Abstract

An apparatus for the filtration and decontamination of air flowing through an air stream through which a mechanical filter media is continually decontaminated and sterilized as it continues to remove airborne contaminants in said air stream. The air and airborne contaminants are subjected to high frequency ultraviolet light, destroying organic airborne materials. Said ultraviolet light will react with a surface coating of a photo-catalytic substance within the apparatus to create hydroxyl-radicals to bond with, and destroy organic airborne contaminants. Additionally, the configuration of said apparatus is effective in the removal and destruction of smoke and organic gases.

Claims
