140mm 5.5inch Magnetic Frame PVC Dust Filter Grills - Computer Case Fan Dust Proof Cover Black for PC Ventilation & Cooling Systems 5-Pack

Great quality, easy to install, they catch dust greatly and they are really easy to clean. They fit my computer case like a glove. Great value for theur price, durability and functionality. I would buy them again if I had another computer. They last forever!

The item is exactly as described. I ordered magnets to go with it. I measured and cut it to size for the side of my PC. It visibly blocks dust too. It does kind make the RGB and screen a little blurry to look at, but that's expected with a thick mesh. It also makes it super easy to access my case because I can just pull the mesh off and snap it back with the magnetics. It makes the case so much cooler too. My temps dropped by at least 10, maybe 20 degrees. Definitely worth it if you're wanting the most airflow in your PC.

Looking through the comments I've seen some reviews mentioning that they don't seem to stick well, but honestly they seem to hold themselves on perfectly fine, at least for me. They actually look really nice too, the edges are rounded off really well, they have no creases or damage whatsoever, and overall construction feels great. They do a great job catching dust, I'll give them that. However they restrict airflow a ton, the holes are TINY. This isn't an issue for the PC i used them on, because i really just wanted to cover the unused fan grates so the CPU cooler would stop pulling unfiltered air through the sides and top. But if you require high airflow for your PC, these are going to cut it down a good bit. Blowing through them feels like a good 50% reduction in flow.

Perfect, but for my pc its a little small

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.

I did not like the bonding of the filter to the magnetic material, the adhesive that holds the magnetic material to the filter is defective-one filter had the magnetic material loose in the package, and the other had moved completely onto the screen filter, after removing the magnetic material that had moved it left adhesive on the screen filter. After cleaning the adhesive off and installing I found that the screen vent hole size that I selected is too small for my use, it does inhibit foreign material from entering the PC case, so much that in my case it inhibits intake air flow causing heat buildup. I will not be using them so I will not know if they are easy to clean. They are easy to install and remove. I do not recommend if used as a PC case intake filter.

This combined with a new thermal pad has increased my pc functionality by dropping my temps along with a new thermal pad at idle by at least 20 degrees Celsius. This is a good quality product, and given the results I would say a good value for my money. The fit and sizing are very simple as long as you know to measure twice and cut once. I imagine it will also make cleaning much easier as well. The complaint many users have mentioned about the pvc curing can be resolved by rolling it in the opposite direction and storing it in the tube for a short time. I have included a short video clip below verifying how flat it fits when installed properly.

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 :)

Literally what's on the tin, a flexable fine mesh with magnetic connection on the back, fits perfectly on a 360mm aio/fan block

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.

I work in a very dusty warehouse. Our old stereo died from what I'm guessing was a decade of dust and neglect. I bought a new component receiver and it had all these giant hole vents on top, so I bought this to cover the openings and so far it has worked like a charm! I even bought a few more to cover the side venting too.

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