DIY 400×300 mm magnetic dust filter

This 400 mm by 300 mm PVC mesh filter is sold as a two-pack with eight 400 mm magnetic strips. The 1 mm holes block dust and hair while allowing air to pass. Builders can trim the sheet to fit any case intake or exhaust opening and attach it to a steel chassis without tools.

Suited for steel-chassis PCs and consoles

The magnetic frame works only on ferrous metal surfaces, so aluminium or plastic panels will not hold the filter. Buyers who need a filter for non-magnetic enclosures or who require a finer mesh than 1 mm should look elsewhere. The washable PVC material supports repeated cleaning for long-term use.

Sustained airflow with minimal restriction

Under continuous fan operation the 1 mm aperture maintains steady ventilation while trapping particulates. The mesh does not clog quickly, so static pressure and component temperatures remain stable over extended sessions. Magnetic strips keep the seal intact even when the case vibrates during heavy loads.

Questions about this item

Does the 400 x 300 mm mesh fit the intake opening on my case?

Measure the opening first; the sheet is 400 mm by 300 mm and can be trimmed with scissors to match any smaller rectangle.

Will the magnetic strips hold the filter on a steel case panel?

Yes, the eight 400 mm strips use 3M adhesive on one side and strong magnets on the other, so they bond to ferrous metal without drilling.

How can I confirm airflow is not restricted after fitting the filter?

The 1 mm holes are designed to pass air freely; check that intake temperatures stay similar to before installation.
