ABSTRACT:
Indoor pollutants such as formaldehyde can be removed from a home reactive method consisting of a coating on a furnace filter in a forced air heating system. The coating is a polymeric substance with specific functional groups which react with the pollutant and which in the case of formaldehyde or other aldehydes such as acrolein or acetaldehyde would be a polymeric amine such as polyethylenimine.
