The rectangular filter flange assembly has a central aperture open to an interior region bounded by the filter element. The rectangular filter flange assembly includes a pair of short edges and a pair of long edges. A gasket is disposed on a top surface of the rectangular filter flange assembly circumscribing the central aperture. A first portion of the gasket is outward of the filter element in a direction toward the one of the short edges, and a second portion of the gasket is over the filter element in direction toward one of the long edges.
