A thin illuminated sign is described which is formed of two essentially mirror image frame members at least one of which has a central opening therethrough to expose a translucent sign element including signage indicia associated therewith. The frame elements contain mirror image mounting members adapted to support therein a mounting channel for a cold cathode florescent tube along at least one of the edges of the translucent member for projecting light therein.

An air disinfection method and unit are disclosed in which air is passed through a housing from an air inlet to an air outlet opening at a predetermined air flow rate under substantially uniform cross-sectional air flow conditions across closely spaced UV-C irradiation lamps located at a distance of between 2 to 4 inches O. C. with the lamps being positioned directly in the air stream so that all air flows passed the bulbs at a distance of not more than 2-3 inches. The bulbs produce UV-C irradiation at a wave length of about 254 nm and have an intensity of about 142 .mu.W/cm.sup.2. The housing has a predetermined volume selected such that airborne bacteria remain in the enclosure for a residence time of between 0.5 and 1.5 seconds.
