Abstract: Filter assemblies with adhesive attachment systems are provided. In one embodiment, a filter assembly includes a porous filter member and an adhesive disposed on a reinforcement scrim adhesively attached to at least a portion of at least one major surface of the porous filter member, wherein the reinforcement scrim has discrete open areas. In an alternative embodiment, a filter assembly includes a porous filter member that includes fibrous filter media and an adhesive impregnated into discrete regions of the porous filter member such that there is a substantially continuous adhesive region throughout at least about 25% of the thickness of the porous filter member in the discrete regions.
