The EZ flow disposable panel filter is designed for protection of furnace and central air units in residential and light commercial applications. The 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 media is continuous filament spun glass. A resinous bonding agent provides rigidity and resistance to media compression. Media support is provided by a bottle cap retainer on the downstream side.
