PURPOSE:To obtain the titled apparatus high in the adsorption force for the tobacco smoke or the like by providing a fiber filter before a suction fan so that it can be endlessly rotated and also providing a vessel supplying water. CONSTITUTION:A net filter 1, a fiber filter 2 and an activated carbon filter 3 are provided in series from a suction port 8. The fiber filter 2 is constituted so that it is fitted to an upper and lower parts in a loop-shape via rollers 6 and can be endlessly rotated. Also a water storage vessel 7 for supplying water is provided to the under part of the fiber filter 2. While the air sucked through the suction port 8 is passed through the net filter 1, dust is removed and the fine dust incorporated in the air can be adsorbed by the following fiber filter. After adsorbing the odor incorporated in the air with the activated carbon filter 3, it is blown off through a blow-off port 9 with a fan 4. |
