PROBLEM TO BE SOLVED: To use only one device in air purification and fumigation using ozone, without changing flow passages. SOLUTION: This device has a flow passage 4, in which almost the total amount of air sucked from an inlet 1 is passed through a first ozone generator 5, an ozone decomposser 6, and a second ozone generator 7 in sequence and then emitted from an outlet 2, and the device selectively operates the first and second ozone generators 5, 7 to perform deodorizing and sterilizing action, when contaminated air sucked into the device is decomposed by generating ozone, and fumigating action by releasing the ozone generated in the device out of the device. |
