<p>A cleaning apparatus provided with a mechanism for circulation of an air, of which humidity is controlled, characterized by a filter provided with zeolite and having a permeability, and a particle removing filter provided downstream of the filter for removing particulate impurities, the both filters being disposed in an air circulation path. The cleaning apparatus can remove gaseous organic impurities contained in an air circulating therein without decreasing a humidity of the air. Since the cleaning apparatus does not make use of activated charcoal which is combustible, it is excellent in disaster prevention, and enables arranging of the filter and the particle removing filter in a roof section of the cleaning apparatus.</p> |
