PURPOSE:To effectively purify gas against the contamination due to harmful gas by bringing the gas into contact with ozone generated from a ozonizer and bringing it into contact with a composite oxide catalyst having ozon resolution and harmful material adsorptivity. CONSTITUTION:A collecting decomposition part 6 of an air purifier 4 is constituted of an ozonizer 11 and a composite oxide catalyst 12 and tobacco odor components, etc., are removed here. The ozonizer 11 is of discharge type, etc., and a honeycomb manganese dioxide catalyst, etc., are used as the composite oxide catalyst 12. A fan is installed in a fan part 7 and sucks air to be treated 8 and discharges the treated purified air 10. Consequently gaseous harmful components are effectively treated by ozone and the composite oxide catalyst. And tobacco odor is removed by ozone. |
