An apparatus and method for deodorizing a gas mixture including air and a malodorous substance having a flow passage for the gas mixture and a fan for inducing air flow in a predetermined direction through the passage. An ultraviolet lamp for generating uv rays below a critical wavelength is in the flow passage for generating ozone from the air in the gas mixture. An ozone-decomposing catalyst layer is in the passage for contacting the gas mixture, and an ozone-decomposing ultraviolet lamp for generating uv rays above critical wavelength is positioned to irradiate the layer directly. The intensity of the radiation of the two layers is controlled to avoid the discharge of ozone from the downstream end of the passage. |
