Four-pack 120 mm fan filters for dust protection

These four black square filters measure 120 mm on each side and mount over standard case fans. The ABS resin and nylon fibre mesh stops roughly 90 % of dust while maintaining airflow. They suit desktop PCs, gaming rigs and server chassis that use 120 mm fan mounts.

Mesh design balances airflow

The fine mesh carries an IP40 protection level and a quoted 90 % dustproof rate, so it blocks most particulates without choking the fan. Mounting holes sit on a 106 mm pitch and the frame is 10 mm thick, adding minimal depth inside the case. Screws are not supplied, so existing fan screws must be reused.

Replaces loose grilles

Builders who currently run open fan vents or damaged screens gain a quick, tool-free upgrade that clips onto the fan frame. The pack covers four positions, enough for a typical front or top intake array. It does not address radiators, non-standard hole patterns or fans larger than 120 mm.

Questions about this item

Which pack size should I pick for a standard mid-tower build?

The product is sold as a 4-piece set of 120 mm square filters, covering the typical front and rear fan locations on most mid-tower cases.

What does the 90 % dustproof rate mean for everyday use?

It blocks roughly nine out of ten dust particles while the mesh still lets air pass, so internal components stay cleaner without choking airflow.

How does the IP40 rating affect what the filter stops?

IP40 means it stops solid objects larger than 1 mm — such as dust fibres and pet hair — but offers no protection against liquids.
