MERV 8 Return Air Grill Filters - Featuring a "Knife Edge Seal"
Return Air Grille Filters are pleated residential replacement filters designed to fit existing air filter grilles in your home or workplace. They are designed with a 5" filter depth that provides 9 times the media area of a comparable 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 installations. Return Air Grille Filters are offered in MERV 8, 11, 13 and carbon media for odor control.
When you change out your regular 1” filter put one of these into the return air grill and forget about it for 6 months to a year! Changing your air filter less frequently is one less thing to worry about.
