Abstract: An air cleaner has an electric precipitating apparatus that employs corona discharge and an ozone removing apparatus downstream of the precipitating apparatus. The ozone removing apparatus has a carbon filter, and is charged with a low positive voltage to remove ozone generated by the precipitating apparatus by chemical conversion to oxygen and carbon dioxide.
Abstract: An air cleaner and an air filter for removing charged ozone in the air includes an air filter having a carbon filter for adsorbing charged ozone in an air path of the air cleaner and converting ozone adsorbed in the carbon filter to oxygen and carbon dioxide by a chemical reaction. A positive voltage is applied to the carbon filter.
