quad-field RADIATION protection

exclusive to finnmark

Our Spectrum infrared heaters are not only extremely effective, but they are extremely low in radiation. Finnmark has gone to great lengths to protect our customers and are proud to be the only manufacturer that has taken the steps to protect against all 4 types of radiation. Electromagnetic Fields (EMF) are energy waves with frequencies below 300 hertz or cycles per second.

Be sure to ask when shopping for an infrared sauna if their infrared saunas are low radiation.

EMF testing tool

A lot of videos float around the internet using substandard radiation devices. At Finnmark, we only test our heaters and saunas with a state of the art Gigahertz Solutions NFA-1000 for the best possible results. We also employ a radiation testing lab to conduct studies on our heaters.

Using this ultra-sensitive testing equipment, all of our heaters are tested to ensure safe levels. Electromagnetic Fields are measured in milligauss (mG). Currently, there are no regulations or laws concerning EMF exposure at 60htz in the USA. However, Finnmark believes any device or heating element under 8mG is more than safe. Many sauna brands will reference studies from the EPA or other countries like Sweden that simply don’t exist.

The Spectrum carbon heater is extremely low EMF, registering under 1mG at the surface and zero at 3″. The Spectrum+ incoloy is under 3mG at the surface and close to zero at 3″.

Exclusive to Finnmark

Finnmark saunas are the only infrared saunas that use highly advanced and proprietary wire shielding in all saunas. Recommended by a certified building biologist and EMF radiation specialist.

This proprietary wire helps shield ELF and EMF to ensure that your sauna is the safest available. In addition to this proprietary shielding, we also use a proprietary method of how we route our cables within the shielding . A Finnmark exclusive.

90% EMF Reduction

100% ELF Reduction


August 2019

Based on the suggestion of our certified building biologist, we have discontinued our relationship with Vitatech Electromagnetics. This is due to their testing parameters that keep changing, making brands pay over and over for their services. Finnmark has teamed up with a NTS who is a higher authority and more respected in the electromagnetic industry. NTS tests for the following industries; areospace, defense, energy, automotive, nuclear, telecom, medical and infrared heaters.



Often not discussed by infrared sauna manufacturers are EMI and RFI radiation exposure in poorly designed saunas. For the purpose of an infrared sauna you will need to be most concerned with WIFI based controllers. Many brands love to show and tell their fancy controller that is not only extremely high in EMF’s but it has a WIFI antenna that causes major EMI and RFI frequencies.

WIFI controller

WIFI based control systems. Extremely high EMI / RF. Completely contradicts the benefits of selling the health benefits of an infrared sauna. We have tested many of these devices and the EMI / RF signals are at very dangerous levels.

Neurological, cellular and well-being health risks are not worth it. Sure, turning on your sauna from your smart phone sounds good and might be more convenient but the risks to your health are too high.

Engineering Note: Wood doesn’t block wifi signals. If this was true you would only have internet access in your home where your wifi router is located.

Using an Ipad to control your sauna?

Using a Gigahertz Solutions HFW58D our tests rendered very high magnetic fields from an iPad. This test was completed without the WIFI signal on. Peak mG from an iPad when utilizing WIFI was in the 140,000 uW per sq. meter peak which equates to roughly 140mG.

Full spectrum food heat lamps. Extremely hot (dangerous) and high EMFs even with radiation blocking screens.


The health benefits of using a quartz heater (food heat lamp) occur within 3 inches of the heat source. The positioning of these heaters within the sauna (front wall) limits your distance from harmful EMFs but you then lose all the therapeutic benefits the heater was designed for.

Incandescent lamps and Quartz heaters compare to a double-edged sword. The health and therapeutic benefits only occur within 3 inches of the heat source, however at that distance the heater can and will cause 1st and 2nd degree burns.
