BGears Fan Filter 120mm case accessory, 2-pack

120 mm Dual-Pack Fan Filters

This two-piece set of 120 mm fan filters mounts directly onto case fans to block dust from entering the chassis. Each filter uses a black plastic frame with a washable foam element that can be removed for cleaning. The 10 mm thick assembly adds minimal depth inside the case. Fans and mounting screws are not included.

Check Fan Mounting Points First

Verify that your case has 120 mm fan locations with standard screw spacing so the filter frame can sit flush against the fan. Ensure there is enough clearance behind the fan for the extra 10 mm thickness added by the filter housing. Confirm you have four mounting screws per filter, as none are supplied in the pack.

Ideal for Dust-Prone Builds, Not for Radiator Users

These filters suit builders who want to reduce dust on components in air-cooled systems with 120 mm intake or exhaust fans. They are not designed for liquid-cooling radiators or for fans with non-standard frame shapes. Buyers needing magnetic attachment or finer mesh for high-static-pressure setups should consider other solutions.
