Abstract
Disposable air filter includes a filter element formed from a stacked plurality of annular disks. The disks are formed from a sorptive material and expand upon absorption of oil or water droplets. The disks are slightly compressed by a movable baffle. The baffle floats upon a stream of air entering the filter and directs the air radially through the filter element. The air flows between and through the disks with a resulting low pressure drop across the filter. As the disks expand, the baffle shifts axially within a filter housing to maintain the pressure drop across the filter element.
