ABSTRACT:
Disclosed is a device for demisting the surface of a bathroom mirror using hot air supplied by a portable hand-held hot-air blower, and including air-conducting apparatus having duct elements that are detachably mounted along the perimeter of the mirror surface using suction cups or the like. Each duct element has a plurality of spaced-apart nozzles or apertures, and a tubular inlet member is pivotally attached in flow communication with the air-conducting apparatus, and is adapted to slidably and removably receive the tubular exhaust nozzle of the portable blower such that hot air supplied by the blower will exit the duct nozzles and move across the surface of the mirror so as to remove water condensate from the mirror surface.
