Abstract: An improved disposable filter cartridge for use in a filter housing includes a pleated filter member and first and second plastic end caps mounted to the ends of the filter member. The first end cap has an inner edge defining a central opening. In one embodiment, an elastomeric annular gasket is removably mounted to the inner edge of the first end cap. In another embodiment, a predetermined surface of elastomeric annular gasket is adhered to a confronting surface of the first end cap. At least one annular ridge projects into the first end cap opening. The at least one ridge abuts the outer surface of an inlet tube to form a fluidic seal with the inlet tube when the disposable filter cartridge is mounted within a cooperative filter housing. The second end cap may include an elastomeric annular gasket having an angled sealing surface configured to form a seal against the confronting end of an inlet tube.

Abstract: An air filter comprising an elastomeric flange member and a filter member mounted therein. The flange member has opposing ends and sides that define a central opening and protruding members integrally formed with the flange member and extending therefrom. The protruding members have opposed inwardly facing faces. The filter member has filter ends and sides and the filter sides are attached to the opposed faces in an insert molding process or via bonding of the filter sides to the respective faces.
