Bgears Fan Filter 120mm Fan filter with easy removable cover and washable foam filter

Pros: Good design for easy removal.

Cons: N/A

Other Thoughts: To the reviewer who said these won't mount to a case:

You simply need to get a few nuts and bolts. Pass the bolts through and tighten the nuts on the other side and these things should mount perfectly.

Pros: Keeps PC clean
Dampens fan noise

Cons: EXTREMELY reduces airflow. I'd say by about 75%

Pros: What can i see, this is awwwwwwsomee

Cons: My pc fan died lol

Other Thoughts: This is what it should be

Pros: good price for 2 look good removeable filter.

Cons: none reviewer kc all is not lost read other thoughts.

Other Thoughts: kc -(bolts & nuts or rivets )will attach these to the case no fan needed.

Pros: Cheap

Cons: Cheap

Other Thoughts: The mounting design of these filters is annoyingly lame.
1) They will ONLY mount to a fan. I was hoping to mount them directly to the case, to cover fan vents where I don't want/need a fan. But the plastic only has through-holes for the screws, not holes into which the screws could thread.
2) The screws effectively mount the bottom half of the filter cover to the fan, then the top half snaps on to the bottom half. The problem with this is that it then becomes very difficult to open the filter cover once it's mounted, especially in hard to reach areas of your case.

I'm going to drill some holes in the top cover of the filter and see if the fan screws will bite into that. If not, these were a waste of money for me, as I don't want to mount them to a fan (all my fans suck air out of the case, so filters are not necessary on the fans).

Pros: They worked pretty good until they got clogged with dust and the foam ended up ripping, so I ended up replacing the foam with used dryer sheets, they seem to work better, and allow for more air flow.

I'd reccomend just tossing the foam and just using used dryer sheets instead and just replacing them as needed.

Cons: Foam isnt great.

Pros: They had free 3 day shipping when I ordered them.

Cons: They come with pointless covers, the foam ripped itself, and I ended up not using them because I couldn't get the fans on with them on top.

Other Thoughts: I hate rating products too low.

Pros: Seems to do its job well.
I like that you can mount it on rear of fan, then snap out the filter without removing screws.

Cons: -1 egg
No screws included, Make sure you have some spare ones laying around if you plan on attaching it on other side of fan.
(Luckily its not my first rodeo cow boy, I got alot of spare stuff for many previous builds)

Other Thoughts: Old school style filter, Not the prettiest but when attached on rear of fan on mnpctech window with two 120mm's its not visible. Excellent solution on Corsair 600T that is now filtered on my window also. No more dust yay!

Pros: They're filters. They filter out dust. Not an electronic, don't have to worry about DOA.

Cons: The shroud the holds the filter is HUGE. On my NZXT Zero, I can barely get the side of the case on due to the covers on the back. Or, I should say cover, rather. They're so big that I could only fit one on, there wasn't enough of a gap between the fans to get the 2nd one on.

Other Thoughts: If your fans are spaced out and you have plenty of exterior room, get these. Otherwise, look for a smaller option.

Pros: Inexpensive. After a little more than a week and about 15 hours of run time I can already see the dust collecting on the front of the filters.

Cons: Fit and finish is not great. If you are big on aesthetics, these may not be for you.

Other Thoughts: Be mindful of the fans you are paring these with. I got some cheap 1200 RPM fans to go with these and they are barely pushing air through the case. In fact, the 2 exhaust fans are being limited by 3 intake fans with these filters in front.
