<p>PROBLEM TO BE SOLVED: To carry out the perfect air cleaning inexpensively without necessity of forming a large setting space. SOLUTION: An air filter 10 and an adsorption sheet 15 are provided in a casing 1 formed into the oval container shape. A fan unit 40 is set in an inner space of the adsorption sheet 15 for the suction of air, and suspended matters are removed by the air filter 10, and odorous matters and the like are removed by the adsorption sheet 15 respectively to prepare clean air. On the other hand, a shutter 21 provided between the air filter 10 and the adsorption sheet 15 is closed, and then the adsorption sheet 15 is heated and regenerated, and the odorous matters and the like separated from the adsorption sheet 15 are decomposed by a catalyst heater 30.</p> |
