ABSTRACT:
An air filter kit for residential and light commercial air filtration applications including a user assembled, dimensionally adjustable, air filter frame assembly capable of telescopic adjustment of both length and width. Telescopic adjustment is facilitated by a plurality of slidably engaged frame members which together form an adjustable peripheral filter frame defining a recessed channel for receiving a quantity of filter media therein. Adjustment of the frame members is further facilitated by the use of a lubricating substance such as a friction reducing synthetic tape between the members. A quantity of spongy filter media is secured cut to size and secured within the recessed channel by a quantity of hook material projecting into the filter media. A perimeter gasket anchors the frame dimensions while providing a positive seal between the frame and a filter track.
