Low EMF Infrared Saunas – Brand Levels Listed and Rated

Want to Detox Without High EMF?

You are looking for a low EMF infrared sauna.  Many brands claim they were the first to offer a low EMF sauna.  Which really is the lowest and how small of a reading is needed?  

We want this page (and website) to answer those questions clearly for you and save you hours of time.  This entire website is based on 4 years on continual research and numerous discussions with company owners.

The industry’s Electromagnetic Fields (EMF), measured in milligauss (mG), range from <1.0mG up to an extremely dangerous 170.0mG on some cheap brands.  Let’s look at how you can choose a safe one.

What Are Safe EMF Levels?

A safe level of ElectroMagnetic Fields is considered to be anything below 3.0mG (lower is better).  Levels between 3.0mG and 5.0mG are marginal and equivalent to cell phone usage.  The safe emf levels you should look for in an infrared sauna are discussed at the end of this page.

Which Low EMF Sauna is the Lowest?

The short answer to this question is Clearlight.  They pioneered low emf far infrared saunas and shared their method via video a decade ago so others could duplicate the process.  Dr. Raleigh Duncan founded the company 22 years ago to offer clean safe infrared in an industry which at that time had mostly dangerous and vastly inferior products.

Thankfully today many other have eliminated most of the toxic materials and have lowered their Electromagnetic Fields as well. You want to heal with infrared therapy in a safe manner.

Very Important Note: It is critical to know WHERE the readings were actually taken and who did the testing.  Levels drop quickly as you move away from the heaters.  An acceptable mG number in the middle of the unit could still have massive levels near the heating element itself.  The readings should be taken within 2 inches of the heating element surface.

Most companies that claim to have low EMF saunas have no evidence supporting this.  We applaud Clearlight, Sunlighten and HealthMate for being three of the companies that post third party test results on their websites.

Below are the posted third party test results for Clearlight.   It’s readings were taken within 2″ of the heater surface.  Distance from the heaters is very important.

Readings taken within 2″ of heating panel

One popular brand informed us that they has lowered their levels to 10mG (which is still high).  However, after further research, we discovered those numbers were taken in the center of the unit.  The company later confirmed to us that readings next to the heaters were 30mG.

What is Low EMF Sauna?

A Low EMF Sauna is an infrared sauna with a reading lower than 3.0mG.  Many brands will claim a low emf sauna is lower than 5.0mG.  The best readings will be <1.0mG and the very best will boast 0.05mG and lower. Once 3.0mG is reached, other considerations become important, as we explain below.

What is a High EMF Reading?

A high emf reading is 10.0mG up to 100mG and above.  We have found one infrared sauna with a reading above 170mG which is extremely high.  While it is not absolutely critical to drop much below 3.0mG, 30mG and above is very dangerous.

So which popular industry names make the cut?

Low EMF Sauna Brands with Safe mG Levels?

Heavenly Heat Dry/Wet Combination

Heavenly Heat Combination Sauna 2024

All models of Clearlight and Heavenly Heat pass this test.  However, Heavenly Heat’s newest heaters as of March 2024 reduce the EMFs even further and also dramatically address the ELF dangers as well.

Saunacore’s higher end models are safe but the lower end units may not be.  Sunlighten has also substantially reduced the Electric Magnetic Fields readings over the past decade.  Vital Health has reduced their levels to below 3.0. Sunlighten has reduced their levels to below 3.0 on their long standing line of Signature Series but their newer mPulse has reported levels of over 10.0 milligauss.  Our readings were 3.5-5.0 mG on the mPulse.

These are all listed in the table below.

Heaters are the Most Important

You want to purchase a well built product by a great company with a good warranty.  But once you own the unit, what you then need is heating elements that will offer deep penetrating infrared.  There really is no company that has a completely no emf infrared sauna.  But as long as the levels are at the safe readings, the difference between 2.0mG and 0.05mG is not as critical.

HealthMate Sauna Tecoloy Heaters

With that said, the brand we have at our home is Clearlight.  This one was chosen 4 years ago after a few months of research and discussions with several doctors and owners of several companies.  Once we knew all the differences between brands, Clearlight was a very easy decision.

