EMF Field Guides: The Beginner’s Guide to


23 Common EMF Sources Found Throughout Homes

In this EMF field guide, we’ll show you 23 common sources of EMFs found in homes.

Some of these you’ll have heard of, but we bet several are going to be new to you.

Being aware of these is a big first step in lowering your EMF exposure today.

Let’s get started:

23 man-made EMF sources commonly found in homes

The following are some of the more commonplace, man-made EMF sources people come into contact with within their homes.

Thankfully, the exposure levels of many of these can be reduced or eliminated by simple lifestyle changes and without much effort.

To read this material off-line, PDFs and eReader (Kindle, etc…) versions of this EMF Field Guide and The Beginner’s Guide to EMFs are available, as well.

Wi-fi Systems and Components

These are the products that produce and amplify your wireless internet.

We’ve also included security systems, as a great deal of homes have these products and have them operational 24/7.


Wi-Fi Routers

We mentioned routers in the Top 20 list already, but wanted to reiterate the significance of wi-fi as 24/7 source of radio frequency radiation.

At a minimum, if there isn’t a medical or security necessity, try and turn these off at night when everyone is sleeping.

In the situations where this isn’t possible (wireless security systems, for example), and it’s safe to do so, there are ways to lower the output of the wireless routers through shielding devices.

A Low EMF Solution

Turning off your Wi-Fi can be achieved by the following means:

A – Some internet providers that have a wireless router bundled with their service modem have apps that you can use to remotely turn the wireless router on and off.

B – Put your wireless router on a mechanical timer that you plug into your electrical outlet. This will turn it off every day at a selected time.

C – Utilize a remote IR kill switch. Right before you go to bed, you can turn off your wireless router with the click of a button and then turn it back on when you wake up.


Wi-Fi Hotspots

Some internet providers (Comcast is one) have some router models that allow the routers to be used as a “Public Wi-fi hotspot.”

What this means is that anyone in the area that subscribes to their service can connect to the internet through your router. You may have substantially higher RF exposure as a result.

We recommend researching your provider and router model to make sure this isn’t the case. If it is, there are ways of turning this off.

Please read our guide on How to Turn Off Your Residential Wi-fi Hotspot. (coming soon)

A Low EMF Solution

The solution is to turn this option off.

Wi-fi Extenders and Boosters

Just a reminder that these produce radio frequency radiation similar to wi-fi routers.

And, as with wi-fi routers, it’s best to get rid of them entirely if you want a low EMF home. Hardwire your internet instead.

Heaters of all sorts can produce elevated magnetic fields. Some examples of these:

– Ceiling Heaters
– In-Floor Heating
– Baseboard Heaters
– Radiators

You can read more about these below.

We also have a guide on How to Choose a Low EMF Home or Apartment. (coming soon)


Ceiling and In-Floor Heaters

Ceiling and floor heaters can be especially problematic as there often isn’t an easy way to achieve distance from these heating sources.

This is something to be aware of when choosing an apartment or condo in a complex that utilizes this type of heating. If you’re in a unit that’s above a ceiling heater, you may be subjected to elevated magnetic fields from it.

A Low EMF Solution

When selecting a home or apartment, or simply where to place your bed or couches in various rooms, keep the types of heaters and the locations in mind.

Use a gaussmeter to survey for the AC magnetic fields or call an EMF consultant.


Radiators & Baseboard Heaters

These are often on one end of the room which provides the opportunity to place beds and couches a greater distance away.

Take advantage of this opportunity and distance the spots you frequent the most from these sources of heat.

A Low EMF Solution

When selecting a home or apartment, or simply where to place your bed or couches in various rooms, keep the types of heaters and the locations in mind.

Use a gaussmeter to survey for the AC magnetic fields or call an EMF consultant.


Portable Heaters

The portability of these heaters makes the mitigation of their magnetic fields easier. Using a guassmeter, you can move it back far enough to safely reduce the field exposure.

A Low EMF Solution

When selecting a home or apartment, or simply where to place your bed or couches in various rooms, keep the types of heaters and the locations in mind.

Use a gaussmeter to survey for the AC magnetic fields or call an EMF consultant.


Breaker Boxes

Breaker Boxes are common sources of elevated magnetic fields. If these are adjacent to bedrooms and living areas, it’s a good idea to increase the distance between beds and sitting areas and the boxes.

These can also be shielded with some degree of success. Our guide on AC magnetic field shielding will be coming soon.

A Low EMF Solution

The best solutions is to just increase the distance of beds and couches from the breaker boxes. Shielding is also an option.


Wiring Errors

Wiring errors due to improperly conjoined electrical circuits can produce sizeable magnetic fields.

Thankfully, these can be sussed out with a good gaussmeter (visit our EMF Meter Reviews page) and then corrected by a certified electrician.

A Low EMF Solution

Have your home surveyed by an EMF Expert or purchase a guassmeter that and do a DIY EMF survey.

Read our page, “The Best EMF Meters of 2020.”

Location of Appliances & HVAC Systems

Any appliance or HVAC system component that has a motor, fan or condenser will have magnetic fields of varying degrees.

There are home, apartment and condo layouts where these items are directly on the other side of the wall from bedrooms and living areas. This can mean that beds, couches and other frequented areas are in the middle of elevated magnetic fields.

It’s worth surveying the areas around the following appliances and making sure you, your children or you pets aren’t spending significant time in elevated magnetic fields.


