ABSTRACT:
A device for recovering and using the hot, moist air exhausted from a clothes dryer is disclosed. The device includes a housing having a supply inlet, an exterior vent outlet and a heating outlet. Valve means are provided for selectively closing off the vent outlet so that hot, moist air may pass from the supply inlet to the heating outlet. A staged filtration system is supported within the housing for filtering the lint and other particulate matter from the hot, moist air as it passes from the supply inlet to the heating outlet. The heating outlet is connectable to an existing heating duct or the device may be vented directly into the interior of the building within which it is used.
