Abstract: The disclosure describes an arrangement which comprises a porous filter layer and a porous support layer. The porous support layer has first and second surfaces and the porous filter layer is positioned near the first surface of the porous support layer. The filter arrangement further comprises several polymeric beads disposed in parallel strips on the second surface of the porous support layer. The filter arrangement is corrugated to form pleats which extend generally perpendicular to the polymeric beads. Each pleat includes an open end, a bight end, and first and second opposing sides which extend between the open end and the bight end and include a portion within each pleat in which the opposing sides are in essentially parallel relationship. Each bead extends from the open end of the pleat along the first side to the bight end and from the bight end of the pleat along the second side to the open end. The portions of each bead which extend along the opposing sides of the pleat are joined to one another.
