Adsorbent breather filter

This device is a filter for keeping sensitive electronics, such as disk drives, clean by removing airborne particles and chemical vapors. It's an assembly that attaches to an enclosure's air port, using an adhesive layer to secure a hydrophobic porous polymeric membrane that traps contaminants, while a separate porous layer allows air to pass through.

Why it matters: Since 2004, advancements in materials science have yielded more efficient hydrophobic membranes and advanced adsorbent media, enabling superior contaminant removal in smaller footprints. This allows for higher-performance, multi-functional filters crucial for the increasingly compact and sensitive electronic devices prevalent today.

Status: In forceA lapse was cured by a late fee and protection was reinstated.
How hard to build: ModerateHydrophobic membrane, adsorbent media, precise layering.
