7 Best Low EMF Infrared Saunas [2025] With Buyer’s Guide

Infrared saunas are more popular than they have ever been, offering benefits like muscle recovery, detox support, stress relief, and overall wellness. But as more people bring them into their homes, I'm getting asked more and more often: What about EMF exposure?

The reality is, a lot of infrared saunas emit a really high level of electromagnetic fields (EMFs), especially cheaper, older models, as they tend to lack proper shielding.

Since you sit in a closed box, next to electronics and heaters that are emitting EMF radiation, for extended periods, the exposure can add up really quickly.

That's why I created this guide.

I've spent years and years researching EMF safety, testing hundreds of products firsthand, and helping people like you make good decisions when it comes to EMF protection.

In this article, I'll help you navigate:

• What makes a sauna “low EMF” (and what to look out for)
• The different types of infrared heating (far, near, full spectrum)
• The best low EMF sauna options for various budgets and spaces
• Common red flags and testing methods you can use at home

Whether you're just starting your wellness journey or are already EMF-conscious, I wrote this guide specifically to help you choose a safer, smarter, better infrared sauna.

Let's get started.

Why EMF Matters in Infrared Saunas

Most people who purchase an infrared sauna are doing so because they want to improve their health, not realizing that some models may expose them to high levels of EMF radiation during every session.

The problem?

Your typical at-home infrared sauna is going to have you sitting in a small wooden box, surrounded by heating elements, wiring, power supplies, and electronic controls, often very close to your body, for 20-40 minutes at a time.

If you buy an infrared sauna that wasn't intentionally designed to minimize EMFs, your body could be absorbing much higher levels of radiation than it needs to, which can affect your body's ability to heal and relax.

What Exactly Are EMFs?

EMFs (electromagnetic fields) are invisible waves of energy that are emitted by anything that uses electricity, and fall into two main categories:

• ELF (Extremely Low Frequency) – This is from things like wiring, heating elements, transformers, etc.
• RF (Radio Frequency) – This is from things like WiFi, Bluetooth, and other wireless devices. This will be less common in an infrared sauna unless it has some Bluetooth speakers or controls.

Although the science and understanding of EMF radiation exposure are still developing, hundreds of peer-reviewed studies have linked regular exposure to biological effects, including oxidative stress, DNA damage, sleep disruption, and much more.

For these reasons and others, more and more people are beginning to listen to doctors and environmental health experts who advise reducing their EMF radiation exposure as much as possible.

Saunas Can Be EMF Hotspots

Many saunas marketed as “low EMF” still emit 8–20 mG near heater panels, and often fail to disclose that their full-spectrum heaters are the problem.

For context, the EPA and Swedish guidelines suggest keeping exposure under 3 mG.

Why It Matters

If a sauna isn't independently tested and well-shielded:

• You're sitting in potentially 10-50 mG fields, far above safe thresholds.
• Marketing terms like “zero EMF,” “no EMF,” or “low EMF” often don't account for the ELF at seating height.

Luckily, there are some “low EMF” and “no EMF” saunas that are actually what they claim to be, and in this guide, I'll help you find the right one for you.

How Infrared Saunas Work

If you want to understand what makes for a “low EMF” sauna, it really helps to first gain a basic understanding of how infrared saunas really work and how they differ from traditional saunas.

Instead of heating the air around you, like a traditional sauna, infrared saunas use infrared light waves to directly heat your body.

This allows them to operate at lower temperatures while still providing many of the same (and often some deeper) benefits, like increased circulation, detoxification, and muscle recovery.

There are three main types of infrared saunas, categorized by the wavelengths of infrared light they emit:

1. Far Infrared (FIR)

Far infrared is the most common type you'll find in home saunas. It penetrates deep into the body and does a really good job of detoxification, pain relief, and relaxing you.

Far infrared heaters typically emit the least amount of EMF radiation when well designed, especially those that use carbon panel technology (we'll talk about this more later).

2. Near Infrared (NIR)

Near infrared uses a shorter wavelength that's more surface-level in how it affects you. It's often used for skin rejuvenation, mitochondrial stimulation, and sometimes even in the healing of significant wounds.

NIR typically comes from LEDs or incandescent light bulbs, and although it has its uses and benefits, it typically emits higher amounts of EMF radiation in my experience.

