<p>An air cleaner is provided with a front housing, a rear housing and a filter. The filter has a plurality of folding lines, which extend parallel to each other and partition a pre-filtering chamber and a post-filtering chamber. The air cleaner filters air by communicating air flowed into the pre-filtering chamber from an inlet port to the post-filtering chamber through the filter. The pre-filtering chamber has a diffusion space positioned outside the end portion of the filter in the holding direction. The inlet port extends in a direction vertical to the holding direction of the filter within a plane parallel to the filtering surface of the filter, and opens to the diffusion space.</p> |
