difference between ceramic and carbon fiber, which is better? thanks

Hello Raymond and thank you for your question. There is a good comparison between ceramic infrared sauna heaters and carbon fiber infrared sauna heaters on this page: http://www.saunasandstuff.com/ceramic-Infrared-sauna-vs-carbon-fiber-infrared-sauna/ It is generally thought that Carbon fiber panel heaters are better. They are the newer style, provide a more evenly spread out pattern of infrared rays, and allow for a heater in the floor. At this point, probably 99% of our infrared sauna sales are the carbon fiber models.
