This product uses high energy and high ozone UV ultraviolet light beam, oxidation reaction catalytic plate, high energy ion generator process to degrade malodorous gas (organic waste gas), and change malodorous gases such as ammonia, trimethylamine, hydrogen sulfide, methyl sulfide, methyl mercaptan. The molecular chain structure of methyl sulfide, dimethyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC, benzene, toluene and xylene, so that the molecular chain of the organic or inorganic polymer malodorous compound is irradiated by a high-energy ultraviolet light beam. The oxidation reaction of the catalyst and the oxidation reaction of the positive oxygen ions are converted into low molecular compounds such as CO2 and H2O.
