PUROH is a new industrial purification technology that allows for the elimination of microorganisms and volatile organic compounds in the work environment. Unlike passive ventilation and filtration methods, PUROH is an active technology that uses a chain reaction of neutral hydroxyl OH· radicals to mineralize volatile organic compounds into harmless substances like oxygen, water, or soluble carbonates. Additionally, PUROH technology can also prevent the spread of diseases in areas with employee contact since it is lethal to microorganisms. PUROH is available in different devices adapted to each environment and offers the versatility of being able to be incorporated into any ventilation duct. The technology is FDA and EU Medical Device certified.
