Return Air Grille Filters residential replacement filters are designed to fit existing air filter grilles. Return Air Grille Filters are designed with a 5" filter depth that provides 9 times the media area of a comparible 1" filter, which greatly reduces pressure drop while increasing service life. Return Air Grille Filters utilize a unique knife edge seal header to prevent bypass, and can last 6 months to a year in most home installations. Return Air Grille Filters are offered in MERV 8, 11, 13 and fume control ratings.
The Return Air Grille Filter from Quality Filters offers superior performance and lower air resistance by greatly increasing media surface area as compared to a 1” traditional filter. “Knife-edge seal” header design prevents dust bypass by pressure fitting into the frame.
