A filter pocket arrangement that provides increased filter media area is described. In one embodiment, each filter pocket includes a pocket mouth that attaches to a filter frame and a pocket body extending longitudinally away from the pocket mouth to a closed end. The closed end is folded back inward towards the pocket mouth to form a tuck fold that defines a first sub-filter pocket and a second sub-filter pocket at the pocket mouth. The first sub-filter pocket and the second sub-filter pocket each has a sub-pocket mouth that coincides with a portion of the pocket mouth, with sidewalls extending longitudinally therefrom to form an apex at the closed end of the filter pocket. The first sub-filter pocket is separated from the second sub-filter pocket by the tuck fold.
