Economy Fiberglass EZ Flow II disposable filters are 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
The filtering media is continuous filament spun glass
A resinous bonding agent provides rigidity and resistance to media compression
The EZ Flow II 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
Sealing is accomplished with a resilient hot-melt adhesive running the full perimeter of the frame on both upstream and downstream sides
