Our system is an "active" system and works differently by using and advanced form of photocatalytic oxidation (PCO) technology (originally used by NASA to provide safe air for astronauts aboard the International Space Station. Our Puraclenz powered active system produces an unprecedented volume of positive and negative ions for a PCO device resulting in greater cleaning coverage in a typical indoor setting thereby deactivating pathogens not only in the air around us but also that manual cleaning may have missed. PCO is a process similar to the one that occurs naturally when UV rays in sunlight react with air molecules in the atmosphere after a lightning strike. Unlike traditional ion generation systems that generate harmful levels of VOC's, independent laboratory studies show that VOC's measured were at least 35 times below the OHSA permissible exposure limits standard for safe use around people.
