ABSTRACT:
An air cleaner eliminates moisture laden in air, thus preventing the moisture from being added to a dust collecting filter and, for example, a deodorizing filter, therefore preventing performance of the dust collecting filter and the deodorizing filter from being deteriorated. The air cleaner includes a cabinet having an air inlet port and an air outlet port, a blowing unit provided in the cabinet to circulate air from the air inlet port to the air outlet port, and a filtering unit provided between the air inlet port and the air outlet port to filter the air drawn into the cabinet. The filtering unit includes a dehumidifying filter to adsorb moisture laden in the air, a dust collecting filter to collect dust laden in the air, and a deodorizing filter to remove an odor from the air. In this case, the dehumidifying filter is placed nearer to the air inlet port in comparison with both the dust collecting filter and the deodorizing filter.
