Abstract: A filter unit for use with a clothes dryer for filtering the exhaust and selectively directing the exhaust to the outside or inside of a building. The filter unit supports a filter element in a slanted position so that when installed between the studdings of a building the filter unit does not extend an appreciable amount beyond the surface of the wall and still provides for large capacity filtering. A removable cover makes for easy access to the filter element. The filter housing is made of sheet material which has reinforced walls. An indicator is used for indicating the condition of the filter element.
