The EMF Values of Infrared Saunas: Low EMF and Low ELF
A clear, evidence-based look at electromagnetic fields β and what "ultra-low EMF" actually means for your sauna.
EMF stands for electromagnetic field. It is a physical field produced by electrically charged objects, and it is generated whenever electricity flows through a wire, a device, or a power line.
EMFs are made up of both electric fields and magnetic fields. They are also all around us β produced by both natural sources (like the Earth's own magnetic field) and human-made ones (like the wiring in our walls).
EMFs are usually grouped into a few familiar categories.
Extremely Low Frequency (ELF) EMFs are typically generated by power lines, electrical wiring, and household appliances. Their frequency ranges from 3 Hz to 3,000 Hz.
Radiofrequency (RF) EMFs are generated by wireless communication devices such as cell phones, Wi-Fi routers, and microwave ovens. Their frequency ranges from 3 kHz to 300 GHz.
EMFs help shape modern life in many useful ways β from the power running through our homes to the navigation systems that guide birds, fish, and other animals across long distances.
Is EMF Harmful?
This is the question most people actually want answered.
For most non-ionizing EMF sources encountered in daily life, there is no strong evidence to support significant health risks.
Regulatory agencies such as the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) have established exposure guidelines based on the best available evidence.
That said, the science is not uniform across the spectrum. It is a useful rule of thumb: the shorter the wavelength, the more energetic β and the more potentially harmful β the radiation.
X-rays, gamma rays, and ultraviolet rays sit on the higher-energy, shorter-wavelength end. They are ionizing, and they require careful handling.
Infrared, microwave, and radio sit on the longer-wavelength, lower-energy end. They are non-ionizing, and at typical exposure levels they are generally considered safe.
Not all EMFs are created equal. The wavelength tells you almost everything you need to know.
Where Infrared Sits On The Spectrum
Infrared (IR) radiation is a type of electromagnetic radiation with longer wavelengths than visible light but shorter than microwaves.
When our skin is exposed to infrared radiation, it absorbs the energy and feels warmer. That warming effect is the entire reason infrared saunas work.
Infrared radiation is classified as non-ionizing. It does not carry enough energy to ionize atoms or molecules β which is the mechanism by which higher-energy radiation damages biological tissue.
For that reason, infrared radiation is generally considered safe at the exposure levels encountered in everyday life β including during a regular sauna session.
Key Insight
SalusHEAT has been using ultra-low EMF carbon panel heaters for our business partners since 2010.
In our SalusHEAT Saunas Direct store, the EMF readings in saunas other than the Maxwell series typically fall within the 10-20 mG range.
The new Maxwell series goes further. EMF levels are as low as 0.5 mG β meaningfully lower than the 100+ mG readings found in many other sauna brands on the market today.
The Maxwell Series: Ultra-Low EMF, By Design
The Maxwell line of infrared saunas is named after James Clerk Maxwell β the scientist whose work on electromagnetism helped shape modern physics.
It is a fitting name. The series is built around the same principle: a more thoughtful, more engineered relationship with electromagnetic fields.

Registered U.S. Patent For Low-ELF, Low-EMF Heating
The Maxwell infrared heater is not just a marketing claim. It is protected by a registered U.S. patent.
The patent covers an infrared sauna heater engineered to deliver both low electric field (ELF) and low electromagnetic field (EMF) radiation β without the use of any shielding material.
The design integrates a low-ELF, low-EMF room heating plate with a shielding wire, an insulating layer with concave and convex points, and a stranded power wire with an electric-field-absorbing shielding layer.
Why This Matters Compared To Other Low-EMF Claims
Many infrared sauna brands claim to have low EMF. Few of them address the electric field at all β and those that do usually rely on a conductive mesh or metal grill to do it.
The Maxwell technology is different. It addresses both ELF electric field and EMF radiation together, in a single engineered heating element, without any shielding material added on top.
That distinction is more than technical. It is the reason the EMF readings on a Maxwell sauna are an order of magnitude lower than many competing products.
Most low-EMF claims stop at the magnetic field. The Maxwell design goes one step further β to the electric field as well.
Is "low EMF" something to look up β or something to ask the manufacturer about directly?
The Bottom Line
EMF is not a single thing. It is a category, and the safety profile varies a great deal depending on where you sit in the spectrum.
Infrared radiation, including the kind used in infrared saunas, is generally considered safe at typical exposure levels.
For those who want extra peace of mind, the Maxwell series offers independently tested ultra-low EMF readings β as low as 0.5 mG β supported by a registered U.S. patent.
That is a different conversation than most sauna brands are having. It is also a more useful one.
The most thoughtful wellness products are the ones that respect what the science actually says.
Frequently Asked Questions
What does EMF stand for?
EMF stands for electromagnetic field β a physical field produced by electrically charged objects. It is generated whenever electricity is used or transmitted.
Is EMF dangerous to human health?
For most non-ionizing EMF sources encountered in daily life, current evidence does not support significant health risks. Regulatory agencies such as the WHO and the ICNIRP have established exposure guidelines based on this evidence.
What is the difference between ELF and RF EMFs?
ELF (Extremely Low Frequency) EMFs come from power lines, wiring, and household appliances, ranging from 3 Hz to 3,000 Hz. RF (Radiofrequency) EMFs come from wireless devices like phones, Wi-Fi routers, and microwaves, ranging from 3 kHz to 300 GHz.
Are infrared saunas safe from an EMF perspective?
Infrared radiation is non-ionizing and is generally considered safe at typical exposure levels. For users with extra concerns, ultra-low EMF saunas such as the SalusHEAT Maxwell series offer readings as low as 0.5 mG.
What makes the Maxwell series different from other low-EMF saunas?
The Maxwell heater is engineered to reduce both ELF electric field and EMF radiation together, in a single element, without relying on external shielding. The design is protected by a registered U.S. patent.
