Abstract

A filter element having a frame defining an interior volume and having exterior surfaces. Filter media is mounted within the frame so as to allow fluid to enter an upstream side of the media and exit a downstream side of the media. At least one component of a multi-component filter frame seal, the at least one component being positioned on an outer surface of the frame and substantially circumscribing the filter frame at a location selected to align to a complementary component of the multi-component filter frame seal. The complementary component is provided separately from the filter element.
