Abstract
An apparatus and method for filtering air in residential and commercial applications is described herein. The air filter may have a support frame which secures to the intake grille of an HVAC system. A filter media may be placed in the support frame to filter air as it passes through the air filter. The filter media may be replaced when the filter media becomes too dirty to effectively filter air. The dirty filter media may be removed from the frame and a new clean media may be replaced in the frame.
