An ozone generator includes a housing with a plurality of openings and containing an ultraviolet lamp and a blower. A control is remotely connected to the housing for turning the generator on and off. The ultraviolet lamp emits ultraviolet radiation. The blower moves air into contact with radiation from the ultraviolet lamp. A modular arrangement of the invention includes components for assembling an ozone generator. The arrangement includes a first generator component and a second generator component connected by a hose. Another embodiment of a modular arrangement includes a generator and a blower connected by a hose. A method for operating an ozone generator includes placing an ozone generator in an unoccupied, enclosed space; placing a controller that is connected to the generator outside of the enclosed space; and turning on the controller.
