PROBLEM TO BE SOLVED: To lean air according to the contamination condition of the air. SOLUTION: In an air supply path extending from an intake port 2 of a main body case 1 to an air outlet, provided are a blower 10 sucking the indoor air from the intake port 2 and blowing out it from the air outlet to the indoor, a deodorization filter 18 disposed serially to a dust collection filter 12 with respect to the flowing direction of the air supply path, a deodorizing bypass path 23 communicating with the upstream side and the downstream side of the deodorization filter 18 and being disposed parallel to the deodorization filter 18 with respect to the flowing direction of the air supply path, and a damper 24 opening/closing the deodorizing bypass path 23. The air cleaner switches a simultaneous operation in which the deodorizing bypass path 23 is blocked and dust collection and deodorization are executed at the dust collection filter 12 and the deodorization filter 18 and a dust collection operation in which the deodorizing bypass path 23 is opened and dust collection is executed mainly at the dust collection filter 12. Thus, other than executing the operation in which the conventional dust collection and deodorization are executed, the dust collection operation in which dust collection is mainly required can be executed. |
