areas where people spend a lot of time, especially in the evenings, and can be littered with many different RF producing tech devices.

With all our sections, we’ve included a recommended solution for most of these. Some of these outbound links may be affiliate links to help our mission of EMF education.


Computer Monitors

These can sometimes have elevated AC electric and AC magnetic fields.

TCO Certified, an organization out of Sweden, does sustainability testing for IT products. This testing includes some AC electric and AC magnetic testing for monitors and other devices.

Using their product search is a good place to start in a search for computer monitors. After shortlisting some models, we recommend testing them with a gaussmeter and electric field meter before purchasing.

The new LCD and LED monitors won’t have elevated fields to the extent of the old CRT monitors, but we recommend playing it safe and not being right on top of the monitor.


A Low EMF Solution

Use the TCO Certified product finder and then test in-store if possible, before purchasing a new computer monitor.

Computer Peripherals

Recently, there’s been a big computer industry push towards wireless computer peripherals. Below are some of the more common options.


Wireless Mouse

A wireless mouse most commonly communicate with bluetooth RF radiation.

We recommend using a wired mouse instead.


Wireless Keyboard

Like a wireless mouse, wireless keyboards communicate with bluetooth. This is unnecessary RF radiation.

Use a wired keyboard instead.


Wireless Headphones

Wireless headphones look cool, but they hit you with RF fields and AC magnetic fields from the speakers. Both are directly adjacent to your head and brain and are worn for long periods of time.

Get a pair of wired, airtube headphones instead. These will eliminate the RF radiation from bluetooth and greatly reduce AC magnetic exposure.


Wireless Speakers

These can be large sources of RF radiation and the exposure times are often long.

We recommend getting a wired speaker system that you can plug your phone or stereo into.


Wireless Printers & Scanners

As with most other products, being wireless means that there will be radio frequency field exposure.

Most printers can be accessed with USB or ethernet cords and we recommend doing so. Don’t forget to turn off the wireless functionality on the printers or scanners.


Wireless Projectors

These will have radio frequency fields and possible AC magnetic fields, too.  We recommend getting a projector model that you can hardwire with ethernet cable and turn off the wifi or bluetooth functionality.

A Low EMF Solution

Find equipment models where you can turn off the wifi and bluetooth and use cables to connect to.


Office Copiers

Office copiers run frequently and can produce elevated magnetic fields and RF fields if connected to wirelessly.

For the AC magnetic fields, try and make sure that you’re not seated next to these for long periods of time. The RF fields can be mitigated by hardwiring these and turning off the wireless and bluetooth functionality.

A Low EMF Solution

Hardwire and distance, distance, distance.


Desktop Cooling Fans

As with most fans these will produce magnetic fields. Make sure and put these a safe distance away from where you sit. You can test with a gaussmeter to be certain.

A Low EMF Solution

Make sure these aren’t right next to you.

Under Desk Computer Components & Chargers

Below are a list of additional items found under desks or in home offices.


Surge Protectors & Battery Backups

These can subject you to elevated AC magnetic and electric fields. We recommend you move these out from under your desk and as far away from your seated position as possible.

The cords from these devices can also be responsible for elevated AC electric fields. Wrapping them in conductive tubing can help lower these.


Power Strips

These are often found adjacent to where people sit for long periods of time. Try to create space between these and


Computer Speakers & Subwoofers

Computer speakers and subwoofers are often in close proximity to the computer users. These can produce elevated electric and magnetic fields (and perhaps RF fields, too, if they utilize wireless or bluetooth functionality).

We recommend that you stick with wired models and create as much distance as you can between you and these components.


Wired and Wireless Chargers

These cords will often emit elevated electric fields. Put these on the other side of the home office from you, if possible.

You can test these with an electric field meter.

A Low EMF Solution

With many of these items that are commonly under or close to where people sit, distance is the key.


Laptop Computers

Ungrounded laptops can give off elevated AC electric fields and components inside the computers (hard drives, etc…) can produce AC magnetic fields.

A low-EMF laptop recommendation would be to connect your laptop with a wired keyboard and mouse and a low-EMF monitor, keeping the computer and monitor at a safe distance.
