PROBLEM TO BE SOLVED: To provide an air cleaner capable of suppressing the reduction in deodorization performance even when a high-molecular weight organic gas component is mixed in the use environment.SOLUTION: The air cleaner includes: a main body case having a suction inlet and an air outlet having opening directed outward, with a ventilation channel extending from the suction inlet to the air outlet a deodorization part disposed in the ventilation channel a filter for capturing dust, disposed more adjacent to the suction inlet than the deodorization part in the ventilation channel and a pre-filter disposed more adjacent to the suction inlet than the filter in the ventilation channel, which captures dust with larger grains compared with the dust captured with the filter and adsorbs an organic gas component with a molecular weight larger than the molecular weight of the odorous components adsorbed to the deodorization part.
