The Ultimate Guide to Buying an EMF Meter [Updated 2023]

Are you confused about electromagnetic field (EMF) exposure and its potential effects on you, your home, and your family? 

Or do you want to buy an EMF meter but don’t understand the technical specifications and uses?

Yes? Great, you’re in the right place! 

In this guide, we will cover: 

  • What are EMFs? 
  • The health risks and symptoms associated with them
  • EMF meters you can use to detect levels of EMFs in your environment 
  • Ways to protect from those EMFs

First things first

Like many, you probably already know that EMFs are not harmless. And with the World Bank estimating that over 90% of the global population is exposed to electricity, even if you do not live in a crowded city, they are likely an issue in your everyday life.

We should also note that over 80% of the countries surveyed by the World Health Organization set limits on EMF exposure, so the concerns are well-known.

However, the myths and misinformation surrounding EMF exposure make it difficult to separate what is false from the reliable information and valid concerns.

EMF Protection is committed to providing accurate and up-to-date information so you can protect yourself and your loved ones from EMFs and live well in the electromagnetic world in which we now live. 

Understanding EMFs

EMF refers to electric, magnetic, and electromagnetic fields. These fields create transmission wavelengths that carry radiant energy, so they are a source of radiation. These transmission waves include radio waves, light waves, gamma rays, and X-rays.


Your home’s electrical wires and your wireless devices produce EMFs all around you. In addition, the power lines and cell phone towers in your neighborhood constantly emit EMF energy. All this exposes you to a certain type of EMF radiation.

EMF Radiation Types

There are two types of radiation: non-ionizing and ionizing.

Non-ionizing is low to mid-frequency and the more prevalent type. EMF meters mostly measure EMF from non-ionized radiation sources.

These sources can be:

  • Power lines
  • Radar and satellite
  • Cell phones and cell phone towers
  • Computers and televisions
  • WiFi networks and devices
  • Bluetooth devices
  • House electricity wiring
  • Home smart meters
  • Airport scanners
  • Microwave ovens
  • Motion detectors
  • Magnetic Resonance Imaging (MRI) devices
  • LED, incandescent, and compact fluorescent light bulbs
  • UV from blacklights, sun lamps, and tanning beds


Increasingly, we encounter non-ionized EMF radiation routinely from multiple sources, more so than even 50 years ago. (Because of this, it is critical that scientists and health officials continuously research potential health effects as our non-ionized EMF exposure steadily increases.)

Ionized EMF radiation is less prevalent but more intense. This EMF radiation is in the mid-high frequency range, and its sources include:

  • UV from sunlight
  • X-rays in hospitals and airports
  • Radiotherapy
  • CT scanners
  • Certain gamma rays, like nuclear energy

Aside from sunlight or particular careers that heighten your exposure, your contact with ionized EMF radiation should be lower and more controlled.

Because ionized EMF radiation exposure intensity is higher and over a shorter time period than non-ionized, it has already been conclusively linked to adverse health effects.

The Health Risks of EMF Radiation

Ionized EMF exposure health risks are well known. Ionizing radiation has many adverse reactions, including acute radiation sickness, cancer, and birth defects.

However, similar to the history of tobacco and asbestos, the current debate about non-ionized EMF radiation exposure and its effects on our health is based on competing interests.

While scientific research suggests links between non-ionized EMF exposure and adverse health effects, these are difficult to research conclusively for many important reasons, including:

  1. Our current level of EMF exposure is relatively new.
  2. The EMF radiation is low intensity, and the radiation exposure is over a long period of time.
  3. Exact EMF exposure is difficult to monitor.
  4. A sufficient control group not exposed to EMF radiation is difficult to find.
  5. The research conditions and outcomes are difficult to replicate.
  6. Too many other correlating factors can also cause similar health risks, including chemical and bacterial exposure.

The International Agency for Research on Cancer (IARC) lists EMF radio-frequency radiation as a possible carcinogen. (Carcinogens are any substances that can cause cancer.)

Other studies have found possible links between non-ionized EMF radiation and adverse neurological, psychological, cognitive, and nervous system effects.

While not conclusive yet, they indicate EMF exposure concerns should be researched further and not completely dismissed. 

EMF Protection has a wide range of tried and tested EMF solutions to help you Detect, Protect and Sleep in the increasingly wireless world in which we now live.