Is Heater Emissivity more Important Than Ultra Low EMF?

Vital Health Saunas 2 person Elite

Vital Health’s newer Gen III panels have High emmisivity

As long as the ElectroMagnetic Fields readings are in the safe level, Emmisivity and Efficiency are more important.  So what is emissivity?

This is basically asking what amounts of infrared are being emitted by he heating element and how much of it penetrates your body.  The entire purpose of infrared is for it to penetrate 2″ into the body.  This is what heals tissues and cause toxins to be released and eliminated from your body.

A low emf far infrared sauna with poor emissivity provides very little benefit for you.  We are surrounded by magnetic fields all day long in our modern electric world from cell phones to computers.  The key is to reduce when we can and to avoid long tern exposure at higher levels.  So trying for a fully no emf sauna with a stated level of zero is not necessary.  And no one truly has zero Electromagnetic Fields.

Can We Have Both Low EMF and High Emissivty?

Fortunately some companies have product lines offering us both low emf saunas and highly efficient heaters.


Clearlight’s True Wave II High Efficiency Panels

Again, Clearlight seems to be the front runner with 22 years of history.  It’s unique blend of carbon panels with ceramic fibers has the most penetrating infrared of any brand.  Heavenly Heat, which uses 304 surgical stainless steel Ceramic, has levels of below 3.0mG and heater efficiency of 96%.  Saunacore also uses 304 surgical stainless steel Ceramic with the same great ratings, although we do not recommend that brand due to other concerns.

Many companies have poor heating efficiency ratings of 50%.  That is due to using cheap rods that were originally designed for drying paint or other industrial uses.

Low Emf Sauna – Why Safe Levels are Important

Choosing a low emf sauna is a critical factor when making your purchase decision. Carbon has many advantages over Ceramic when used for healing therapy.  However, carbon inherently emits higher Electromagnetic Fields. While there is still no truly no emf sauna, we are all fortunate to have companies which have reduced the levels emitted from their carbon panels.

While both the United States Environmental Protection Agency (EPA) and Sweden Agencies consider levels below 3.0 milligauss to be safe, many brands currently on the market have levels of 10-30 milligauss and a few are even emit over 100 milligauss.  The levels are important and extended exposure at these levels can be dangerous to your health and should be avoided.

What is EMF?

EMF are Electromagnetic Fields.  Electromagnetic Fields are electric energy waves at frequencies below 300 cycles per second. We encounter electromagnetic fields on a daily basis emitted from hundreds of electrical devices including power lines, cell phones, television and computer screens, fluorescent lights and even house wiring.

So what does emf mean for us? With modern electricity, we are daily exposed to emf meaning we cannot avoid it entirely. The important thing is to put distance between yourself and the electric device when possible and avoid excess and unneeded exposure.  Even using a cell phone exposes us to the fields.  In the case of an infrared sauna emf levels can be researched and we have the choice to avoid those products with emfs beyond the safe level.

The California Public Utilities Commission (CPUC) has created  a program called the California Electric and Magnetic Fields Program to study and educate regarding these potential health risks of continued exposure.

You want all of the health benefits infrared saunas offer including improved skin, weight loss and pain reduction.  These healthy benefits can all be obtained by safely increasing your body temperature using natural infrared heat therapy.


The Earths magnetic field will always create fields of energy and some studies have been inconclusive on the level of this danger.  However, it is easy to decide between two extremes.

When choosing between a full spectrum low emf infrared sauna and one that has stated levels of 30-175 mG, it makes sense to strongly consider the one you know will not pose any risk.   This is especially true when these same brands also have the best penetrating infrared, offering the highest levels of health and detoxification benefits.  It was those considerations, combined with the recommendations by Whitaker Wellness Clinic, Hippocrates Institute and others that promoted me to purchase a Clearlight for my personal use.

The smaller the cabin, such as in a one person infrared sauna, the more the emf will increase in a cheap unit with cheap carbon panels.

We recommend you read some of our individual review page and choose a brand that is safe and effective without risk.

While a cheap price is certainly a cheap product with little benefit, a very high price does not always mean your best choice.
