Case Filtering Options

I recently rebuilt my computer using a Cooler Master HAF-932 full tower case and I'm looking to minimize the dust intake. The case has a 230mm fan on the side panel (at least I think it's 230mm) and not really any filtering aside from the honeycomb mesh. It's a pretty big area, it actually allows for the installation of 4 120mm fans, so I've been searching around for some type of filter material or fabric I could maybe cut to size and use there.

I wanted to ask if anyone knew of a place where i could order something like that, or even a manufacturer i could contact. I know the filters you buy for fan ports have that cloth-like material and if i could find some of that in bigger sheets that would be perfect. Something like 1ft x 1ft would probably work, i just need something there to reduce the amount of dust and other debris collecting on the fan and inside the case.

i have the HAF-932 too, its a dust magnet. i have to clean it out every other week

I have used this kind of woven metal screen, which works pretty well as long as it is fine enough, and it can easily be cut to size. Here's a link to a supplier:

You can go to "Woven Wire Cloth, and down to "Fine Mesh"

That looks like it would probably work, thanks.
