## Air Flow Rate (CFM)
**CFM = Room Volume x ACH / 60**
ACH (Air Changes per Hour) is how many times the entire room volume is replaced with fresh or conditioned air in one hour. Divide by 60 to convert from cubic feet per hour to cubic feet per minute.

20 x 15 ft room with 8-ft ceilings at 6 ACH.
- Volume = 20 x 15 x 8 = 2,400 cu ft
- CFM = 2,400 x 6 / 60 = 240 CFM
