In the future us this formula.
Say you have a 10 x 10 x 9 foot room. That would be 900 cubic feet. Simply divide the cubic feet of the room which is 900 into the CFM of the fan which is 300. The answer would be 3. That means that a 300 CFM fan would exchange & clean the stale air of that size room within 3 minutes. Afan should remove stale airfrom aroom within 5mins. So yes a 300 CFM would be good if you have similar specs.
