CFM
CFM stands for Cubic Feet per Minute. CFM is used as a unit of measurement to describe the effectiveness of an exhaust fan. For example, an exhaust fan with 300CFM can move 300 cubic feet of air per minute. So if your tent is 300 cubicfeet,
a 300CFM exhaust fan could exchange all the air in your tent once per minute.
