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.
Claims18
An antimicrobial air filter comprising a layer of fabric bearing porous activated carbon particulate deodorizing agents and a layer of polymeric expanded foam filter media impregnated with a biostat type antimicrobial agent, said fabric layer being separated from said foam layer such that said antimicrobial agent is substantially prevented from contacting said porous activated carbon particulate deodorizing agents and clogging the carbon pores.
An antimicrobial air filter comprising a pleated sheet of HEPA filtration material comprising glass fibers treated with a biostat type antimicrobial agent and a layer of fabric bearing porous activated carbon particulate deodorizing agents mounted adjacent said pleated sheet.
An antimicrobial air filter comprising 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 layer of HEPA filter media located adjacent said layer of fabric, said fabric layer being separated from said foam layer such that said antimicrobial agent is substantially prevented from contacting said porous activated carbon particulate deodorizing agents and clogging the carbon pores.