Refrigerator Location

There are home and apartment layouts where the refrigerator backs up against a shared wall with a bedroom or living area.

The sides of some refrigerator models can have extremely elevated magnetic fields. Test the adjacent areas with a gaussmeter and make sure your bed or couch isn’t directly on the other side of the wall from these models.

A Low EMF Solution

Most refrigerators can’t be moved to another location in the kitchen, so you’ll most likely need to move the bed or furniture in the adjacent room.

These magnetic fields can be reduced with shielding, as well.


Furnace Location

Similarly to refrigerators, be aware of the location of your furnace or neighbor’s furnaces in relation to your home’s frequented areas.

A Low EMF Solution

Furnaces likely can’t be moved to another location in a mechanical room, so you’ll most likely need to move the affected bed or furniture.

These magnetic fields can be reduced with shielding, as well.


Washer & Dryer Location

In apartments or condos, these can be tucked into closets adjacent to bedrooms. Just be aware of where these are.

A Low EMF Solution

Washer and dryers are likely in a permanent place, so adjust adjacent living areas accordingly.

These magnetic fields can be reduced with shielding, as well.


Electric Water Heaters

These can also be placed in odd areas that are adjacent to bedrooms. Be aware of where these are, too.

A Low EMF Solution

As with the others, these are likely in a permanent place, so adjust adjacent living areas accordingly.

These magnetic fields can be reduced with shielding, as well.


Air Conditioners

The placement of these is quite a bit more obvious.

The models that are secured into walls and window openings can often be right next to beds, so be aware.

A Low EMF Solution

Depending on which models and where these are placed, you may have some leeway on moving these. Try and keep a good distance, if possible.

Smart Home Technology

Smart home technology is all the rage these days. It feels like companies are throwing radio frequency chips into most everything and it’s something to be on the look out for.

Below are some examples of smart home technology and some ideas of where the technology is headed.


Smart Thermostats with Wi-fi

Nest, Ecobee and other smart thermostats were some of the first entrants into the smart home technology arena.

The ease of use and novelty of these devices is obvious, but all are RF emitting devices and need wi-fi to operate with the phone applications and controls.

Our recommendations for a low EMF household would be to use traditional thermostats instead.


Smart Air Conditioners

Manufacturers are starting to push these smart air conditioners, so users can control them with their smart phones.

It will put more RF radiation in your home environment and necessitates having your wi-fi on.

We recommend using standard, dumb air conditioners.


Wireless Security Systems

Wireless security systems use radio frequency waves to communicate with the base system and the monitoring company. Why not get rid of this wi-fi and cellular wavelength exposure?

Read our guide on how to have a hardwired security alarm system installed.

A Low EMF Solution

Many of the alarm monitoring companies still do hardwired installations. Click the links below to learn more from these companies. (coming soon)


Smart Door locks

These also have novel features similar to the doorbells and thermostats. They also are dependent on wi-fi and should be avoided by RF sensitive people and others striving for Low EMF environments.

These are also becoming more commonplace in travel accommodations such as hotels, AirBnB and VRBO locales.

Unfortunately, it makes it more difficult for visitors to turn off the wi-fi, due to the smart locks reliance on it.


Smart Doorbells

Smart doorbells were another early entrant on the smart home technology scene and have become increasingly popular due to their remote video and audio capabilities.

Ring, Arlo, and MyQ are some of the more prominent brands in this technology space.

As with other smart technology most of these devices will have RF transmitters and need to be hooked up to wi-fi to operate properly.

There are some models, such as the Ring Video Doorbell Elite, that can use ethernet cable to connect to the internet. This removes the need for wi-fi, but the RF chip may still be transmitting.

Contacting the manufacturer of these should help you ascertain whether the wi-fi capability can be completely turned off.

Alternatively, you can go with a normal doorbell and a video security system that doesn’t use wi-fi or cellular networks at all. Our guide on this will be coming soon.


Smart Light Bulbs & Floodlights

Smart bulbs use both wi-fi and bluetooth to connect with smart hubs which then connect with the smart phone apps used to control the bulbs.

With these you’ll effectively have an RF chip in every bulb in your home.

Most of these bulbs are LED, as well, which may contribute to extra dirty electricity on your electrical circuits, too.

We recommend going with old-school incandescent bulbs. This one has a vintage vibe.


Smart Lighting & Switches

Smart switches are used to circumvent the need to use individual smart bulbs and to help simplify the process of using smart lighting.

While it’s surely better than having every bulb emitting RF fields, a Low EMF home is better off without these.

Instead of remotely turning the lighting on and off, we recommend doing what our parents did and asking your children to get up off the couch and do it.


Smart Garage Openers

Smart garage door openers are another smart home application used primarily with smart phones and wi-fi.

As you may have guessed by now, we recommend going with old remote-control models that either don’t have wi-fi or where it can be turned off.


Smart Kitchen Appliances

These are also becoming increasingly popular and can also be found in garages, bedrooms and dorm rooms.

Please see our chapter on Common EMFs in Kitchens to learn more.


Smart Laundry Appliances

Unlike some of the smart home technology, I’m not really sure why smart washing machines and dryers are desirable.

Regardless, be aware that they’ll have RF chips within them and wi-fi will be needed to operate these “smart” capabilities.

A Low EMF Solution

As mentioned in most of the descriptions above, all of these utilize bluetooth or wi-fi. It will come as no surprise that the low EMF solution is most often to get rid of or don’t purchase SMART home accessories.
