Dust Filter PC 120mm for Computer Cooler Fan/PSU/Routers Nylon 80 Mesh, Magnetic Frame PC Fan Dust Mesh PC Cooler Filter Dustproof Computer Fan Grills (Nylon, 120 * 120mm, 2pcs, White)

For keeping the interior of your computer tower cleaner, these filters are phenomenal. They magnetically attach to your computer case (unless it isn't metal) and, because the mesh is msaller than the most on most computer grills, they act to prevent more dust and particles from getting inside W/Out impeding airflow!For my top grill, I placed a computer fan on this filter, pushing cool air into the computer case w/out added debris getting inside (because of the filter).I am extremely happy with these and would recommend with the highest confidence!Hope this helps!

useful, good qualitynice 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 goodthere 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 : - )

There are to peices to the frame, a magnet and a plastic side. Over time these sides begin to separate from eachother. This can be an easy fix but it's definitely worth mentioning. Other than that it filters well!

The product is great! Very fine mesh as described, blocks most of the dust, the filter has just enough holes to catch dust particles without making the air flow too bad. After about a week of use, you can see that there is quite a bit of dust on the filter, at which point you can remove the dust filter PC and wash it with water, and it will continue to work like new! Or use a vacuum cleaner to carefully clean up the dust!For anyone who puts their PC case on the floor, I definitely recommend buying it!

Having dogs, the pet hair is easy to filter out, but the fine dander dust is difficult. These are a must for those who are serious about keeping the machine clean. The fine filter does restrict air flow, but at least you are getting CLEAN air.

Really inexpensive considering I recall having purchased filters nearly identical to these from a premium brand at a premium price.Airflow naturally gets restricted a little when you install these on a PC, but I dremeled out the fan hole's steel mesh on my PC case to unrestrict a little airflow, so...? I suppose it cancels out.You may find that one or two of the sides of these won't lay flat on your PC case. At least for me, this was my experience when placing it on the bottom fan (where my case is made of aluminum and not steel). It's not impossible to get it to lay flat, you just will have to loosen all four of your fan screws a little, then either play finger twister with your hand to hold it down while tightening the screws, OR use tape to aid installation. Experiment with tightening screws round robin, or perhaps tighten one corner then the opposite corner immediately after. There's a trick to it, and it's not too difficult to figure out. You'll see as you try. The key is just to get all screws 80% tightened so the filter has no tension dragging it anywhere when you start.As for the filter itself, it's premium nylon mesh. Doesn't get any better than this if that's what you're after.

This dust filter PC is not designed with neodymium magnets, which can protect the electronic components well. Its included screws can play a perfect role in reinforcement, and the attached stickers can also help me solve the problem of cellar dust. Filters well, I believe I will only clean it once a month.Perfect size, nice product. It covers the vents perfectly.

Had they of made the magnetic portion of the filter actually not extend into the air flow of the fan this would have been perfect. The magnetic portion is included in the 120mm measurement. The filter should be the measurement of the fans then the magnetic part surrounds that.

Recently moved a pc down to a rec room that has a wood stove in it on most weeks during winter and I was worried about the dust and ash factor(s). Grabbed these guys and haven’t had to worry much.The magnetism is rather strong but you can also screw them directly to fans with ease. Just remember that you will need to clean them periodically so choose the easiest method for removal.

Sehr günstig und hochwertig gearbeitet

Okay so I have returned these but that's not because they are bad, they just made the argb fans in my rig look square. Upon inspection they seemed quite good, came with all the extra screws needed and had very fine filters and didn't really restrict the flow much. Unfortunately though they just made my fan lights look wrong as they cover the sides of the fan by about 3 or 4 mm making the fan lighting effect look square. If the argb is not a concern for you then I'd suggest getting them.

I like how thick the borders are and how tight the mesh is. It should block a lot of small particles.

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.
