Summary: Great fan filter. Works well to keep cords from getting into the fan, which is one reason I bought a few of these. Easy installation (although it doesnt come with screws) the ones that come with your fan can easily be used to install both this item and the fan itself.
Summary: Best fan filter. Keeps dust from my side case intake. Don't bother screwing to fan/case to make it easier to clean. The magnets are not that strong which makes it easy to take off (good and bad).
