Air register filter/cover
First Claim
1. Apparatus for use in combination with air handling equipment having a central blower means coupled to a ductwork system including a plurality of inlet and outlet ports, comprising:
- a) filter means comprising a media porous to the passage of air therethrough, yet trapping airborne particulates; and
b) a multi-walled framework defining a cavity between at least a fore and an aft wall, wherein said fore and aft walls include a plurality of apertures and wherein said framework includes;
1) means for removably mounting said filter means within said cavity,
2) means for restraining said framework to the ports of said ductwork system, and
3) means for selectively covering ones of said apertures to prevent airflow through said framework.

Abstract
A disposable filter for heating and ventilating registers wherein a supporting framework includes apertures with removable cover portions which permit selective air flow, means for securing the framework to the register or adjacent structural members and re-closable means for admitting a filter element to an interior cavity. In alternative configurations, differing filter media or replacement media may be mounted to the framework. A separately attached border trim may also be included for oversize registers. Also considered is a finish cover including means for retaining the filter to the cover and the cover to the ductwork port.

10. A replaceable filter element comprising:
-
a) a filter media having a porosity sufficient to permit airflow therethrough; b) support means for containing said filter media comprising a multi-walled container formed from a sheet goods material to include a plurality of scribed horizontal fold lines and first and second scribed end flaps, whereby said sheet goods can be folded into a multi-walled container having an interior cavity defined between first and second re-closable end flaps thereto, wherein a first surface of said container includes a plurality of apertures, and wherein a second surface of said container includes a plurality of partially scribed regions, said partially scribed regions defining removable covers, whereby airflow is prevented while said covers are attached and airflow is permitted when said covers are removed, and wherein ones of the walls include a plurality of scribed mounting tabs, whereby said mounting tabs can be detached and bent to project from the housing to restrain the housing to one of said ductwork ports. - View Dependent Claims (11)
