I've bought these before from other vendors and from overseas and while these on amazon are kind of high priced I have to say that what I received from Eluteng Direct was quite a bit nicer. It's real ABS so tough enough not to break easily but still has some flex to adapt to different fan surfaces and when removing the cover. The molding quality is top notch with literally no sharp edges or sprue to trim - pretty rare to see that in molded parts. The dimensions are spot on for outside and screw holes. Inner grill is about 4.5mm thick, and the mounting pads stick out ever so slightly from the other edges (less than 0.5mm)...not enough gap to worry about but the fan will matter more there. Outer grill/cover is 10mm thick and that's what you get when installed. The foam is so-so, about 3mm thick and pretty tight pores. There is room to fit a thicker more open foam like aquarium filter foam and the 6mm stuff I have here fits nicely - has a little more air flow by breath test but that doesn't mean much in real operation. Foam smells like normal fresh foam to me, nothing harsh or "toxic" as mentioned in another review...if yours smells when you get it then it'll stop after some exposure to oxygen or you can speed it up with sunlight time. I picked these up to pair with an a/c high flow fan ( www.amazon.com/gp/product/B009OWRMZ6/ )to DIY a smoke absorber for soldering and I think they'll work great together. Previous ones I've used for case fans did fine although they came with a different foam. These do a better job than plain magnetic screens if you have a lot of dust or pet fuzz floating around but they do restrict flow a tiny bit - depending on your case's design it may or may not matter at all (could actually improve things).

I find it really strange that these would ship with a screw driver, but no screws. Kind of a headscratcher. And a flat head screw driver at that, i dont think i have ever seen a flat head 'fan' screw, especial one as small as the screw driver would be useful for. Just weird. Otherwise perfectly acceptable, didn't expect, but really like the double layered design of this, the filter is placed in between two frames, works very nice, once you find some screws!!!!

I got these to cover some vent holes that I drilled in a cabinet for a built in mini fridge. I didn't want to just have holes, even though they can't be seen, I liked the idea of covering the holes. They are made of a light weight plastic and there is a small foam layer in between the pieces of plastic. I drilled 1" holes and these worked perfectly to hide the holes. The foam layer is a dust filter, so that's an added bonus. Only thing I will say is that the plastic isn't that strong. It's easy to break the tabs that hold the pieces together when you are removing them to mount it. Also, on that's same note, use a screwdriver and not a drill. A drill will split the plastic if it goes too tight.Overall, very happy with them. I would purchase again if I ever needed to cover some small holes.

I used this filter on a custom built virtual pinball cabinet. I installed a fan in the bottom of the cabinet, which draws air in. It was blowing in dust and cat fur, which was then settling on the playfield screen. I bought this filter, and it has worked well so far. It has been installed for about 2 weeks, and has not clogged yet. The housing is solid, and I like that the filter can be replaced from outside. Coming with 2 housings and filters was a nice plus. This has worked great for my application, and I highly recommend it.

If I had it to do over again, I would not buy this product. The "filter" is about as good as you might expect from a cheap product. The grill front on the device is difficult to remove.I ended up not using the filter itself and used the flimsy plastic structure to act as a fan blade protector.

I bought these, along with a set of fans, to pull air through a cabinet I made to run external hard drives in. These filter the air on the intake and cover the fans on the pull-through exhaust. They are easy to install, have a nice cleanable filter, and were an excellent purchase for my needs! I particularly like the way they look, as the screws holding the whole unit in are hidden, and the filter is easily accessed for cleaning.I've had these for about two months.If I build another cabinet (and I may for my Audio equipment) I will order them again!A top buy for what they do!(Unpaid, unsolicited, and unbiased!)
