PURPOSE:To obtain the title apparatus enhanced in ozone decomposing efficiency by providing an ozone removing filter, a shilelding means having an opening part exposing a part of said filter and the means moving the filter and the shielding means, and providing a use part and an unused part to the filter. CONSTITUTION:For example, a circular ozone filter 51 contains ozone decomposing activated carbon and an ozone decomposing metal type catalyst such as manganese and further has vent holes. An opening part 52a is formed to a part of a filter case 52 and the passage of the ozone filter 51 is constituted by this opening part 52a. The other part of the case 52 is composed of a shielding member preventing the invation of ozone into the filter 51. Further, the filter 51 is rotated so as to alter the exposed part in the opening part 52 of the case 52. By exposing the other shielded part of the filter to use the same when ozone decomposing efficiency is lowered, an ozone removing apparatus highly kept in ozone decomposing efficiency can be obtained. |
