YIMATEECO 120mm Fan Filter PC Dust Filter for Computer Cooler/PSU/Routers PVC 50 Mesh, Magnetic Frame Dustproof Case Cover Fan Grills (PVC, 120 * 120mm, 2pcs, White)

These do the trick! Perfect fit, and much easier to deal with than the actual case fans. They filter out quite a bit from my dusty house. Super fine dust still gets by, but considering how MUCH dust I have to deal with (everyone in the household works blue collar and this is in the main living area) it's been fantastic. Quality is great, functional, looks good, no complaints.

There are perfect! I bought 2 of the nylon dust screens for my SFF console build intake fans. I have a corgi and the dust and hair is crazy in my house. They filter with ease and without hindering airflow much. I didn’t expect the magnets to hold the fans, but they do! Highly recommend!

Most of these things are about the same. A thin mesh nylon sheet, somehow adhered to a vinyl frame with weak magnetic strips. Slap 'em to the outside of a case, or even mount directly with existing fan mounting screws. These models in particular come with "Nano Gel-Mat" pads, which are the little white YAMITEEC branded strips you see in the product imaged. These pads can optionally be stuck... somewhere. For some purpose. I have no idea what the intended function of these little pads are, but they didn't come packaged with similar nylon screens from other vendors... so... that's a plus, I guess. I suppose you could hypothetically use them between a fan and case to reduce vibration. Possibly between screen frame and fan, for similar purposes - though the pads will not run the length of your fame and create a gap for dust to pass. These little things are throwaway, for me. But mentioning it just the same in case anyone else has a clue. There's not really anything to say. The models I purchased were 120mm and fit accordingly, and nylon screens do what you expect - filter way more than just about any other screen, without significantly affecting airflow. TECHNICALLY they will, especially as they get caked in dust, but that is also where nylon excels being so tough and easily cleaned. So long as you don't mount these with screws, you can just peel the thing off give it a quick dust, or even rinse, and slap it back in place. EZ. Highly recommend nylon case filters like these over any PVC. No difference in cost, so no reason otherwise, unless you REALLY need something rigid, like directly against an exposed fan.

I'm using these dust filters on fans inside my plant cabinet. In order to prevent dust it makes sense these would go on the back of the fan where air is coming in toward the blades, right? However, by doing this, it seems to slow the air flow significantly compared to the fan without the filter. I'm not sure that it matters for me but it is something to take into consideration.

I really like these dust filters. They have a good amount of mesh to keep out dust while allowing good air flow. The magnetic edges are a plus. I expect the inside of my case will remain a lot cleaner.

These dust filters are great for my pc that don’t have some. I have used them for about a month and my pc has little to no dust inside because it catches it. It preforms good and airflow is great through then.

Keeps my PC dust-free. Works perfectly. Easy to use. Easy to clean. The airflow is clean and healthy.

This is being used to lightly filter the air going into a cabinet install where I've used 6 120mm fans to cool my Xbox series X. 4 intake and 2 exhaust with these filters on the intake are proving a great ration to keep the cabinet under slight positive pressure. Ensuring any air entering is through these filters. So far I see very little dust get by them, and they were very straight forward to install. The surrounding bezle is in fact pvc, and is malleable, so if you intend this to be the sole sealing surface with no support, and must rely on a seal, you will want a metal bezle or something of the sort to ensure a decent seal. These have been more than adequate for my purposes. There was some slight separation between the layers as the screen seems to be sandwiched between two layers of pvc, but not enough separation to really see failure or how the pvc is actually laminated. I would need to use a knife to pull it apart more, so it's not something I would really consider a flaw, unless those separations become an issue in the future. As of right now they are serving my purposes perfectly.

I got this for a PC in a sometimes dusty environment (the garage) and the filters are good quality and attach easily and would definitely keep out a lot of dust but they had too big an impact on the airflow, way more than you would imagine to look at them. In the end I tested by blowing on my arm and then moving the filter in between and ... wow, you suddenly hardly feel a thing! Ultimately my fault for buying the wrong thing, but consider getting a less fine mesh version unless you know you really need that level of filter.

Fa benissimo il suo lavoro. Non c'è bisogno di avvisarla perché è magnetica e filtra moltissimo. Consigliata

10/10 would buy again. Nice and reusable, collects dust and easy to clean. It was easy to install.

Ok jest dobrze! Jednak siatki powinny być żadsze bo te mogą szybko się zapychać kurzem. Samo założenie siatek to zmniejszenie przepływu powietrza o 10% a po dwóch tygodniach nawet 30% więc nie zapomnij ich czyścić.

Bad seal if you use screws for Corsair LX/LX-R/RX 120mm fans, but "works" alright if you just use the magnetics. Possible to make it work with screw with a bit of DIY. Packaging is terrible for the tape things, if you plan to use those. Half were unusable. Overall, decent for the price.
