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

Worked great for spider-man lenses

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.

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

What it says on the tin, but I'll also add that it is very obstructive with small holes spaced moderately apart.

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. ->->-> [] ->

Fits perfectly

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

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!

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've seen a big difference in the amount of dust and dander.

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.
