ABSTRACT:
A high efficiency particulate air filter is disclosed which has a channel formed in the front peripheral surface thereof, with the channel being substantially filled with a sealant which comprises an essentially non-volatile and non-hardening gum-like material. The physical properties of the sealant render the sealant able to effect sealing engagement with a mating flange mounted in the filter housing, and also permit the flange to be withdrawn from the sealant without an appreciable amount of the sealant adhering to the flange, to thereby avoid the build up of potentially contaminated sealant on the flange when the filter is changed. A method of fabricating the filter is also disclosed, which results in the sealant forming a substantially uniform and continuous closed strip which is characterized by the absence of a butt end joint.
