287mm 140mm x 2 PC Fan Dust Mesh Filter 11.3inch x 5.79inch PVC Computer PC Case Dust Proof Filter Cover Magnetic Black 2-Pack

Excellent product! I purchased this to filter the back panel intake fans on my MuseTex K2. Packaging is super nice, filters are high quality, and installation is as easy as letting it snap on to your case. Airflow is not restricted, and the filter with help keep a ton of dust out :)

I got two, one for each PC in the living room where the cats spend the majority of their time. They fit the towers perfectly, were easy to put on with the magnets holding it firmly in place, allows airflow, and keeps out the cat hair!

I would be cautious using these for high flow in-take fans. This would probably work best for slower fan configurations as they mesh is very tight. The quality of them are quite nice though.

High quality, strong magnets, fair price. Only thing to note is that the mesh is very dense, so it might restrict air flow a little bit, but will obviously do a great job of filtering dust. I mostly just use them on the top of my case where there's spots for exhaust fans that I don't even have installed. If you're gonna use it for intake, might be worth seeing what your temperatures are like before and after.

My case has huge ventilation holes in the top with no filter or fans, so dust and anything smaller than 1/4" just falls right down and settles inside. This solves my problem perfectly. I'm sure some dust will make its way through, and it might limit air movement, but at least I don't have to worry about bugs or other large debris falling straight in and potentially damaging sensitive parts. Looks pretty good too.

So, obviously if you're considering buying this, you are concerned about what ends up on your computer's internal components. Sure you don't want dust, but you do want fresh cool air and plenty of it. This filter is very restrictive of air flow, and in my application with dual noctua 140mm fans as my inlet fans, this filter simply did not allow enough air flow. This led to excessive temperatures inside my rig, and a net negative air pressure with (and get this) a single stock exaust case fan at the rear of my case. Literally air was coming in through the open slats at the back of my pc. On the other hand, this is a well made filter and it does stop a certain dimension of contaminant from entering your rig. The magnets are well affixed and cut and the material (except for its restrictiveness) is very good. That's why it deserves 3 stars.

When my new desktop computer arrived with huge air openings over an 8 x 5 inch area of the tower, I was horrified. I couldn't believe they would sell a computer whose inner workings were so exposed. "Dust will take this out in no time," I thought to myself. It occurred to me to look for some kind of screening I could rig up and tape to the side. I had no idea this was such a universal problem these days, because there were so many dust screen products being sold for just this purpose. So I reviewed them for about an hour and decided on these. Perfect! Couldn't be easier to use! Three seconds, and the problem was solved! I am extremely happy and relieved. If the area you need to cover is within the measurement of this product and metal, I highly recommend.

Good quality, the holes are a good size, and the magnets are strong. Excellent for the price.

As someone who has had to go to great lengths to keep dusk out of their tower computers a simple and easy solution is always preferred and Having to install custom-fitted mesh screens that can be hard to clean after being installed. These magnetic covers can sit on the inside or outside of the case over the intake fans, they do not restrict the airflow very much and the magnets are strong enough for a good seal. I also cut and adjusted the magnet locations to get more surface area. These covers are large enough to cover most vents but I recommend you measure your vent locations before making the purcase.

Magnet strip came off of one of them but definitely catch alot of dust from my house

I was looking for a way to prevent cat hair from entering the inside of the case, and the holes on this filter are tiny enough to do that. Please note that this will obstruct airflow somewhat and give you slightly higher thermals. Most excess airflow will follow the path of least resistance, that is, toward the back of the case. For me, it's a small price to pay to keep the inside of your case clean.

A little too dense to give my PC good air circulation so that was a no go but it turned out to be the BEST way to keep leaves out of the cowl on my Jeep so there you go!

I have an alienware Aurora, and the case is plastic so they don't stick to it.
