My basement dimensions are about 30’ X 50’ X 8’, a volume of 12,000 cf. How big a blower is needed to exhaust dust so that little gets upstairs into the house? I’m not overly concerned about personal safety when working in the basement because I wear a mask when I sand. It’s my wife who has COPD that I’m worried about. Windows located at one end of the basement and stairs at the other should provide enough air flow to keep the upstairs clean. Is there an advantage to installing two blowers such as reduced noise? Advice will be greatly appreciated. Thank you.
