Flanders EZ Flow II 10055.012025 Furnace Air Filter, 20 in L, 25 in W, 4 MERV, Chipboard Frame
Promo Price:
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. Polystrand fiber (PSF) continuous polyester media is also available. PSF media provides added strength, resistance to moisture and improved efficiency.
