12 Pcs 80mm PVC Black PC Cooler Fan Dust Filter Dustproof Case Cover Computer Mesh

These dust screens are great, and easily cleaned and good quality.

Seems like they are working just fine with some low airflow fans... at least they are collecting dust.

Fits perfectly

Used this to make lenses for a Spider-Man cosplay and I have to say It works very well for what I need it for. Just don't paint it with too heavy of a coat and the paint won't clog the holes.

100% would recommend for all computers. I have 2 dogs in my house and there is dog fur everywhere, I have these mounted on the outside of my case on the side panel with the fans as an intake for the PC. Its been about 2 months since I installed them and the inside of my computer is so much cleaner and I dont see any build up of dust yet. I will note that as they are mounted on the outside I can see what gets trapped by these things. I can pull off a hair/dustball that is bigger than a quarter almost daily. My biggest concern what the size of the holes I was afrad they would be too big to be effective. The holes are needle size pinholes very tiny and any air loss is negligible for cooling.

Easy install they are plastic so you can cut them with scissors if you need to maybe as a retrofit or custom fit holes are pre-punched and since they're plastic easy wipe down they're flexible don't have to worry about paint chipping or anything like that

Love the screw hole knockouts, these fit the 140mm fan configuration perfectly. They're sturdy and provide good airflow but stop fine dust particles. They're PVC plastic so they're washable, but for the price, it doesn't hurt to throw away and replace. Seller shipped immediately, the product arrived sooner than expected, in perfect condition. Highly recommended!

Very fine micro technology. Protects system very well against dust. I will definitely use these on all my intake fans where a similar filter is not available

It's quite useful product to avoid dust particles to b set into the computers or ur device's

Muy buena calidad. Construidos en pvc con buena flexibilidad. Atención que aunque el paquete pone 80mm en realidad lodad tienen 120mm de lado. A mi no me importó para nada, porque yo necesitaba modificarlos de cualquier forma ya que mis ventiladores tienen montaje sin tornillos. Muy fáciles de modificar a medida con tijeras o navaja.

Works as expected. Do bot forget to clean them once in a while.

I have a pre built Cyberpower PC. The PC did not have any dust filters, so I purchased these as they just screw into the fan holes directly with your fan. It works well, limits the dust for sure, and I haven't seen any increase in temps as well. Recommended!!

Son filtros buenos y baratos, reusables y faciles de quitar, limpialos con una tela humeda o en agua y listo. No los dobles que son medio rigidos y pueden romperse.
