ABSTRACT:
An air filter housing slidably receives an air control insert therein without requiring the air filter housing to be removed from the wall, floor or ceiling surrounding an air duct. The air filter housing varies in size in at least one dimension to reduce the quantity of air filters and air filter housings required to accommodate a wide variety of air duct types and sizes. The housing is mounted to a register, diffuser or return air grill covering an air duct. The air control insert is slidably received in the air filter housing for ease of removing, cleaning or replacing. The housing is adaptable to receive a variety of inserts which are custom designed to remove specific pollutants from the air to improve the air quality in a home or office, or to block the flow of air entirely.
