140mm x 2 Fan Mesh Filter PVC Computer Case Dust Proof Cover Magnetic White | Magnetic PVC Dust Filter 11.3x5.79 Inch for Computer Fans, Speakers, Electronics - Reduces Cleaning, Prolongs Component Life

I give these dust mesh filters the top score because the are well put together and the material of the PVC does not feel flimsy. The rounded corners is a plus in my book, very easy to install and reuse, be careful because the adhesive on the magnets is not designed to yank the filters on and off, as with any dust filters for computers, be gentle. It is a small investment to reduce dust contamination inside your PC case, it is a good value for your money. Good material appearance given the 0.5 hole diameter gives it a very smooth feel, however, it will reduce air flow in some component configurations requiring higher airflow.

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 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.

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!

Unfortunately, one of the filters was damaged in transit, or there was not enough glue on the magnet. The filter that WAS useable, however, I am pleased with. It looks sleek, and allows proper airflow with no temperature problems. Easy to put on, it’s just a magnet. Noticeably less dust entering my case since putting it on.

Good product, don't forget to clean them every so often.

No issues. Measurements are correct. Not bent/damaged. Magnets are strong and white color. NOTE: These do cut off a lot of airflow BUT it catches the very fine dust/fuzz very well.

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

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.

The mesh is high quality and durable, although a bit rigid. The 287x147mm size just barely covers a 280x140 rad, and if your rad doesn't come with pan/flat top screws, they will interfere with the magnets on the filter and leave a wobbly-looking top on your tower. The indent on a Corsair case with top rad support is much larger than the mesh as well, leaving gaps all-around it.
