摘要： A pleated filter element comprising a pleated filter media comprising a plurality of oppositely-facing pleats with a pleat direction and with a plurality of upstream and downstream pleat tips and pleat valleys, wherein the pleated filter media comprises two corrugated edges and two noncorrugated edges. The first (second) corrugated edge of the pleated filter media comprises an edge dam of hardened adhesive that occupies the upstream and downstream pleat valleys at a location laterally inwardly proximate the first (second) corrugated edge and that extends along an entire longitudinal extent of the pleated filter media. The pleated filter media is a multilayer media comprising an organic polymeric nonwoven web, that exhibits a Percent Penetration of less than 5, laminated with a fiberglass prefilter layer that is disposed upstream of the primary filtration layer and that exhibits a Percent Penetration of greater than about 70.
