A filter element includes a frame construction and a region of media held by the frame construction. The region of media is oriented within the frame construction to remove at least some particulates from a gas stream passing therethrough. The region of media includes a skirted portion, wherein the skirted portion occupies a volume between the frame construction and a sealing surface of a duct, when the filter element is mounted within a duct. In preferred systems, the filter element may be used as a secondary element in the duct of an engine air intake or in a duct of an air cleaner housing. Methods of using and servicing filter elements are described herein. |
