Multi-functional filter for removing contaminants from an enclosure

This invention describes a specialized filter designed to keep the inside of a computer disk drive clean. It's a single unit that sticks over an air vent, using an adhesive layer and at least two different filter materials to catch tiny particles and other airborne contaminants. The claims specifically focus on this filter's use in disk drives.

Why it matters: Since 2000, advancements in nanomaterials and polymer science have enabled more efficient and compact electret and adsorbent filter media. This could allow for superior multi-functional filters to protect modern high-density data storage devices, where contamination tolerance has become even more critical.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom filter materials, cleanroom assembly.
