I'd like to build a cr box for my bedroom which tends to accumulate a lot of dust in teh warm months when the windows are open, and while I love the resourceful and industrious design of the cr box, they are, well, just kind of ugly. I love many of the DIY solutions on this sureddit, like all the wooden encasements. I have a design in mind for a cylindrical DIY filter and am curious if any one has tried this already?

thanks!
