AIR FILTER ASSEMBLY Abstract of the Disclosure An air filter assembly is provided which comprises a multisided air filter panel and a multisided supporting frame therefor. The frame is of unitary construction and includes a foraminous center section, and a marginal section delimiting the center section. The center and marginal sections are in supporting engagement with one surface of the filter panel. The frame is provided with a plurality of peripheral sections which are foldably connected to the marginal section and cooperate with one another to delimit the center and marginal sections. Each peripheral section includes foldably connected first and second flange segments which are disposed in substantially face-to-face fold back relation. The first flange segment is foldably connected to a portion of the marginal section and extends angularly inwardly therefrom and forms an acute angle with the portion of the marginal section to which it is attached. A third segment is foldably connected to the second flange segment and extends angularly therefrom. Tabs are foldably connected to the ends of the second flange segments of alternate peripheral sections and when the frame is set up in assembled relation the tabs become automatically aligned with and inserted into adjacent pockets formed by the adjacent first and second flange segments of the adjacent peripheral section. A peripheral portion of the filter panel is secured in sandwiched relation between the marginal section and the third segment of each peripheral section. The construction of the frame enables the filter assembly to assume a collapsed state so that a plurality of such assemblies can form a compact bundle for shipping and/or storage.
