ABSTRACT:
A filtering apparatus of a hard disk drive includes a filter filtering particles from air flowing inside a housing which includes a base plate and a cover plate, and two holders installed inside the housing and having support grooves supporting both end portions of the filter. The filter includes a filtering portion through which the flowing air passes and particles are filtered from the flowing air, and an insertion portion included at both end portions of the filtering portion and inserted into the support grooves forming a seal. Thus, since no gap is generated between the support groove of the holder and the insertion portion of the filter, all the air flowing toward the filter passes through the filtering portion. Also, the flow of air passing through the filtering portion is smooth, so that an efficiency of filtering tiny particles included in the air flowing in the hard disk drive is improved.
