Abstract: A bathroom mirror defogger includes a translucent spherical psuedo light bulb-type housing having an electric plug base extending therefrom along the central axis of the housing and adapted to be screwed into a lamp socket in a light bar immediately juxtaposed to a side and/or top edge of a bathroom wall mirror. The housing is provided with an air inlet and an air outlet and encloses an electric heating coil and motor driven fan. The air outlet is positioned laterally of the central axis on a portion of the housing rotatable about the central axis so that the orientation of the outlet can be adjusted relative to the mirror surface. The fan aspirates air through the inlet across the heating coil and pumps the resultant warmed air out through the outlet and against the mirror surface to remove or prevent moisture condensation thereon from a shower or hot water present in the bathroom.
