We chose to partner with Clearlight Infrared Sauna® since they offer the lowest EMF levels of any wooden infrared sauna on the market. The EMF levels in your Clearlight Premier™ and Clearlight Sanctuary™ saunas will be mostly below 1mg when tested directly on the heater itself. Where you are sitting in the sauna, the EMF levels are virtually 0mg. The ELF levels in your Clearlight Infrared Sauna™ are 3 – 5 times below the threshold of concern. All of our competitors are over 20 times above the threshold of concern.
