Woanger 2 Pcs 1000 x 300 mm DIY PC Case Dust Filter PC Fan Mesh Filter Floor Vent Cover PVC Dustproof Cover with Magnetic Strip for Computer Chassis Speaker and More, 0.03 Inch Hole, Black

I like being able to cut it to the size I need but it needs more magnetic tape.

I bought the two pack which came with just enough PVC mesh to cover all of the vents on the NZXT H7 Flow (2024). That case is a bit on the larger side so I was happy that I was able to create my own filters that fit perfectly. It takes a bit of time to get the measurements of your case but it’s worth it. It does impact airflow but not by a large amount. For me, preventing cat hair and dust from collecting inside my pc is far more worth it than losing a few degrees. This can be offset by slightly increasing fan rpm’s if you find that not enough air is coming through. My only issue is that the mesh came with some dents that are unlikely to flatten out. This is more so a problem with the way it was packaged rather than the quality of the mesh itself (only visual flaws). All in all I’m satisfied with this product and I highly recommend using this if your PC case does not come with dust filters already.

Honestamente pensé que las micro perforaciones iban a ser mas grandes, pero resultaron ser mucho mejor, son mas pequeños haciendo que filtre solo el aire...sinceramente fue la mejor compra...

Hope this works. My apartment has strange grey, black dust, turns into hard black tar and destroys computer electronics. Small holes in these screens seem good. Hope it doesn't interfere with cooling, airflow. I can breathe on it and feel the breath exit on the other side, so these might be good! I will not use the magnetic strips, included separately; not sure if magnets will erase, interfere with the electronics in the computer, like they can with magnetic strips... on a credit card. I do not know if the filter can block tiny dust, dirt but it looks like it might work.. Good price. UPDATE: it works but the strange black dust inour building still gets into my computers, but less. GOTTA MOVE!!

Made a front and top filter for my Rosewill Thor NAS case. And have plenty of mesh and a bit of magnet left. Arrange the magnets with sticky side up, slap the mesh on, cut the edges with a razor. Docked a star for the magnets being bent, was able to work around that part but still an annoyance.

I have used this on several PC's in order to cover and replace all the dust filters that I need. The package comes with magnetic strips that are very useful in many of the replacements.

I thought to myself how bad could it be. Well. The magnets came bent and mostly unusable. They are nowhere near strong enough to overcome the bends in them, and they dont reshape very well even when trying to bend them back straight. Screen will have dents/damage on it as well. If you care about looks and functionality. Look elsewhere.
