Every exhaust fan has a Cubic Feet per Minute (CFM) rating which shows how much air the vent can move. To be the most effective, the CFM rating of the exhaust fan should be at least half of the cubic footage of the bathroom it will be operating in.
How much airflow do we need to ventilate? Area Method. Derives the ventilation rate from the area of the space (in square feet) to be ventilated multiplied by the ventilation rate per square foot. Example: For residential bathrooms up to 100 sq. ft. in area, HVI recommends an exhaust rate of 1 cfm per square foot. A bathroom is 6â² to 10â² or 60 square feet.
