360mm 120mm x 2 PC Fan Dust Mesh Filter 4.72inch PVC Computer PC Case Dust Proof Filter Cover Magnetic Black 2-Pack

Better quality than the photos show.

Actually came well packed in a box and they had a hunk of foam between the vents so they were nice and flat, nice fine mesh that should for sure stop dog fur, most dust etc. the magnets were glued on nice with no issues. Not overly strong force but they hold OK. So all in all for the price a good stick on filter.

I work in a very dusty warehouse. Our old stereo died from what I'm guessing was a decade of dust and neglect. I bought a new component receiver and it had all these giant hole vents on top, so I bought this to cover the openings and so far it has worked like a charm! I even bought a few more to cover the side venting too.

The magnets easily hold the screen when used upside down on the bottom of the Lian Li PC-O11DX 011 DYNAMIC ATX Mid Tower Gaming Computer Case Black. I had lost the original screen that came with the case and this is a great replacement. I was concerned by others reviews that the magnets were not that strong. However the magnets will hold the screen when used upside down. If used on a case where fans are blowing directly at it without anything else on the other side, I can see that maybe the screen won't hold. However when used as a screen where the fans draw air in from the other side, this will work fine. This will also work on cases where there is something else on the other side of the screen such as the Lian Li PC-O11DX 011 DYNAMIC because the screen fits between the case and the top panel or side panel. The holes are small but air does pass through. I am only using this screen in a pull from outside of case configuration where the screen is on the bottom of the case held by the magnets just like the original screen would have been there.

The filters work well. Ive noticed that there's no dust on my hard drives when I clean the computer case.
