A Cedrus Sauna produces five to thirty times the infrared of any other sauna on the market. Not only do we produce more of this safe, healing light, we do it at a better wavelength. This allows your body to absorb more far infrared in less time and at a lower temperature than any other infrared sauna. This is made possible by our patented heater design found only in a Sauna built by Full Spectrum International Inc.
