  • Is the infrared full spectrum?

    Yes, the infrared is full spectrum on all Finnmark sauna models.

    Does the sauna emit low EMF?

    Absolutely, with testing results backed by NTS Lab based in Arizona. To summarize, the highest reading of EMF is 1.17mG from the Spectrum Plus heaters and 0.4mG from the Spectrum (Carbon) heaters. Please refer to the EMF Facts video discussed by the founder of the company for more details.

    Are there any glues in the sauna?

    All saunas are made with some amount of glue. It's impossible (regardless of what a competitor may tell you) to construct a sauna without glue. The difference between brands is where is the glue used and the type of glue used. Finnmark Designs constructs its infrared saunas with very little glue within the sauna's cabin. This glue is located behind the cedar tongue and groove slats to hold them in place. The glue used is non-toxic (like most glues). However, our glue goes a step further and is non-toxic up to 250 degrees.

    Are there any plastics in the sauna?

    There are some plastics in the unit (specifically in the accessory outlet, screw covers and controller), but plastic material doesn’t off gas until the ambient temperature reaches 212 degrees, which is quite a bit higher than our saunas’ top temperatures.

    What did an environmental testing facility have to say about Finnmark Saunas?

    Finnmark Designs spoke with an environmental biologist in regards to testing our sauna for VOC's and any off-gassing material. After examining the interior of our saunas, the biologist did not recommend a full test as the material used was comprised of Western Canadian Cedar and metal components.
