Summary: Be aware that the filter material in this "filter" will only stop pet hair or spiders or other large objects. The filter material spacing is quite large and will allow average house dust to pass right through. Also, it does include mounting screws, however, the holes in the filter assy itself are larger than the grip area of the screws. The screws are not meant to be installed to the filter itself but rather a plastic frame of a fan.
Summary: Personally, i find these filters to be flawless. They look great. And function just fine. Some reviews say they block 50% airflow but i think they just have cheap fans because i can still feel my fans sucking plenty if air through. I use the bitfinix spectre pro 120's. These fans are especially perfect for this filter because they come with rubber screw mounts and the filter perfectly installs onto the little balls on the end of the mounts on the outside of my case.
Summary: Having a white cat that is literally a fur ball can be a nightmare if you have some black t-shirts... or a PC, and worse if you have both. A couple of these solved my PC issue, as for the clothing....
Summary: Got this for my pc, there is a large fan grill on the side window of the pc. since I have dogs and I keep my pc on the floor, the graphics card will get very dusty. Good thing I bought this filter when I first got this pc, it kept my pc mostly clean and I could see a lot of dust build up on the filter after a month.
Summary: The filter does exactly as it is supposed to. I have it on the bottom of a NZXT tempest 410 and it does wonders. Easy to install, easy to clean, and includes hardware. I would definitely recommend.