3. Full Spectrum

Full-spectrum saunas combine near, mid, and far infrared light for a more holistic experience. These saunas tend to be the most advanced, but also the most complex when it comes to EMF exposure.

Since they include multiple types of heaters and controls, proper design and correct shielding are extremely important.

Why Heating Element Design Matters

The type and placement of the heating element in whatever sauna you ultimately choose to purchase can have a huge impact on the EMF levels. For example:

• Carbon heaters tend to produce the lowest level of EMFs, lower than ceramic rods.
• Panel layout affects how close you are to higher EMF areas of the sauna.
• Wiring design and shielding can significantly reduce how much EMF radiation you are exposed to when done correctly.

That's why even among saunas that you'll see marked as “low EMF,” the actual design and independent testing matter much more than their marketing claims.

What Makes a Sauna Truly Low EMF (What To Look For)

Since more and more people understand the risks of excessive exposure to EMF radiation, more and more sauna companies are advertising their products as “low EMF” or even “zero EMF.”

Unfortunately, most of these claims are either poorly defined, unverified, or based on very misleading testing methods or results.

If finding an actual low-EMF sauna is important to you, here is what you should look for.

1. Independent EMF Testing

This is really the gold standard, and what you should look for first if a sauna brand is advertising that their sauna emits low or zero EMF radiation.

If they do, they should be able to provide (or have published on their website:

• Testing reports from third-party labs (not in-house testing)
• Measurements for both ELF (magnetic/electric fields) and RF (radio frequency) radiation levels.
• Clear explanation or diagram of where the readings were taken (at seating level, near the backrest, on the floor, etc.)

2. Readings Below 3 Milligauss

Unlike regulated products like cell phones, which have to meet certain standards for radiation emissions, saunas don't really have universally enforced limits.

However, the general consensus among experts seems to be that you should try to keep your chronic EMF exposure under 3 mG. This is especially important when the radiation source is very close to your body.

Try to find sauna brands that provide verified readings below 3mG at every key point of contact in the sauna (not just a single location away from where you sit).

3. Well-designed heater and wiring layout

A low-EMF sauna isn't just about shielding; it's also about smart design and engineering.

Try to find a sauna that has:

• Carbon panel heaters (these typically emit the least amount of EMFs.
• Wiring that runs behind wall panels, away from where you sit.
• Grounding and EMF shielding to help limit electric fields.

4. Shielding of the Power supplies & controls

A truly low-EMF sauna will isolate or shield components such as the power supply box, the control panels, LED lighting, Bluetooth components, etc.

Best Low EMF Infrared Saunas (2025)

There are lots of infrared saunas out there that claim to be “low EMF,” but many of them really don't live up to the hype.

I've spent dozens of hours researching real EMF test results, looking at sauna designs, materials, certifications, etc., to put together this list.

Below are my top recommendations for infrared saunas across different categories (1-person, 2-3 person, budget-friendly, portable, and luxury).

1. Dynamic Barcelona 1-2 Person Far Infared Sauna

Check the current price on Amazon.

If you want a high-quality, reliable, and truly low-EMF sauna for solo (or occasional two-person) use, the Barcelona model by Dynamic saunas has to be one of the best options on the market right now.

I love a lot of things about this sauna, but here is what I think is most important for you to know.

Key Features

Low EMF Carbon Heating Panels – The Barcelona is equipped with 6 of Dynamic Saunas' trademarked “PureTech” carbon infrared heaters, which offer soft, gentle, even heat, while still emitting very low levels of EMFs.

Utilizes Canadian Hemlock Wood – Known to be durable, attractive, and resistant to warping from heat exposure, Canadian Hemlock is the perfect wood for a low-EMF sauna.

No Special Wiring Needed – Plugs into a standard 120V outlet, making it easy to set up in your home without the need for an electrician.

Heats Up Quickly – It typically only takes around 20-30 minutes to reach full heat.

Small Footprint – I also like that this sauna has a fairly small footprint, of just 39 x 36 inches, making it fairly easy to find a spot for in your home.

Things to consider

One thing to consider is that although it says it's technically a 2-person sauna, most people found that it is really only comforatable for a single user.

If you plan to use this sauna regularly with a second person, you might want to think about getting a larger model.

2. Dynamic Andora 2-Person Far Infrared Sauna

Check the current price on Amazon.

