Which Infrared Sauna Has the Lowest EMF and ELF Levels?

A good infrared sauna produces barely any EMF or ELF, about as much as sitting next to a lamp. Revel Saunas are tested to make sure they stay well within safe limits, making them one of the most trusted choices for everyday home use in Australia.

If you've been reading about infrared saunas, you've probably come across the terms EMF and ELF. They sound technical, and maybe a bit worrying, but they don't need to be. This guide explains it all in plain English so you can feel confident about your decision.

The short version: some saunas produce more of this invisible energy than others. Revel Saunas are specifically designed to produce as little as possible. Here's what that means and why it matters for your health.

What Are EMF and ELF? (No Jargon Version)

Every electrical device, your phone, your fridge, your TV, gives off a tiny amount of invisible energy when it's plugged in and running. That energy is called EMF. Your infrared sauna does the same thing because it runs on electricity too.

Picture it like this: when electricity flows through a wire, it creates a small invisible "bubble" of energy around it. That's EMF. You can't see it, feel it, or smell it, but it's there, and it radiates from anything electrical.

EMF (Electromagnetic Field): The invisible energy your sauna's heaters and wiring give off when switched on. The unit of measurement is milligauss (mG). Think of mG like a volume dial, the lower the number, the quieter the energy.

ELF (Extremely Low Frequency): A specific type of EMF that pulses 50 times per second, the same rhythm as the power in your home's wall sockets. It sounds scary but it's the same energy your power outlets produce all day, every day. "Extremely low frequency" describes the pulse speed, not the danger level.

So why do people care about it in saunas specifically? Because when you're inside a sauna, you're sitting very close to the heaters for 20–40 minutes, and often doing this every day. That's more close contact time than almost any other electrical device in your home. Health focused buyers want to make sure that exposure is kept as low as possible.

The reassuring part: a well built sauna like Revel keeps EMF so low it's barely above what you'd find just sitting in a room. No need to panic, just pick the right one.

How Much EMF Is Actually Safe?

There's no single magic number everyone agrees on, but there are two useful benchmarks to know:

• The international health guideline (used by bodies like the WHO) sets the limit for everyday public exposure at 2,000 mG. Every sauna on the market, even a bad one, sits well below this. So in terms of official safety, all saunas pass.

• The tighter standard, used by health focused researchers and building biologists, recommends below 1 mG for spaces where you spend a lot of time. This is the benchmark serious sauna buyers aim for, and it's what Revel Saunas are designed to meet.

• Think of it this way: the official limit is like a highway speed limit. The building biology standard is like what a careful, health aware driver would actually choose to do. Both are "safe", one is just more cautious.

What to look for when buying: Ask any sauna brand for their EMF reading in milligauss (mG), measured 30 cm from the panel, that's about where your body sits. Under 1 mG is the gold standard. Revel meets this across the range.

How Does a Sauna Compare to Your Phone and AirPods?

Here's something that surprises most people: your infrared sauna is probably one of the lowest-EMF devices you own.

Phones and wireless earbuds actually emit a different type of electromagnetic energy,  called radio frequency (RF) radiation, from their Bluetooth and cellular signals. It's all technically "EMF," but RF radiation from a phone pressed to your head is a very different thing to the low-frequency magnetic field from a sauna heater 30 cm away.

The takeaway: a quality Revel Sauna exposes you to less low frequency EMF than simply sitting in your own home. Your AirPods and phone are a much bigger part of your daily EMF picture, and yet they're the things most people never question.

How Do Infrared Sauna Brands Reduce EMF and ELF?

Not all heating technologies produce the same emission levels. Here's how manufacturers reduce EMF/ELF:

1. Carbon Panel Heaters

Carbon fibre panels distribute heat across a large surface area at lower temperatures than rod heaters. Because they use less electrical current to achieve therapeutic temperatures, they generally produce lower EMF. Most quality brands, including Revel,  use carbon panel technology for this reason.

2. Cancellation Wiring

Some manufacturers run wiring in a cancellation configuration, pairing wires so their electromagnetic fields cancel each other out. This can reduce EMF readings by 50–80% compared to standard wiring.