And with our guarantee, you can have FULL confidence.

Your health is too valuable to settle for gimmicks & placebos.

5G Networks

There are also scientific concerns regarding 5G networks

Several factors mean that 5G increases environmental EMF exposure:

  • 5G uses new and previously unused radio frequencies. 
  • It uses more direct signals of greater strength.
  • Although 5G utilizes smaller towers, it requires more per area to boost signals. 
  • The networks are adding antennas and ports to existing towers.

While many conspiracy theories exist about 5G – including that they transmit COVID (they don’t) or that China and Bill Gates are using 5G signals to manipulate or spy on people (probably not) – these wild theories should not detract from legitimate health concerns.


Electromagnetic Hypersensitivity (EHS or EMS)

Debates around EMS continue due to the lack of diagnostic testing. However, the National Center for Biotechnology Information (NCBI) has determined that EMS is “biologically plausible.” 

People across multiple countries have independently reported symptoms of EMS, including headaches, tingling, and dizziness. More severe symptoms include fatigue, lowered concentration, nausea, heart and digestive irregularities, sleep and mood disorders, and musculoskeletal pain.

Although research has not yet conclusively proven EMS exists, neither has it conclusively debunked it. 

Interestingly, the rise in EMS reporting correlates with the increasing prevalence of wireless networks and devices and heightened EMF exposure.

If you are concerned about adverse health effects or have EMS symptoms and want to limit your EMF exposure, purchasing an EMF meter is your first step.

Shopping for the best EMF meter to suit your needs can be overwhelming, with many different choices in models and specifications. Understanding these meters and what they do will make your selection process easier. 

Understanding EMF Meters

A standard EMF meter is a scientific device for measuring or detecting radio frequencies and electric/magnetic fields for research or personal home use.

Most EMF meters read alternating current (AC) electricity, the standard current in homes and devices that is more common than direct current (DC).

Different EMF meters will also measure certain fields and hertz frequencies (the unit of measurement for wavelengths). The hertz frequency range is a significant factor when considering which EMF meter to buy.  

For personal use, an EMF meter can help you identify the type, severity, and source of your EMF exposure so you can choose the appropriate EMF protection.

For example, you may discover that you do not need 5G protection, you are dealing with severe exposure to dirty electricity, or your WiFi network and cell phone are affecting your sleep

When you understand what a model measures, how it displays the data, and where it can be used, you’ll have greater clarity when selecting your EMF meter(s).


Evaluating an EMF Meter

An EMF meter is available in two types: a single-axis or tri-axis. A single-axis EMF meter is usually cheaper but takes longer to make measurements. A tri-axis is more expensive but measures all three EMF axes at once.

Other factors include detection and data displays. Regarding these, there is no right or wrong, so you can choose what works best for you.


An EMF meter can detect radio frequencies, magnetic fields, electric fields, or a combination of the three. (Some measure all three simultaneously.)

A radiofrequency EMF meter reads the EMF generated by wireless networks and devices. There are now a number of EMF meters that can also detect current 5G frequencies.

Electric and magnetic EMF meters measure EMF from electrical wiring, lines, and devices, as well as solar panels and EMF-emitting lights.

There are also specialty EMF meters for measuring dirty electricity, the electrical pollution caused by interruptions to electrical flow.

Frequency Range

The range of the EMF meter is important because different sources use different frequencies. 

Radio frequencies are between 3 kHz and 300 GHz (according to the WHO), although different devices are restricted to certain frequencies.

Home WiFi networks use 2.4 GHz or 5 GHz (not to be confused with 5G). LTE cell phones use the 800 MHz, 1800 MHz, and 2600 MHz radio frequencies.

5G networks use higher frequencies compared to other networks. A low-level EMF meter will not detect 5G radiation.

The average power grid frequency in North America is 60 Hz, while most other countries use 50 Hz. 

An EMF meter that reads below 20 Hz isn’t generally necessary for home use.

Accuracy and Sensitivity

The accuracy and sensitivity levels can make the EMF meter difference for people with EMS. Some EMF meters focus more on sensitivity and/or accuracy than others, which may prioritize being more versatile and providing powerful readouts.

People with EMS will benefit from at least one EMF meter with a low margin of error and high sensitivity. Weighted measurements, which account for the EMF levels in human bodies, can also show a clearer picture of EMF exposure.