If you're looking for a low-EMF sauna that gives you a bit more space than the Barcelona I talked about above, than the Dynamic Andora is probably the right option for you.

It's still small enough in size that it works for most home setups, but the larger interior is really noticeable if you spend a good amount of time inside with two people.

There are a lot of things I like about this Sauna (and all the Dynamic saunas), but here are the important ones I think you should know.

Key Features

Low EMF Carbon Heating Panels – The Andora uses the same “PureTech” carbon infrared heating technology found in the Barcelona. These panels produce a really nice, soft, even heat that has been tested to emit less than 3 milligauss (mG) at seating level.

Enough Space For Two – With exterior dimensions of about 48″ x 42″, the Andora offers a good amount of interior space, plenty enough for two, and enough for a very cozy single-user experience.

Built From Canadian Hemlock – Just like the Barcelona, the Andora uses reforested Canadian Hemlock for most of its construction. This wood is beautiful, non-toxic, and is known for it's durability and low VOC off-gassing.

Tool-Free Assembly – The sauna panels use Dynamic's clasp-together system, which made the installation really quick and straightforward. Two people can put the whole thing together in about an hour or less.

Things To Consider

Although this model is a nice upgrade from a single-person sauna, it's still a little on the cozy side for two larger adults.

Also, keep in mind that it's a far-infrared sauna, which is perfect for gentle, therapeutic heat. It does not offer the very high temperatures that a traditional sauna would. So, if an intense sweat experience is what you're looking for, a hybrid or full-spectrum model may be a better fit.

3. Real Relax Infrared Sauna (2‑Person FAR Infrared)

Check the current price on Amazon.

Real Relax is another brand that is doing a great job or producing near-zero EMF FAR infrared home saunas at an affordable price.

It has a really clean, simple design, made out of similar quality materials as the Dynamic line, and receives great reviews from the people. that use it.

Here are the things I like most about the 2 person FAR infrared sauna from Real Relax.

Key Features

Low EMF Certification (<2mG) – One of the standout claims of the Real Relax sauna is its near-zero EMF rating. While not independently third-party tested (as far as I can tell), the listed EMF levels are under 2mG, which is promising for a well-reviewed sauna on Amazon.

Canadian Hemlock Construction – A reliable wood choice for infrared saunas, Canadian Hemlock is known for its durability and resistance to cracking or warping over time.

Fast Warmup & 5 Carbon Heating Panels – Heats up in about 15–25 minutes with a max temp of 149°F. The five carbon panels offer consistent heat with a gentle infrared feel.

Compact but Roomy – Measures about 47″ x 35″, giving it a small enough footprint to fit in most home setups while still offering enough interior space for two people to sit comfortably.

Things to Consider

This model does require a dedicated 20-amp, 120V outlet, so you’ll likely need to hire an electrician unless you already have one installed.

Also, while the build quality is solid for the price, it doesn’t carry the same level of independent EMF testing or long-term warranty coverage as some higher-end brands.

4. Outexer 1 Person Far Infrared Sauna (Model T-50C) (Best Budget Pick)

Check the current price on Amazon

If you want a very reliable, low-EMF infrared sauna, and don't want to spend a fortune, then the T-50C from Outexer would be my recommendation.

It's a great option for solo use, and despite being significantly lower priced than many other home models, it really doesn't feel cheap at all.

I’ve reviewed a lot of entry-level infrared saunas over the years, and I find that they often cut corners on some important things. The Outexer holds up surprisingly well in all the most important areas.

Key Features

Low EMF Carbon Heating Panels – The sauna is equipped with 5 carbon fiber heaters that emit far infrared heat while producing very low amounts of EMF radiation.

Compact and Efficient Design – With dimensions of just 35.2″ x 27.6″, this sauna is ideal for small spaces or apartments. Although it is pretty small, most users find it comfortable for single-person use.

Quick Heat-Up Time – Heats up to its maximum temperature (around 140°F) in about 10–15 minutes, making it easy to fit into a daily routine.

Canadian Hemlock Wood – Like many higher-end models, the Outexer uses real Canadian Hemlock, known for its durability, resistance to heat, and pleasant smell.

Things to Consider

I couldn't find information about any independent EMF lab test, which some higher-end models offer. It also uses a standard 110V 800W power supply, so it won’t get quite as hot or fast as larger units, but for most people, it still provides a solid sweat and detox experience.

