A fan blade, preferably for use with a ceiling fan, is constructed hollow with a top and bottom located so as to provide an air space sufficiently large enough to house one or more germicidal lights, preferably ultraviolet, in such manner that the light will burn while the fan blade rotates. Filtering pads, preferably charcoal impregnated and usually comprised of a plastic foam, are located at the leading and trailing edges of the air space between the top and bottom of the hollow blade for the absorption of smoke and other objectionable odors as the air passes through the lamp area. Preferably the leading edge is provided with pocket means to receive the air. Baffles may be provided to prevent the germicidal light from casting its light outside the confines of the hollow blade. The ends of the blade joining the leading and trailing edges thereof are closed. By virtue of all of the foregoing the hollow fan blade containing the ultraviolet germicidal light is rotated at a speed...
