The development of a gas clean technology may be one of the most expecting techniques in a wide field from global environment to living conditions. In this paper, the authors proposed the new concept of a gas clean technology by utilizing negative air ions and ozone gas with the formation of mist. A system is composed of the heat exchanger of staggered fins and a electrostatic precipitator. The negative air ions and ozone gas generated by corona discharge provide an electric charge and bactericidal effects. Formation of the mist in the field of super-saturation state by cooling of the system can make them high efficiency. Experimental data showed that the present system allowed air to be sanitized in high efficiency.