5. SpringSpa Near Zero EMF 1 Person Infrared Sauna

Check the current price on Amazon.

I think that the SpringSpa single-person Infrared Sauna is a good middle ground between some of the other low EMF saunas I've talked about so far in this article.

It was designed specifically to have ultra-low EMF emissions, but still has some of the nicer features that many people are looking for in a quality sauna.

There is a lot to like about this sauna, but here are the features I think are most important to know about.

Key Features

Near Zero EMF Carbon Heating Panels – This sauna uses 5 carbon infrared panels that emit very low EMFs, often testing at under 2 mG.

Standard Plug, No Special Wiring Needed – Runs on a standard 15-amp 120V outlet, so you won’t need to call an electrician. Just plug it in and you’re good to go.

Compact But Still Comfortable – With a footprint of 35.4″ x 35.4″, it fits well in small rooms or apartments, yet users consistently report that it feels roomy enough for comfortable solo use.

Canadian Hemlock Construction – Just like pretty much all high-quality infrared saunas, the SpringSpa uses Canadian Hemlock.

Things to Consider

There’s no floor heater in this unit, so it may not heat as evenly near your feet, though most users still report a full-body sweat.

The built-in thermometer can also be a little off (some say 10–15°F higher than external readings), but this doesn’t affect performance.

Instructions could be clearer, but the setup is still straightforward.

6. LTCCDSS Outdoor Mahogany Ultra-Low EMF Sauna – 1 Person

Check the current price on Amazon.

If you are looking for a great outdoor infrared sauna that still has ultra-low EMF levels, this is the one I would probably recommend.

It's one of the few saunas that was purpose-built to have very low levels of EMF radiation, without compromisng on comfort, durability, or affordability.

Key Features

Ultra-Low EMF Carbon Heating Panels – The sauna includes 9 carbon crystal heating panels, shielded to keep EMF levels between 0.5–1.5 mG. That’s well below most indoor units, making it a great option for EMF-sensitive users.

Built To Last Outdoors – Made from solid West African mahogany sourced from Nigeria and Ghana, the wood is naturally water-resistant, splinter-proof, and highly resistant to warping; even in temperatures from -10°F to 149°F.

Spacious Design – Although technically a 1-person sauna, the interior dimensions (30” x 30” x 70.1”) provide a comfortable experience for users up to 6’5” and 300 lbs.

Easy Assembly & Strong Warranty – Setup takes about an hour with two people, and the brand backs it with a 2-year warranty.

Things to Consider

While this unit offers fantastic value for an outdoor sauna, it comes at a higher price point and may be overkill if you’re looking for something small and portable.

Also, although marketed as “plug and play,” be sure to check your outlet’s amperage requirements, outdoor placement may still require planning for power access.

7. Dynamic Bergamo 4-Person Low EMF Far Infrared Sauna

Check the current price on Amazon.

I had to include a larger sauna on here as well, becaus sometimes you want to be able to bring the whole family in, or enjoy it with friends.

The Bergamo from Dynamic Saunas is the best 4 person low-EMF infrared sauna in my opinion.

It's harder to find large infrared saunas with low-EMF because they often have a lot more electronics and surface area to shield.

Here are the things I like best about this sauna.

Key Features

8 Low-EMF Carbon Heating Panels – Distributes infrared heat evenly across the sauna while still producing fairly small amounts of EMF radiation. Heating coverage is efficient, and people that have used it report a consistent sweat session even in larger groups.

Canadian Hemlock Construction – Durable, non-toxic, and resistant to splitting or warping over time. It looks great and holds up well with regular use.

Things to Consider

Despite being listed as a 4-person sauna, most users agree it’s best suited for 2–3 people unless you're comfortable sitting a little close.

Also, it requires a 20-amp outlet, so make sure your setup at home can accommodate it before purchasing. Assembly is straightforward but heavy, ideally, have a second person help with setup.

How To Test EMF Levels In Your Sauna at Home

Even if your sauna claims to be “low EMF,” the only way you're going to know for sure is to test it for yourself. It saddens me to say it, but there are infrared saunas out there marketed as “low-EMF” that do not emit lower levels whatsoever.

