As you have indicated, the IR sauna industry is very full of competition currently; however, I would recommend reviewing the Low EMR/Low EF saunas manufactured by Saunatec and sold through Finnleo and Helo Dealers. The models that will interest you are the B and S series, as their EMR and EF ratings exceed the stringent Swedish standards for safety. Both utilize CarbonFlex technology for the emitters, and the S series offers upgrades, like an all glass front and a touch screen control with radio/MP3 integrated. To learn more, you can visit http://www.finnleo.com/products/far-infrared-sauna/ and http://www.finnleo.com/blog/. Helo offers the same product, so if you wanted to see your closest dealer for Helo, you can visit, http://www.helosaunas.com. Be sure to ask for the B or the S series, as there are lower priced units available, which are safe, but they do not feature the low EMR/low EF. There are some competitors who build quality units who have done well at limiting EMR or EF, but Saunatec has accomplished the task of exceeding the toughest safety standards.
