Dustproof 120mm fan filter

The dustproof guard fits 120mm case fans and blocks dust before it reaches internal components. It mounts directly over the fan frame using standard screw holes. The fine mesh reduces particle intake while allowing air to pass through.

Practical limits of the mesh

The filter adds slight airflow resistance that can lower static pressure at high fan speeds. Fine dust may still accumulate on the mesh surface over time and requires periodic cleaning. It does not stop liquid or conductive debris from entering the case.
