EZ Flow II 10055.012036 Air Filter, 20 in L, 36 in W, 4 MERV, Chipboard Frame

The EZ Flow II filter is made to function without a retainer by adhering the frame directly to the media, which has a light skin to make it self-retaining. The EZ Flow II frame is made from heavy chipboard in a one-piece design that eliminates corner separation. Sealing is accomplished with a resilient hot-melt adhesive running the full perimeter of the frame on both upstream and downstream sides. The EZ Flow II fiberglass media is continuous filament spun glass. A resinous bonding agent provides rigidity and resistance to media compression.
