I'm building a bunch of bookcases in my basement workshop. I need to control dust and I'm considering the following:

2 box fans in a frame facing opposite directions
furnace filters on the top sides and bottom

the fans will suck the air through the filters and clean it, while generating a nice breeze in the area

Is there a better (and similarly cheap) way to accomplish the dust control? I don't have an easy way to vent to the outside.
