Abstract
Abstract A filter assembly (10) adapted to be secured to a register (18) of the type used for covering a forced air duct outlet (12) in heating/cooling systems is disclosed. The filter assembly (10) removes contaminant particles from air flowing through the forced air duct outlet (12). The filter assembly (10) includes a filter material (33) of permeable and pliable material and an elastic band (34) secured to the filter material (33) for clamping the filter material (33) to the exterior surface (27) of the register skirt (26).
