140mm x 2 Magnetic Frame Dust Filter, Computer Dust Filter and 140mm x 2 Fan Filter Set of 2

Worked great no complaints.

These screens are flimsy mainly because of the flexible design, On the other hand, making them of a stiff material just wouldn't allow the flexible magnetic edges to adhere so well. They send 2 of them, so if one craps out I'll just use the other. The screen looks like it will catch dust and be easily cleaned.

Definitely worth the money. They do the trick. Easy to remove and clean.Case I purchased was lacking in filtration in a couple of areas so these filed the bill.Magnetic attachment makes thing easy.

The size was just perfect, and you get two of them. It did feel cheap, I mean it is cheap but, the magnets will hold but they could be better. Overall it is useful and will serve its purpose

I had high hopes until I saw the product up close and did a quick test using a vacuum cleaner in reverse and some dust. I had been using a competitor's product that had ultra fine mesh and cost 4 times as much per item. With the vacuum running in reverse I sprayed dust on both products and the one with ultra fine mesh stopped all the dust from going through. This product however stopped some of the dust but still allowed a significant amount to pass. In reality this amount of dust would never be seen all at once and in all likelihood the bulk of the dust would have been sucked into the computer. There is a reason that ultra-fine mesh products exist. I take them down once every other week and give them a quick cleaning with the brush attachment on the hose. These went back and the ultra-fine mesh replacements at 4 times the price were purchased here on Amazon. I will write a review on those shortly

These do exactly what they claim to do, and I don’t even have them properly installed due to my hideous case that I am replacing asap. I have them on the outside of the grills and vents as opposed to the optimal placement which would be within the case. Even so, these block a TON of dust and debris from entering my computer case and settling in for the long haul in the nooks and crannies. Whether you need a quick temporary fix, or a long term permanent solution, these should do the trick.

Bough these these to filter intake air after adding more fans to wife's Cooler Master case. We have already lost 3 fans to hair and dust getting in and winding around the fan. They've been in for a couple of months now, and these have fixed the problem. :)

Good product for my need. Fast ship!
