An attachable air vent filter assembly for attachment to an air vent register of a HVAC system located in an interior space comprising:
- a filter housing having sidewalls and an open top;
- said sidewalls being adapted to fit over the vent register;
- a removal filter carried within said housing having a filter medium for filtering air exiting from said vent register;
- at least one attachment member for securing said filter housing above said vent register in the direction of airflow;
- at least one air exit opening in the top of said housing for delivering air filtered by said filter medium directly into said interior space;
- wherein at least one of said sidewalls includes a perimeter housing flange that fits over a vent register flange to effectively cover said vent register;
- and
- wherein all said housing flanges include a contoured lip covering an outside edge of said vent register flange.
An attachable air vent filter assembly for attachment to an air vent register of a HVAC system, said HVAC system being of the type having an air duct box, and air vent register having a register box received within said air duct box, a plurality of air openings disposed on a top of the register for delivering conditioned air into a living or workspace, and a HVAC air filter filtering air prior to delivery to said air vent openings, said air vent filter assembly comprising:
- a filter housing having sidewalls a housing flange extending from said sidewalls, and a top co-extending with said sidewalls;
- said housing sidewalls and flange being adapted to fit over the vent register;
- a removable filter medium carried by said housing for filtering the condition air a second time before exiting into the room;
