"That means a 70CFM fan will move 70 cubic feet of air in one minute.
Your fan should be big enough to move the volume of your area 2 to 3 times every minute. A 70 CFM fan would be adequate for a 35 cubic foot area, and would be optimal for roughly a 23 cubic foot area."

Is this correct? a 70CFM fan can clear 70 cubic feet in one min... so couldnt it clean a 350 cubic ft room in 5 mins?
