400x300mm DIY PC Case Dust Mesh Filter, 2Pack PVC Dustproof Mesh Filter Cover with Magnetic Strip for Computer PC Case

I recently built a new PC for my son after his mini PC failed suddenly. I wanted to go with a full sized ATX build, as I usually make for myself, and picked a Lian Li Lancool 207 case. After building the system in the case, I realized that the air intake meshes were great for airflow but also great at letting dust in. I have previously made DIY magnetic filters for my Phanteks P500A case when the same situation faced me a few years back, so I looked at my options and selected this one largely on the basis of good price with a good review average. I am pleased to say it was a great choice. I had no trouble making intake filters for all of the meshes on this case. There's one particularly unprotected air intake which has very large hexagonal gaps the same size used for the rear air outflow, and I think covering that one is actually pretty important if you don't want a lot of dust coming in where SATA drives are, blowing right up into your video card through the horizontally mounted fans (you know what hates dust? horizontally mounted fans, really hard on their bearings over time as lubrication distribution is harder for them than vertically mounted fans). Please view the attached photos so you can see what I mean when I said there's plenty of materials to make all the filters you need for a case with modern airflow. Speaking of, they do reduce airflow somewhat compared to unimpeded bigger gaps, but if you're in a modern case you should still have very good airflow. I've used something exactly like this for years on my P500A case with a 12900K and it has never caused temperature issues, despite covering the entire front intake mesh so I reckon it's going to be a winner for keeping the interior clear of dust (which tends to help keep air moving nicely, you know?)

This is the stuff here, excellent thickness, plenty of material to fully filter an entire larger size gaming tower. It comes packaged in a large plastic sandwiched between two pieces of cardboard that keep it from getting beat up, folded, or otherwise damaged. No mesh will ever fully dust proof your computer, this will only increase the amount of time between routine cleanings that are necessary to keep your system running at peak performance. The holes are on this are such that they should be able to keep out pet hair, your hair, and larger material. I don't notice any restriction in air volume and temps seem relatively stable in very close to pre mesh temps, I'm seeing a .5 to 1 degree c increase which is negligible. This stuff is easy to work with, cut, and attach the magnets. Magnetic hold is pretty decent as well. After reading reviews on several others like this I noticed a common thing in that generally it's shipped in a roll which gets damaged in shipping. This was one of the few that is shipped correctly and the price is lower than others that are shipped rolled. Save yourself a few bucks and the aggravation of receiving damaged mesh and go with this one.

I only recently installed the mesh filter. I rebuilt my computer and the original dust was awful. The stock shapes (rectangle) would only have covered some of the vents. I was able to customize the mesh to fit all the vents. A straight edge ruler and pencil line made an easy job of marking the screen. Pencil lines show enough to cut the shapes with a sharp utility knife. Remember to cut the magnetic pieces to fit together to keep the dust out. Magnets work best directly on the metal case. Airflow seems unimpeded. 1 sheet covered all of my computer's vents. I may have to do a follow up review in a few months regarding the dust build up after installing the filters on my rebuild.

I am pretty pleased with this mesh. I wanted to go for a pre-sized on for my Meshify case, but couldn't find one with the right measurements. This requires cutting to size, but I should be able to get 4 perfectly sized screens out of this one pack. I also like that the magnets are wider than the originals, so you don't get the same shearingfrom pressure when cat sits on top. My biggest gripe is that the magnet adhesive isn't very good. I placed and then pressed between boards for a few hours and the bond didn't last but a few weeks. Over all I think it's a great replacement.

Worked really good. I used a paper cutter for screen and cut magnet tape with scissors. Looks very good after installed. I replaced dust filter kids messed up and made a filter for a computer that didn’t have a filter on top intake fan. I would buy this again when needed.

Works great, both the adhesive and magnetism are efficient in strength. I placed a magnet wrong and after two days I was able to peel it off and reapply it to a new spot with no sticky residue left behind and plenty of adhession to keep using the same magnet. Only using scissors, I managed to make some pretty clean cuts so it's pretty easy to use.

My new case curiously lacked a front intake fan filter and after failing to find a filter by the case manufacturer, I turned to the DIY route. The package arrived fast like always, and within 15 minutes of receiving the product I had a very impressive custom fit magnetic filter. Time will tell if the adhesive fails in the future, but should it, glue will remedy that pretty quickly.

Perfect. Broke glass, now it's dust screen heat releasing class. Cheap. Cuts easy. Use a new utility blade.
