An air cleaner includes a cylindrical cleaning filter, and a case rotatably receiving the cleaning filter therein. A dust-removing brush is disposed to contact with a filter portion of the cleaning filter, and a manipulating device coupled to the cleaning filter and accessible from outside the case enables the cleaning filter to be rotated from outside of the case.
