An air gasper knob system for an overhead Passenger Service Unit (PSU) (10) includes an annular gasper knob (102) of a UV transparent material. The annular gasper knob defines an air passage (108) therethrough, and extends about the air passage from a first annular end face (104) to a second annular end face (106). The system also includes a UV illuminator (110) mounted to the gasper knob, oriented to transmit UV illumination through the UV transparent material to sanitize exterior surfaces of the gasper knob. A method of sanitizing an air gasper knob comprises illuminating a gasper knob in an overhead PSU using UV illumination to destroy infectious agents on surfaces of the gasper knob.