3. Low Voltage Heating Elements

Operating heating elements at lower voltages reduces the strength of the resulting EMF. Combined with cancellation wiring, this brings readings to near zero at body distance.

4. Independent Third Party Testing

The most trustworthy brands submit their saunas to independent testing labs, not just internal measurement. Look for brands that publish actual test results, not just marketing claims of "low EMF."

Why Revel Saunas Are Among the Lowest EMF Options in Australia

Revel Saunas is an Australian brand built specifically for the Australian market, and EMF safety is one of the core engineering priorities across the range.

Carbon Panel Heating Across the Range

Every Revel infrared sauna uses full-coverage carbon panel heaters. These low current panels distribute heat evenly across walls, floor, and ceiling, reducing both the electrical current required and the resulting EMF/ELF output compared to spot heat ceramic rod alternatives.

Cancellation Wiring Architecture

Revel's wiring design uses a cancellation configuration throughout the sauna cabin. Paired cable runs neutralise opposing magnetic fields, resulting in near-zero EMF readings at the standard 30 cm body distance test point in most models.

Australian Standards Compliance

All Revel Saunas meet Australian electrical safety standards (AS/NZS) and are tested for the Australian market, not just adapted from a northern hemisphere product. This matters because AU/NZ power standards (230V, 50Hz) affect both performance and emissions.

Transparency on Testing

Revel provides EMF and ELF test data on request and publishes this information for individual models. If you're comparing saunas and a brand won't show you the numbers, that's a meaningful signal.

Pro tip: Don't just settle for a "low EMF" promise. Have a Revel wellness expert walk you through a live EMF test and give you the specific mG reading for your sauna model.

How to Verify EMF Levels Before You Buy

Don't rely on marketing language alone. Here's how to verify any sauna's EMF claims:

• Request readings in milligauss (mG) at body distance (30 cm), not just "at the panel surface" where readings are naturally lower.

• Check whether the reading covers both EMF (magnetic field) and ELF (electric field), some brands only disclose one.

• Ask which models the data applies to, some brands test their flagship and extrapolate to the whole range.

• If you already own a sauna, a building biologist can measure your unit with a gaussmeter for around $150–$300.

Frequently Asked Questions

What is a safe EMF level for an infrared sauna?

Building biology guidelines, the most conservative benchmark used by health-focused researchers, recommend below 1 milligauss (mG) of EMF at body distance. Most quality carbon panel saunas, including Revel models, meet this threshold.

Is EMF from infrared saunas dangerous?

At the levels produced by consumer infrared saunas, there is no established definitive harm. However, because sauna sessions involve prolonged, close proximity exposure several times per week, many buyers choose low EMF models as a precautionary measure, particularly for daily therapeutic use.

What's the difference between EMF and ELF in saunas?

EMF refers to the magnetic field produced by the electrical current (measured in mG), while ELF (Extremely Low Frequency) refers to the electric field component of the same 50–60 Hz current (measured in V/m). A truly low emission sauna measures low on both.

Are carbon panel saunas lower EMF than ceramic saunas?

Generally, yes. Carbon panel heaters distribute current over a larger surface at lower intensity, producing lower EMF than ceramic rod heaters, which concentrate heat and current in smaller elements. Revel Saunas use carbon panel technology across the range.

Do Revel Saunas have low EMF?

Yes. Revel Saunas are designed with carbon panel heaters and cancellation wiring to minimise EMF and ELF output. Test data for specific models is available on request from the Revel team.

How do I test EMF in my infrared sauna?

You can purchase a gaussmeter (available online from $50–$200 AUD) to measure the magnetic field inside your sauna during operation. Hold the meter at body distance from the panels (approximately 30 cm). For a professional assessment, a building biologist can provide a full report.

Can I reduce EMF exposure while using my sauna?

Yes, distance is your biggest ally. Sitting in the centre of the sauna rather than leaning against panels reduces exposure. Avoid placing your phone or other devices inside the cabin. Choosing a low EMF sauna from the outset, however, is the most effective strategy.
