Abstract: A filter mechanism is disclosed which is designed to be used with a clothes drying machine for filtering the exhaust of the clothes drying machine, and for directing said exhaust either into the interior of a building or to the exterior of a building. The mechanism includes a disposable flexible filter element, a cylindrical body that supports and holds in place the flexible filter element, a rectangular enclosure to contain the cylindrical body and filter, and a means of directing the exhausted air into the interior or to the exterior of a building. The cylindrical body, in addition to holding the filter element in place, comprises one end of the rectangular filter mechanism and provides a means of removing the filter element for replacing of the flexible filter element. This said end comprises the inlet to the filter which may be connected the clothes drying machine. Openings on the rectangular housing provide the means for directing the exhaust into the interior or to the exterior of the building.
