There is provided a disk drive including a disk drive base, a disk rotatably coupled to the disk drive base, and a spindle motor attached to the disk drive base and configured to support the disk for rotating the disk with respect to the disk drive base. The disk drive further includes a filter component. The filter component includes a filter housing coupled to the disk drive base, and a pair of filter elements disposed within the filter housing for filtering disk rotation induced airflow. Each filter element includes a coarse section and a fine section, wherein the coarse section is positioned upstream of the fine section relative to a direction of the induced airflow.

We claim: 1. A disk drive comprising: a disk drive base; a disk rotatably coupled to the disk drive base; and a filter component including: a filter housing positioned in a cavity of the disk drive base, wherein the filter housing comprises first and second, spaced apart openings; and a pair of filter elements disposed within the filter housing for filtering disk rotation induced airflow, one of the pair of filter elements is exposed to the first opening and the other of the pair of filter elements is exposed to the second opening in the filter housing and each of the filter elements comprising a coarse section and a fine section, wherein for each of the filter elements the coarse section is positioned upstream of the fine section relative to a direction of the induced airflow. 2. The disk drive of claim 1, wherein the filter elements are spaced apart in the housing and wherein at least a portion of the induced airflow flows through the coarse sections into the filter housing and then out of the filter housing through the fine sections. 3. The disk drive of claim 1, further comprising: a head stack assembly, the filter housing disposed upstream of the head stack assembly with regard to the induced airflow; and a second filter component including a filter housing positioned between the upper facing side of the disk and a cover of the disk drive and a second filter element disposed within the filter housing for filtering a portion of the induced airflow flowing along the upper facing side of the disk. 4. The disk drive of claim 3, further comprising a third filter component that includes: a filter housing positioned in another cavity of the disk drive base proximate to an edge of the disk, the filter housing comprising only one opening and the one opening is positioned adjacent to the edge of the disk; and a third filter element disposed within the filter housing for filtering the induced airflow, the third filter element including a coarse section and a fine section both exposed to the one opening with the coarse section being disposed upstream to the fine section with regard to the induced airflow.
