G3 - Premium dust filter material for PC case/fan 950x155x5mm (Black)

First than anything, the photos shows where I'm using it.At first I thought the airflow would be compromised due to how small the holes are, but I decided to give it a go due to how horribly dusty is the place I'm in.The results couldn't be better. The airflow has continued being perfect, the temperatures haven't raised beyond the expected (It's summer here, with temperatures over 38°C) and the black color fits well with the rest of the case.Another thing I feared was the filter's glue getting dry, but that wasn't the case. THe glue is firm enough.How effective it is? While there was still some dust inside of the computer when I opened it (I live in a very dusty place, after all) the dust was way less than how it was before installing it. How much less? I couldnt write "hello" on the PSU with my finger (The text was almost unnoticeable). haha.This is a great product, and the day I need to renew it, I know I'm going to buy another one.

My 5 mid tower computers were constantly filling up with dirt and dust. I cut the foam to fit over the intake vent holes, and the bottom where the front fan draws in air. You do get some sticky stuff on your scissors, but it is easily removed. Had them on a month and inside is dust free.It is easy to reposition the foam, as it come free the surface, and can be repositioned without leaving any sticky stuff on the computer case. This is for the # number 3 version, the foam is thicker then 1 & 2, making it easier to handle.

I spend a lot of time in the computer room, and I'm also a smoker. This product keeps my computer clean. I've used computers for over 30 years, and smoked for 25 of them. This is the only product I've found that keeps the inside of the computer clean. I don't bother trying to clean it, I just buy more and replace it every year. Works fantastic and is totally worth the money to keep the inside of your PC dirt/dust/grime free.

I expected the adhesive to be weaker than it has turned out to be. It felt just a bit weak to the touch, but it has held up well for me so far, even a small piece that I suspect I handled too much. Also, after a couple weeks constant usage in the dusty state of AZ, covering as much air intake space as possible, there's almost nothing undesired in my case! Minimal buildup on or around internal fans, and most importantly the radiator for my liquid cooler. If I need more of this type of product, I'll be buying this one again.

This stuff does work... sort of. Besides being very thin, it's also not very sticky, so it works best when used to cover an air intake from the outside. But then you can see it. If you put it on the inside, it can get sucked into the fan blades because the adhesive isn't strong enough when there's a fan trying to suck through it. You also can't really clean it... a vacuum sucks it right off of whatever it's stuck to, and because of the adhesive, air flow through it is reduced drastically.

This won't fit on the front of my PC so I wanted to return it, unopened and unused, but they would have charged me $6 for expensive UPS only. So it is not free returns, which wasn't made clear before I purchased it or I would not have ordered it. Most things on Amazon are free returns these days. The product itself is good (used previously) but the return policy is a disappointment.

Used this on a small 9U rack was easy to install, adhesive stuck well. I will note this wasn't used on the fans rather to cover all holes in the cases so that dust wouldn't be pulled in through venting in the case just the intake fans which have removable dust metal dust covers that can be cleaned. Also used scraps to reduce vibration on case doors. Price was a bit steep but works well.

Does what it says despite the poor English. The back is a little bit sticky, it wont hold for more than a few minutes but I think it's only meant to stick long enough to figure out how much you need, where you'll put it, etc. Definitely worth it if you're having dust issues or are ocd about a clean PC like me, where you'd have to pop open your case and spritz it up a bit every few days.Airflow remains the same roughly, but in the worse case scenario your PC might gain an extra 1 or 2 degrees.
