I have been tweaking all aspects of my my dust collection system and am now to the point where I think an air filter might be the next logical step. I have not ruled out a "store bought" filter like the Jet, but am considering cobbling something together. It seems like something could be done without much expense.
Does the Jet, Rikon, Wen, or similar actually do much more good than a box fan with a high end filter designed to be used with central air?
I am thinking of a 20"x20" box fan with a 20"x20"x4" electrostatic pleated air filter. My initial thought is to hang it from the ceiling flat wise and blow the air up. Does that sound like a reasonable plan?
