12 Pcs 120mm PVC Black PC Cooler Fan Dust Filter Dustproof Case Cover Computer Mesh

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!

Used these for a custom project. Performed as expected. The screw holes are scored so you need to punch them out with a phillips screwdriver or similar tool.

The media could not be loaded.  Good for keeping dust out while having ventilation. However, if you point a fan towards the mesh it will greatly reduce air flow on the other side of the mesh.Example picture each arrow as a level of flow.->->-> [] ->

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.

What is not to love about these? In spite of being very thin, these things are really effective at catching dust. Be aware that they do present a very slight airflow restriction, but anything you put in front of a fan will do that. Just make sure to keep these filters clean! Just take the filter out and use compressed air to blow the dust out and replace. You could also use warm water to flush out the dust. I do not recommend using any kind of soap, just plain water will work fine...just remember to let them dry before reinstalling them.They get the job done and are worth the investment.

Spray paint them white, boom good Spider-Man lenses

I have an older case without fan filters and these work great for keeping the dust out. They will reduce the airflow of your fans, but its well worth it. What I like most about these filters are they are firm, so they are not sucked into the fan blade while in operation.

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.

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!!

Es passt für denn Einsatz. Gut Verarbeitet.

The filters are fine, they haven't raised my temps at all. I ran Prime95 and my CPU is staying at the same temps as it did before. If it has done anything its within a couple of degrees.They kind of buckle a little bit over my fan as they dont fit 100% perfectly but that may just be a slight variation in my fans screw position.

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.

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