MASSCOOL 120mm ABS Plastic Foam Cooling Fan Filter, Pack of 2 (FG-2P-120MM)

Not well made, but they're not supposed to do much. Filters themselves good for larger particles. Fine dust passes straight through, but on the other hand you don't want to choke up the fans. They DO NOT work in a tight side by side (eg. top/bottom on side panel) fan mounting. The outer case extends beyond the normal screw hole pattern. The base plate screws on fine, but the tops get in each others way trying to clip them on.All in all, they're fan cover/filters...they work. I recommend the Silverstone. They look much better, fit side by side, and have a tighter filter...but Amazon has their prices all screwed up right now...$22.00 for a piece of plastic? If they ever get around to putting the price right at $2.49...the Masscools will find a shelf. I prefer that all my builds to look essentially alike.SilverStone 120mm Fan Filter with Grill FF121B (Black)

i put two of these inside a small beverage fridge that i placed two 120 mm fans in. They help circulate the cold air inside and when reaching in the grills prevent the fingers from being chopped by the fan blades. worth every penny. They fit exactly.

Nice grills and the professional finish and protection are worth the investment for my installation. They fit perfect and will keep any unwanted elements out of the fan blades and safety of the Noctua fan they are mounted to. Thanks!

Keeps dust away, easy to clean.

These fit perfectly over the two 120mm fan slots on the side of my case. After being bolted down, the front still snaps off easy for access to the filters.

Sturdy and cheap, not much else to say. Using these on fans mounted to cool my media cabinet, to help keep fingers safe.

High quality covers for fan, very rigid, nicely chromed and all.Comes with no screws, too bad indeed. a b