Data Display

Some EMF meter data displays use generalized ranges with lights and color codes so the EMF type and exposure severity are instantly recognizable. Others use exact numbers and multiple readings for greater accuracy.

A few EMF meters also have audible cues for determining different frequencies or sources. These may use different tones, volumes, or sounds.


The cost of an EMF meter is variable, ranging from $20 for low-end basic models to around $200-$500 for the more accurate scientific models.

A reliable and accurate EMF meter with valid results is worth the investment. Reputable EMF meter companies will offer a warranty, which will help protect your investment.


Finding Reputable EMF Meters

You can buy a super cheap EMF meter from Walmart or Amazon, but putting your health in the hands of those models is risky. They generally detect fewer EMF sources with lower accuracy.

EMF Protection currently offers six reputable and highly-reviewed models that can fulfill different specifications and needs.

Using EMF Meters for EMF Protection

The FM5 Path 5G Monitor

You can use the appropriate EMF meter to determine which EMF protection you’ll need, whether it’s for your sleeping area or along your commuter route.

The CDC’s guide on radiation exposure recommends the ALARA strategy, which means “as low as reasonably achievable.” This three-point strategy focuses on minimizing the time and distance between you and the radiation source, or using protective shielding.

Minimizing time and distance isn’t always practical for sources like cell phones and power lines, so EMF shielding is the best way to limit your EMF exposure. EMF shielding comes in everything from paint to beanies to tents.

EMF Bed Canopy / Faraday Cage Bed

EMF bed canopies are very effective at blocking EMF. They surround your entire sleeping area, leaving minimal room for EMF exposure. To purchase an EMF bed canopy, look for size, shape, and fabric.

EMF bed canopy size corresponds with mattress size, from twin to California King. The shape comes in a dome, box, or four-poster frame.

Different fabrics also block different EMF frequency ranges, with most fabrics offering WiFi shielding. 

BlocSilver™ EMF Shielding Tent
BlocSilver® EMF Shielding Tent

EMF Shielding Tent

Like an EMF bed canopy, an EMF shielding tent offers area protection with even tighter coverings than a canopy. 

An EMF shielding tent is portable and easy to assemble. It offers EMF protection when you are on the go at motels, Airbnbs, using an RV, or staying with friends and family.

If you are traveling around, you can use a portable EMF meter, like the EMFields PF5 or FM5, to let you know when to pop out your tent.

EMF Shielding Clothing

When you’re awake and moving around outside your home, EMF shielding clothing offers the best protection. For people worried about their head exposure, WiFi shielding hoodies and beanies are available.

Other EMF shielding clothing includes shirts, leggings, and shorts. There are even WiFi shielding bands to protect pregnant abdomens.

BlocWave® Freedom EMF Protection Hoodies: Unisex

EMF Shielding Paint

EMF shielding paint is highly effective at WiFi shielding and 5G shielding. You can use multiple layers of paint for higher protection.

Although it is usually black, you can paint a layer of regular paint over it with a topcoat color of your choice – this will not interfere with the WiFi shielding. 

EMF shielding paint also blocks electric fields, so EMF meters that can measure all three fields, like the Trifield T2, will give you the best accuracy on where to paint and how many layers of paint you need.

EMF Shielding Fabrics

EMF shielding fabrics are the most versatile form of protection and can be for a variety of uses. They come in many materials including cotton, mesh, and polyester.

You can block EMF from windows using curtains and screens made from EMF shield fabrics. You can also fashion device coverings, room dividers, and wraps.

Using a high-frequency EMF meter, like the FM5 Path 5G Monitor, will tell you which EMF shielding fabric you need and where it will work best.

5G EMF Protection

Because 5G network installation is newer, not every EMF protection product has the capability for 5G shielding. Certain brands offer specific 5G shielding products.

BlocWave® offers a 5G-shielding sleeping bag and BlocSilver® has bed canopies and a faraday tent. YSHIELD® has a selection of 5G shielding paints.

You can also buy 5G shielding fabric to make your own custom protection shields for areas and devices. If you or someone you know has sewing skills, you can make 5G shielding clothes like scarves. 

An EMF meter like the FM5 Path 5G Monitor will let you know if you need additional 5G protection.
