Dust Filter PC 140mm for Computer Cooler/PSU/Routers Nylon 80 Mesh, Magnetic Frame Fan Dust Mesh PC Cooler Filter Dustproof Computer Fan Grills (Nylon, 140 * 140mm, 2pcs, Black)

These are exactly what I was looking for when I installed an additional rear chassis fan. The case has built in filters everywhere else, so in order to prevent dust from entering the case, I was looking for a filter that would be easy to use, ideally magnetic. This one works perfectly and can easily attach to the outside of the case without messing with screws or anything else for attachment. It does come with screws though if you want extra security.

useful, good quality nice one! Perfect size for OCD (finally refitted as expected). compare with other manufacturers, nylon is indeed much stronger in density, and the dustproof effect should be good there are cat hairs all over the house, I hope I can help to resist. the magnetic installation is very convenient, and I will repurchase it in the future. I plan to use it in my home NAS (Synology), PSP and other electronic products with heat dissipation,finally I found that my ITX needs it more : - )

It works well to add filters in locations that my PC did not have filters at a reasonable cost.

The frame is not firm, it is a soft magnet frame. The mesh itself is ok, but if you want to put it directly to the fan - it can be tricky.

Used on Fractal R5 case. Black color matched my case, you can't tell that it was an add on unless you really inspect it. Very easy to install, the holes lined up perfectly with holes on the case. My PC hasn't had any cooling issues after install. It doesn't seem to block much airflow into the case. You can feel the air still being pulled inside.

I really like just how fine the mesh is on these things as it helps gather even the tiniest bit of dust. I would give it 5 stars but it's just barely too big if you screw it down over the fans, causing it to have a little hump in the middle. I use the regular black Lian Li A3 case which doesn't have any front intake fans so I use one of the top mounted fans as an intake and I just sat this filter on top of it and it works perfectly, but that's because I didn't need to screw it in. When I tried to line up the screw holes with the screws in the fan that's when I noticed the filter was just barely too big and had a hump in the middle. If it was millimeter or two smaller I'd give it 5 stars and depending on how you're going to use this thing it could be perfect or it might not fit right. In my case the installation was extremely simple as all I had to do was just lay it on top of the fan. No noticeable difference in noise or cooling. In one of my attached pictures you can see how well it did when I was blowing a bunch of dust from around the ceiling in my office, the case fan ended up picking up some of it and it just stayed on the filter

I like that the frame of this filter is flexible and magnetized. It sticks perfectly to outer surface of my desktop without having to use screws. Filtering nylon is very dense, but not restrict air flow too much. It's washable.

These are great. That catch a lot of cat hair

Very Professional

I was looking for a 140x420, but I can't find one, so I opted to purchase a 140x140 pack, along with a 140x280 pack. 140x140 pack: Only 1 face is magnetized, and the magnet force is too weak, so it keeps falling off. I could use screws (size 140x140 has screw holes), but this defeats the purpose of getting magnetic filters for easy removal and cleaning. 140x280 pack: Again, the magnet is too weak, and only 1 face is magnetized. Also, due to the width of the magnetic strip, any screws from fans/radiators will prevent the magnet strip from fully mating with a case. This results in gaps, and then the filter falling off with the slightest vibration. Given the issues with both sizes, I cannot recommend any of the sizes in this listing.

Produit globalement correct, mais les vis noires livrées avec un article blanc… sérieusement ? C’était si compliqué de mettre des vis métal assorties ? Le détail qui gâche tout. Dommage.

Good quality overall. Easy to install. I suggest that this product be paired with reverse bladed fans, because if it gets installed at the front side where the blades are exposed, they can touch the nylon net during operation, which causes a small but annoying noise. I ended up removing the filter from the front and installing it at the back side of the fans, where the blades can't touch the net. This means that in my particular setup, the filter sits behind the intake fans, and dust filtration is possibly less effective due to this. If my fans were reverse bladed, I would have been able to turn them around, and then the filter would have been pinned on the "front" (next to the case side panel), leading to better dust filtration. Take this into consideration when buying fans. Not a big issue at all, but in my opinion still worth considering.

habe diese Staubfilter gut montieren können da die schrauben dabei waren
