Abstract
An antimicrobial air filter has a layer of fabric bearing porous activated carbon particulate deodorizing agents, a layer of polymeric expanded foam filter media impregnated with a biostat type antimicrobial agent and a pleated sheet of HEPA filtration media treated with the biostat. The layers are assembled such that the biostat does not migrate into the porous carbon particulates. The filter may be used in central air conditioning and heating systems without the need for an air circulator in addition to those conventionally employed.
