1 gross Air filter, disposable fiberglass, no support, EZ Flow II, 14 x 24 x 1 Inch

Frame is made from heavy, moisture-resistant chipboard in a one-piece design that eliminates corner separation. * Filtering media is progressive density, continuous filament spun glass. A resinous bonding agent provides rigidity and resistance to compression. A viscous adhesive increases filtering effectiveness. * These filters have been tested by Underwriters Laboratories Inc., and classified as Class 2 for flammability. ? Instead of a metal media retainer, a very fine spray of fiberglass is blown onto E-Z Flow II¡äs media surface fibers. That creates a tough mesh on both faces of the filter media. This mesh takes the place of the metal grill to provide structural integrity.
