An ozone generator that serves the double functions of providing a light source and providing ozone is disclosed. Particularly, the ozone generator may be located in a generally closed appliance, such as a refrigerator, dishwasher, clothes washer or drier or the like. In addition, a stand-alone embodiment is disclosed that may simply be mounted or placed in storage or other areas such as closets, pantries, laundry rooms, clothes hampers, bed linen storage trunks and others. In some embodiments, timers are used to periodically raise ozone levels to relatively high levels and then allow the levels to fall, sanitizing and deodorizing the areas within which they are located. In other embodiments, advanced oxidation techniques are used by using a pair of ultraviolet tubes, one emitting radiation at a wavelength of 185 nm and the other emitting radiation at 254 nm.
