How does it work?
Units with ActivePure Technology pull free oxygen and water molecules in the air through ActivePure’s patented honeycomb matrix. The technology creates powerful oxidizers, known as ActivePure Molecules, that are then released back into the room, where they seek and destroy DNA and RNA viruses including SARS-CoV-2 (novel coronavirus), Swine Flu (H1N1), Avian Bird Flu (H5N8), Hepatitis A (HAV) and MS2 bacteriophage, regardless of their size, on surfaces and in the air.
