Abstract

Amongst other things, there is provided an air filter that is for use in a duct having one or more walls. The air filter comprises a peripheral frame that includes a substantially resilient and compressible casing, and a substantially rigid internal skeleton within the casing. The air filter also comprises a filter element attached about its entire perimeter in sealed relation to the casing of the peripheral frame. The filter element is adapted to remove contaminants from air passing through the duct. When the air filter is in use, it is positioned in the duct such that the casing of the peripheral frame is compressed against the walls of the duct in substantially air-sealed relation therewith.

Claims (13)

1. An air filter for use in a duct having one or more walls, said air filter comprising:

(a) a peripheral frame comprising a substantially resilient and compressible casing and a substantially rigid internal skeleton within said casing; and, (b) a filter element attached about its perimeter in sealed relation to said casing of said peripheral frame, wherein said filter element is adapted to remove contaminants from air passing through the duct;

wherein, when said air filter is in use, said air filter is positioned in the duct such that said casing of said peripheral frame is compressed against the walls of the duct in substantially air-sealed relation therewith.
2. An air filter according to claim 1, wherein said filter element is centrally positioned within said peripheral frame.
3. An air filter according to any one of Claims 1 to 2, wherein said air filter is washable.
4. An air filter according to any one of Claims 1 to 3, wherein said casing has an inwardly directed face and an outwardly directed face, and wherein said outwardly directed face abuts the walls of the duct when said filter is in use.
5. An air filter according to any one of Claims 1 to 4, wherein said internal skeleton includes one or more side segments.
6. An air filter according to claim 5, wherein adjacent ones of said side segments of said internal skeleton frame are contiguous with one another.
7. An air filter according to any one of Claims 1 to 6, wherein said casing is comprised of one or more filter media.
8. An air filter according to claim 7, wherein said casing and said filter element are both comprised of the same filter media.
9. An air filter according to any one of Claims 1 to 8, wherein said filter element has a plurality of pleats formed therein, each comprised of a plurality of fold lines and two adjacent sloping side surfaces.
10. An air filter according to any one of Claims 1 to 9, wherein said filter element is glued to said peripheral frame.
11. An air filter according to any one of Claims 1 to 9, wherein said filter element is stitched to said peripheral frame.
12. An air filter according to any one of Claims 1 to 9, wherein said filter element is releasably attached to said peripheral frame.
13. An air filter according to any one of Claims 1 to 12, wherein said filter element is attached about its entire perimeter to said casing of said peripheral frame.
