Abstract
A process for using photocatalytic load reduction to extend reactive media filtration life is disclosed for an air purification system. The system consists of three methods of cleaning the air including a UV light, a photocatalyst, and an air purifier. Air first passes through a portion with the UV light and photocatalyst, and then through the purifier. Passing the air first through the UV light and photo catalyst before the purifier reduces the load on the purifier and thus allowing the purifier to operate and clean the air for an extended period of time as compared to the purifier alone.