Fortunately, measuring the EMF radiation from your infrared sauna (or anything else in your home) is easier and cheaper than many people realize.

Here is a simple guide on how to do it at home:

1. Choose the Right EMF Meter

To get accurate results, you'll want a quality EMF meter that measures all three kinds of EMF radiation: magnetic field, electric field, and radio frequency (you'll need this if your sauna has Bluetooth or any other wireless connectivity).

These are the two I recommend most:

TriField TF2 – This is the meter I recommend most often. It is really simple to use, very accurate, and reasonably priced.

GQ EMF-390 – This is a great option if you want to be able to dig deeper into the data when you're measuring EMF radiation.

2. Let The Sauna Warm Up

It's important to let your home infrared sauna warm up for 15-20 minutes, just like would happen in a normal session.

This will help ensure that all the heating elements, electronics, lights, etc., are drawing full power, so that we can measure the peak EMFs.

3. Taking Readings at Key Spots

Take your EMF meter, and take readings in the areas where your body will be during a typical sauna session:

• Near your head
• Backrest height
• Seat surface
• Floor around your feet

Hold your EMF meter about 1-3 inches from each surface, or about where your body would naturally be.

You want to see magnetic field readings under 3 mG. RF levels (if there are any) should be extremely low or non-existent if your sauna doesn't use wireless components.

Here are a couple of other things you'll want to look out for:

• EMF Spikes near heaters or control boxes could mean poor shielding or cheap wiring.
• Consistently high readings, even away from the heaters, may mean there is a problem with the wiring layout.

Tips to Further Reduce EMF Exposure in Your Sauna

Once you have an infrared sauna in your home, low-EMF or not, you'll probably want to find ways to reduce your exposure to EMF radiation when you're using it.

Here are a few simple tips that can help minimize your exposure even in a low-EMF sauna setup:

1. Unplug Nearby Devices

Make sure there are no other electronic devices plugged in near your sauna, especially routers, TVs, smart plugs, or Bluetooth speakers. We want the space we spend time to have as little EMF radiation as possible.

2. Keep Phones & Smartwatches Out

I get it, sitting in a sauna, especially alone, can feel pretty boring, and it can be tempting to bring your phone or iPad in. However, even in airplane mode, it's still going to emit a fair amount of radiation.

So, try to leave it outside, but if you do need to bring it inside, at least turn off the Bluetooth and WiFi if possible.

3. Sit in the Center When Possible

The sources of most EMF radiation in a sauna (like heaters or wiring) are located near the walls. So, sitting close to the center of your sauna will help give a little more distance from those sources and reduce your overall exposure.

4. Limit Wireless Features

Some newer saunas come with Bluetooth speakers, Wi-Fi, or LED displays. Although these features are really convenient, they often increase RF radiation. If you don’t use them, I would suggest turning them off.

Frequently Asked Questions About Low EMF Infrared Saunas

Do Infrared Saunas Give Off EMF Radiation?

Yes, all infrared saunas are going to emit some level of EMF radiation because they use electricity to power the heating elements, lights, etc. However, how much radiation they expose you to can vary widely between types and models.

Low-EMF saunas are specifically designed to reduce your exposure by using better wiring, better shielding, and a more thoughtful layout of components.

What is considered a safe EMF level for a sauna?

Most experts recommend staying below 3 milligauss (mG) for magnetic field exposure during long sessions.

That’s in line with guidelines from the EPA and other environmental health organizations.

The best low-EMF saunas test well below this, often in the 0.5–2.0 mG range at seating level.

How do I know if a sauna is truly low EMF?

Look for independent third-party testing and published EMF readings.. Marketing terms like “low EMF” or “zero EMF” are often vague; always check for real data.

Are near-infrared saunas higher in EMF than far-infrared?

Generally, yes. Near infrared (NIR) saunas often use incandescent bulbs or LEDs, which can emit higher electric and magnetic fields, especially if they aren’t shielded. Far infrared (FIR) saunas using carbon panel heaters tend to have the lowest EMF levels.

Final Thoughts: Choosing the Right Low EMF Infrared Sauna

If you made it to the end of this article, I commend you, and it's that finding a low EMF infrared sauna is really important to you.

Whether you choose to go with one of the low EMF infrared saunas I recommended above, or something else entirely, it's good that you're considering how EMF radiation affects you and your family.
