A generally flat air filtering device for an optical disk drive is disclosed. As air is sucked into the disk drive via an inlet of a filter, a filter mat included in the filter removes dust and other impurities from the air. The purified air comes out of the outlet of a tube and then enters and cools an optical disk unit. The filter mat has a generally V-shaped section and, therefore, has a filtering area great enough to enhance efficient dust collection as well as the service life of the filter. To isolate the purified air from surrounding dust-containing air, an endless projection or rail is provided on the tube to bite into the filter mat which is flexible.
