Abstract:
A system for circulating air which includes particles, bacterial organisms, and odoriferous material includes a fan coupled to ducting of the air circulation system for causing movement of air in a stream through the ducting; a filter holder configured to hold an air filtering device supported within the air stream; and an air filtering device for removing from the circulating air the particles, bacterial organisms, and odoriferous material. The air filtering device may include multiple filter elements having multiple layers of differing filtering materials, which may include activated carbon and potassium permanganate. Also disclosed is an air filter for use in an air circulation system, comprising a housing, a first filter element configured to remove odoriferous materials and larger particles from the air, a second filter element configured to remove the remaining smaller particles from the air and to neutralize bacterial organisms, and a reticular support member interposed between and substantially in contact with the first filter element and the second filter element.
