120 mm Fan Dust Filter Pair

This two-piece set fits standard 120 mm square case fans and blocks dust before it reaches internal components. It is aimed at PC builders and maintainers who want cleaner airflow without dismantling their cooling setup.

High-Flow Mesh Thermals

The precision micro-mesh structure lets air pass freely while trapping particles, so intake temperatures stay close to an unfiltered fan. The thin 0.35 in plastic frame adds negligible resistance and produces no audible noise of its own.

Tool-Free Case Integration

Each filter snaps onto a 120 mm fan frame without screws or clips, working in desktops, workstations and servers that use square 120 mm mounts. The 4.92 in square footprint matches the fan exactly, leaving surrounding brackets and cable routing untouched.

Questions about this item

How do I install the 120mm fan filter without tools and what step is often missed?

Align the filter's 4.92 in square frame with the fan mounting holes, press the plastic clips through each corner, and ensure the .35 in thick mesh sits flush against the fan frame so no gaps remain.

What maintenance will the plastic mesh filter need over time?

Remove the filter every few months, rinse the plastic mesh under lukewarm water, shake off excess moisture, let it dry completely, then snap it back onto the 120mm fan.

What limit appears first when the filter runs continuously in a dusty environment?

The fine plastic mesh gradually loads with particles, increasing airflow resistance until cooling performance drops and the filter must be cleaned.
