I use a Sharper Image Ionic Pro unit in my train room with great results. This unit, coupled with our HVAC's static percipitator keeps the room dust-free at all times. Approximately once a year the room requires some light dusting. Unfortunately even rebuilt Image Pro units are expensive (~$200+)...but are well worth the expense.
If you are anticipating working with plaster, or drywall compound, do not sand. Use a wet sponge instead for dust-free leveling. [Incidentally most household dust is a mixture - the majority of which is human skin cells.]
