A disk drive includes a disk drive base, a rotating spindle attached to the disk drive base, and a disk mounted on the rotating spindle. A disk drive cover is attached to the disk drive base to enclose the disk in a disk drive enclosure. A filter within the disk drive enclosure includes first and second nanoporous adsorbent materials, each being either a metal organic framework material or a covalent organic framework material. The first nanoporous adsorbent material is fluorinated, and the second nanoporous adsorbent material is not fluorinated.
1. A disk drive comprising: a disk drive base;a rotating spindle attached to the disk drive base;a disk mounted on the rotating spindle;a disk drive cover attached to the disk drive base to enclose the disk in a disk drive enclosure; anda filter within the disk drive enclosure, the filter including
1. A disk drive comprising: a disk drive base;a rotating spindle attached to the disk drive base;a disk mounted on the rotating spindle;a disk drive cover attached to the disk drive base to enclose the disk in a disk drive enclosure; anda filter within the disk drive enclosure, the filter including first and second nanoporous adsorbent materials, each selected from the group consisting of metal organic framework materials and covalent organic framework materials, wherein the first nanoporous adsorbent material is fluorinated and the second nanoporous adsorbent material is not fluorinated. 2. The disk drive of claim 1 wherein the filter is a recirculation filter. 3. The disk drive of claim 2 wherein the recirculation filter is impregnated with the first and second nanoporous adsorbent materials. 4. The disk drive of claim 1 wherein the filter is a breather filter. 5. The disk drive of claim 4 wherein the breather filter includes a first container that includes the first nanoporous adsorbent material and a second container that includes the second nanoporous adsorbent material. 6. The disk drive of claim 4 wherein the breather filter includes a first container that includes first granules of the first nanoporous adsorbent material and second granules of the second nanoporous adsorbent material. 7. The disk drive of claim 6 wherein the breather filter further includes a second container that includes a desiccant material. 8. The disk drive of claim 1 wherein the first nanoporous adsorbent material is a metal organic framework adsorbent material that includes an organic linker and a metal selected from the group consisting of Zn, Cu, Mn, Cr, Fe, Al, and Ni. 9.
