I'm in the planning stages of a fully scratch-built PC (I'll post a log when I have something to show off), and I want to add some filtering on the incoming air. I find that this isn't a very common item to just pick up pre-built though. I've found only a couple of filters designed to fit onto fans, and they're pre-modded with a visual motif (spider web, etc.) that I would have to remove first.
So I got to thinking about what it would take to make a filter myself. Just something simple and inexpensive that I could replace every other month or so to keep the inside as dust-free as possible.
Anyone ever try this kind of thing before? I was thinking using some kind of dusting cloth as a base, but I need good air flow through it as not to stress the fans. Swiffer cloths? Part of a vacuumn cleaner bag?
Any other ideas you guys can come up with?

After posting, I realized this probably would fit better in Idea Zone. Mods, feel free to move it if you feel the same.
