Pros & Cons

Pros

  • ✓ Four 400x300mm PVC sheets cut to any vent size, no pre-cut sizing to match
  • ✓ 16 x 400mm magnetic strips included, enough framing for several filter panels
  • ✓ 1mm mesh apertures block dust and pet hair without choking intake airflow
  • ✓ 3M adhesive backing means no drilling or screws into the chassis

Cons

  • ✗ Magnetic mounting needs a steel panel; won't stick to aluminum or tempered glass
  • ✗ Requires measuring and cutting yourself, unlike drop-in pre-sized filters
  • ✗ PVC mesh is less rigid than aluminum-framed filters over large spans
  • ✗ 3M adhesive is one-shot; a misaligned strip is hard to reposition cleanly

Manufacturer description

The MoKo 400x300mm DIY PC case dust filter kit solves the problem most magnetic filters create: fixed sizes that never match your chassis. You get four 400x300mm PVC mesh sheets you cut to your own measurements, plus sixteen 400mm magnetic frame strips with 3M adhesive backing, so you build a filter around any intake, exhaust, or PSU vent instead of hunting for a pre-cut match. The 1mm mesh apertures block dust and pet hair while leaving airflow largely unrestricted, which matters if you are filtering a front intake feeding a GPU. Installation needs no drilling and no screws: peel the…

Frequently Asked Questions

How many filters do you actually get for the price?

The package includes 4 sheets of 400x300mm PVC magnetic mesh plus 16 magnetic strips of 400mm each, priced around 15.99 dollars.

Will these stick to my case if it has a glass or aluminum side panel?

The magnetic strips attach to iron and steel surfaces. On aluminum or tempered glass panels the magnets will not hold, so plan to mount on a steel intake shroud or fan bracket instead.

Do I have to cut the mesh myself?

Yes. Measure your case's cooling port, cut the 400x300mm sheet to size, then attach the 3M-backed magnetic strip around the edge. No drilling is required.

Does the filter restrict airflow enough to raise my temps?

MoKo specifies 1mm holes, sized to trap dust and hair while still passing air. Any filter adds some restriction, so clean it regularly to keep intake flow consistent.

Can I use this on anything besides a PC case?

The PVC mesh is listed for speaker grilles, other electronics, and gaming console vents including Xbox Series consoles, in addition to PC chassis and fan intakes.
