Ruth's sister 120mm Black PVC Fan Dust Filter 5 Pack internal power cable

Five cut-to-size PVC filters

A pack of five black PVC mesh filters each measuring 120 mm by 120 mm. The material can be trimmed with scissors to fit smaller fan mounts or irregular openings. They sit at the fan inlet to catch dust before it reaches the blades and internal components. Supplied as a five-piece set for multiple intake points.

Builders who want simple intake protection

Suits anyone assembling or upgrading a case who needs a low-cost way to reduce dust build-up on fans and heatsinks. The PVC mesh is flexible enough to conform to slightly curved grilles. Buyers who need magnetic mounting frames or fine-pore filtration for clean-room environments should look at something else.

Steady airflow with minimal restriction

Under continuous operation the open mesh structure lets air pass freely while trapping larger particulates. The PVC does not degrade noticeably from the warm exhaust air typical of case interiors. Cleaning is a matter of rinsing or vacuuming the filters periodically to maintain the original airflow rate.
