>Greg, the smaller units will work under a table or a bench, just so the air into and out of it isn't blocked.
I built mine, using an old central Air and Heating fan. Built a box so the air would have to pass through four filters. You can get washable filters, for it, also. You could get a filter of the appropriate size, and build to fit.
Just my suggestion to think about. :o)
Good luck in your quest.
