Summary:A filter pocket arrangement (44) that provides increased filter media area is described. In one embodiment, each filter pocket (90) includes a pocket mouth (92) that attaches to a filter frame (80) and a pocket body extending longitudinally away from the pocket mouth (94) to a closed end (96). The closed end is folded back inward towards the pocket mouth (94) to form a tuck fold (98) that defines a first sub-filter pocket (100) and a second sub-filter pocket (102) at the pocket mouth (94). The first sub-filter pocket(100) and the second sub-filter pocket (102) each has a sub-pocket mouth (94) that coincides with a portion of the pocket mouth, with sidewalls (106) extending longitudinally therefrom to form an apex (108) at the closed end (96) of the filter pocket. The first sub-filter pocket (100) is separated from the second sub-filter pocket (102) by the tuck fold (98).
