Abstract
A high efficiency air filter for use in a standard return air grille is provided. Standard return air grilles possess filter receptacles for accepting air filters, a closeable cover with a cover flange for engaging air filters and a duct interface that leads away from the air grille to the remainder of the return air ducts. The air filter has a filter flange with a gasket that is sized to fit within the filter receptacle of the air grille, such that when the cover is closed, the cover flange seals against the cover and the filter receptacle. The gasket is affixed to a housing that is sized to extend beyond the filter receptacle into the duct extending beyond the return air grille. An extended pleat air filter is contained within and sealed to the walls of the housing such that air passing through the return air grille substantially passes through the air filter prior to entering the remainder of the return air duct.
