I am planning on getting or building an air filter for my basement-shop. Since there’s no walls or anything dividing the space, the entire basement needs to be used for sizing the blower.
My question is, how fast do I really NEED to circulate all the air in the shop? Most plans I see call for circulating in 5 minutes – which means a pretty big blower for a modestly sized basement space (between 6000 and 6500 cu ft, which requires a 1200-1300 cfm blower for 5 minutes).
I assume if it takes too long to circ the air, then more dust will settle instead of getting filtered – but does anyone have a good idea about where the cutoff should be? Can I do a 600cfm blower and run it for 10 minutes and still have good results? What about a 300cfm for 20 minutes?
Any thoughts are appreciated.
