As the oldest and largest US manufacturer of saunas and steam rooms, we are intimate with the treacherous ecology that exists in commercial steam rooms. Unlike saunas (dry room at 180 degrees), steam rooms are warm (115 degrees) moist environments, the ideal environment for the proliferation of mold, bacteria and viruses. For years, commercial operators waged their daily war against these conditions with a regiment of toxic chemicals but with little success. In 2012, we developed and introduced the Powerzone product line as a simple and highly effective way to sterilize their steams rooms. For the past eight years, we have been eliminating viruses in hundreds of commercial fitness facilities within the most demanding environments. We are now bringing this technology to our everyday living space.
