DIY PC case dust filter

This magnetic mesh filter measures 1000 x 300 mm and fits computer chassis, speaker cabinets or similar enclosures. The PVC frame carries a 0.03 inch hole pattern that blocks dust and hair while letting air pass. Four magnetic strips hold the sheet in place without screws or adhesive. Builders who need a custom shape or a different mounting method will not find those options here.

Thermals noise and power draw

The mesh does not restrict airflow, so intake and exhaust fans keep their normal thermal performance and acoustic profile. No power is required and the filter adds no electrical load to the system. Because the sheet is passive, it neither generates heat nor changes fan speed curves. Installers who expect active cooling or fan-speed control from the filter itself will not get it.

Bundled magnetic strips

Four magnetic stickers are included and attach directly to the filter frame for tool-free installation on ferrous surfaces. The strips simplify cleaning — lift the sheet, rinse or vacuum, then snap it back. No screws, brackets or adhesive tape are supplied. Cases with non-magnetic panels or irregular mounting points will need a different fastening solution.

Questions about this item

How do I attach the 1000 x 300 mm filter to my case, and what step is often missed?

Clean the mounting surface first, then press the four included magnetic strips onto the frame; the filter snaps to them. The step people skip is degreasing the metal so the adhesive on the strips actually holds.

What upkeep will this mesh need over time?

Vacuum or rinse the PVC mesh when dust builds up; the .03 inch holes trap fine particles but stay permeable. The magnetic strips stay in place, so you only clean the filter sheet itself.

At what point does airflow noticeably drop during heavy use?

Restriction rises once the .03 inch mesh pores clog with fine dust; a quick rinse restores full flow. The thin PVC material adds virtually no static pressure penalty when clean.
