Abstract
A panel filter is provided such as for HVAC applications in which one of the cut edges is frayed and attached with adhesive to the inner peripheral surface of a paper board frame. The frayed edges may facilitate better gluing of pleated filter medium to the frame especially for self-supported filter media applications and may increase structural rigidity and sealibility as a whole. Frayed edges also provide flexibility to assist in installation of a card of pleated filter medium into a paper board frame.
