Abstract
Air filter with a sidewall and inverted cone cap sections; a beveled crown unifying the sidewall with the cap to form a one-piece filter; a seat on the bottom of the wall section with seals for contact with a support; and a flange affixed to the cap to adjust contact with a support surface. The filter media includes four-layer oleophilic cotton mesh layers supported between two structural mesh layers, with an efficacious amount of oil to increase particle trapping.
