An air filter including a generally tubular filter element having an open air outlet end and a closed end is provided with a molded ring-like end cap of a soft elastomer material. A tubular air outlet member is mounted in the open end of the filter element with the end cap having a radially inwardly facing surface constructed so as to be compressed to sealingly engage the outlet member to block flow of contaminated air therebetween. A housing having an air inlet surrounds the filter element to provide an air distribution chamber for incoming contaminated air.
