摘要
A high efficiency air filter having a channel formed in the front peripheral surface thereof which is substantially filled with a fluid of high consistency and which is adapted to effect sealing engagement with a mating retaining flange mounted in the housing. A pair of resilient wiper lips extend across the top of the channel from opposite sides thereof to thereby contact the sides of the retaining flange while the filter is assembled in the housing, and then wipe both sides of the flange during withdrawal of the filter from the housing to thereby retain substantially all of the fluid within the channel and prevent the build-up of possibly contaminated fluid on the retaining flange.
