ABSTRACT:
A high efficiency filter assembly having a generally rectangular pleated filter element with ends defined by the pleated edges of the element and sides defined by generally planar side edges of the element. The filter element is mounted in a generally rectangular housing formed by two pairs of oppositely disposed frame members that are joined together. Each frame member has a planar base member and a pair of upright side member defining an open ended channel to receive the ends and sides of the filter element. At least one spacing member extends along the base portion to space the ends and sides of the filter element from the surface of the planar member. A dam member is provided at each end of one of the pairs of planar members to enclose the channel, and a sealant is disposed in the channel and the ends of the filter element are embedded in the sealant.
