120mm PC Case Fan Magnetic Dust Filter Screen, Black Color, 4 Pack | Dustproof Case Cover with Magnet, Ultra Fine PVC Mesh

Bought these to try them out and now I cant see me without using them for now on. I have several dogs and where my PC sits isnt the greatest, so I was cleaning it out every month or so. Now? its every 3 to 4 months. Only the smallest of dust particulates get through and should they get caught by the exhaust fans another set of micro-mesh filters catches it that came with the case. Worth every penny

No issues. Strong and firm. Replaced the 7 year old magnetic screen that was literally falling apart. Nice to start fresh. No screw holes in these ones so can't be used with a fan, but for my application they work fine. These also look like they're higher quality mesh than my last one too.

They worked fine for our application, which was a reversed fan at the rear of a full size computer case...plenty of flat metal for the screen to adhere to. The magnets are plenty strong enough and stay in place. I even cut one screen in half to cover an open area (also at the rear) because I mounted the video card vertically and that left a slot area wide open...I didn’t want any dust to get in the case. With only three sides, the magnets of the screen held in place. To clean, all I used was the brush attachment of my vacuum cleaner. If you have plenty of flat area around where you want it to go, these filters are perfect.

they work great as dust covers for 120 mm fan holes i cut in my side panel. protects the fans also and keeps your case cleaner

Quality dust filters, easy to install and remove and seem to need a light rinse to clean off.

I purchased these because I moved my computer onto a carpet and it got noticeably more dusty. I've since removed the carpet but I've kept these. i think these are really awesome for the price. They definitely keep at least some dust out- it collects on the filter (so i just wipe it off). They blend in with my black case really well. I don't know if they impact thermals at all, my case is very well ventilated- I probably had some air to spare. No increase in temperatures so far. Build quality is good. They're light weight but they aren't a structural piece so i don't see how it would be possible to break them. I'm happy with these 04/2026 UPDATE: After 1 year of ownership, I can say that these are still ok for capturing dust, but I am downgrading to 3 stars. The adhesive that holds the magnets onto the screen is very weak. I treat these very carefully and try to remove them infrequently for cleaning, but the magnets are still coming up. Yes, I can and will glue these back myself probably, but I feel as though I should not have to.

used on my pc as a dust cover for the power supply and used it on my sons pc for the gpu works very well with enough strength to not worry about it falling off

Not much to say. It's a mesh and it has a magnet. I have cut these in half for smaller vents and it has held
