Abstract
A filter assembly has an annular outer wall with a channel for receiving a layer of adhesive and a center ring within the outer wall. A filter media having a plurality of pleats in a closed loop is bonded with adhesive to the outer wall. The assembly is made by rotating the outer wall in a jig and applying a layer of adhesive within the channel. The filter media is positioning the within the outer wall, rotated and allowed to move along a radial path until its outer perimeter contacts the adhesive coated outer wall inner perimeter. The ring is positioned adjacent the filter media inner perimeter.
