The infrared frequency of a far infrared heater is determined by the surface temperature of the heater itself. The lower the surface temperature of the heater, the longer the infrared wave and the more beneficial the infrared heat will be.

Our large True Wave™ far infrared heaters run at an optimal 180-200°F surface temperature producing exceptional quality far infrared heat. This means our heaters produce the majority of the infrared heat in the vital wave range of 6 to 12 microns with a good portion of wavelengths at 9.4 microns, the optimal absorption range of far infrared by the human body.

Only our True Wave™ heaters combine the high infrared output of ceramic with long wave carbon infrared heat to produce the most effective infrared heaters available. You can only find this combination in Jacuzzi® infrared saunas!

Our True Wave™ Full Spectrum infrared heaters are powerful 500 watt heaters that produce near, mid and far infrared. Adding in full spectrum therapy to your Clearlight Sauna® will enhance the benefits if our far infrared heaters. You will get more benefit faster in a full spectrum infrared sauna.
