Abstract

A disposable air filter that includes: (a) air filtration media; (b) a substantially planar air filter frame providing three-dimensional support for the air filtration media; and (c) an inter-filter gap filler disposed along substantially the entire length of at least one side of an opposed pair of the first or second sides and integrated into the air filter frame is disclosed. The integral inter-filter gap filler reduces gaps between adjacent air filters disposed in a filter track of an air filter bank.
