Review on 🔌 2-Pack of Magnetic Black Dust Proof Filter Covers for 360mm and 120mm x 2 PC Fans - PVC Computer PC Case Dust Mesh Filter Cover, 4.72inch by Jon Conner

Looking through the comments I've seen some reviews say they don't hold up well but to be honest they hold up great, at least for me. In fact, they also look very nice, the edges are very well rounded, there are no creases or damage, and overall the construction looks great. They're great at catching dust, I'll give them that. However, they severely restrict airflow and the holes are SMALL. This isn't a problem with the PC I used it on because I just wanted to close the unused fan grills to keep the CPU cooler from letting unfiltered air through the sides and top. But if you need strong airflow for your PC, this will greatly reduce it. Blowing through them feels like a 50% reduction in flow.
