[4 Pack] 400x300mm DIY PC Case Dust Mesh Filter
Excellent filter media. In fact, this filter material is indistinguishable from the filter that was included with the Lian Li 011 Dynamic EVO. I run an unconventional air flow setup in this case with the top and bottom radiators as exhaust and the side and rear as intake. So, I needed to filter the rear 120 and two vent sections on the side panel where air is drawn into the case. I was looking at much more expensive custom made filters, but read a lot of reviews about the rise in temps due to further restricted air flow. I am happy to report this DIY filter media cuts down on dust intake and does not negatively effect my temps. Cutting the material was super easy with a box knife and the magnetic strip's adhesive sticks well. Overall, awesome kit.

Good kit
Easy to install and good airflow and easy to make fit. Functions well and the magnet strength ismore than strong enough. Good for dust removal.

The magnets are pretty strong
Got a case that came without filters, and these worked great as a replacement. The filter is easy to cut, the magnets aren't hard to cut and apply, and they stick really well to the case. They also look good. Also haven't had any airflow problems. The temps stayed the same with and without the filters.

Good enough filter update for older case
I have an old CM Nvidia version case and had to constantly dismantle the entire case to clean the filters. Now I was able to remove the old ones and create new filters with this and a stronger magnetic tape. Not the best, but not the worst.

Works great!
I needed more ventilation so I opened the two fan vents on top of the PC case and added this filter. It works great for my purpose, and living in the country with dogs and cats in the house, I needed a decent dust filter. Cutting and fitting to size is pretty easy of you follow the hole grid. It's easy to pull up and clean when I need to and it stays put when I don't. I'd buy it again. The price is right.

Great replacement or addition for dust mesh filters
I replaced the front dust mesh filter on my PC with this and found it to be better than what the OEM used. I also removed a glass front for better airflow so I used a larger piece to cover all the holes where it originally attached. The magnets adhere to the mesh very well, I've taken the mesh on and off my case multiple times for cleaning purposes (dog, cat and 6 people in my house) and the magnets stay on the mesh without fail. One piece of advice: after measuring at least twice, bend the mesh before cutting it to give yourself a straight line to go by. Simply marking it with a pencil or marker didn't work as well.

Great materials and value
The pvc used is nice and sturdy. The magnets stick very well to the pvc and metal and they cut very easy. You can make 8 or so extra large filters depending on how big you need it. I was able to cut this large 355mm x 155mm bottom fan filter on my Lian Li case to replace the factory one. Perfect fit.

Just alright..
Unfortunately the adhesive is very poor on the magnets.. these are also hard to cut in a straight line

Eenvoudig te monteren.
Voldeed helemaal. Filters eenvoudig op maat te knippen of te snijden. Magneetstrippen werken goed. Blijven aan de kast hangen. En de stof wordt afgevangen. Wellicht niet het fijnste maar het werk al beter dan de de filter van de pc-kast zelf.

Resistente y maleable, ideal para DIY para atrapar el polvo en ordenadores y otros aparatos.
Resistente y maleable, y con un tamaño de malla excelente para atrapar el polvo. Lo he utilizado para hacerle una carcasa modificada a mi PC principal (la GPU de 2ª mano que le compré no cabía bien en la torre) y para tapar varias rendijas de otros aparatos eléctricos. Muy contento con el resultado en todos los casos.
