Filter with covered edges

摘要

A filter insertable into an air filter enclosure includes a flexible support member, a filter media layer, and a pair of end caps. The filter media layer is attached to the support member. Side edges of the filter media layer are folded over edges of the support member to form filter cushions, such that the filter media layer covers the edges of the support member. The filter cushions are designed to conform to the air filter enclosure to ensure an effective seal between the enclosure and the filter.
