Abstract: An apparatus that directs the flow of heated air that is being discharged from a clothing dryer, in which the dryer is positioned upon a rigid support, that elevates the dryer above the normal ground surface. The dryer discharge hose is connected at one end to the dryer, and to a valve assembly, located beneath the dryer, housed in the dryer support. The valve may be actuated so that heated air is either directed to flow through the valve assembly, into another hose which vents directly outside, or through an interior discharge opening, so that heated air is reintroduced back into the dwelling. The apparatus is provided with an access door, so that the valve can be positioned as desired. If air is being reintroduced back into the dwelling, a removable air filtration system is provided. In the event that the air filtration system becomes overwhelmed with particulate matter, the valve has a safety flap which is actuated by increased air pressure, and allows the heated air to vent outside.
