How much airflow is required?
HVI recommends ventilation rates based on 8 air changes per hour. For most bathrooms this works out to 1 cfm per square foot of area, with a minimum of 50 cfm.
A bathroom less than 100 square feet:
Calculate 1 cfm per square foot of floor area. A minimum of 50 cfm is the required ventilation rate.
A bathroom larger than 100 square feet:
To calculate the proper ventilation rate, add the cfm requirement for each fixture; toilet 50 cfm, shower 50 cfm, bathtub 50 cfm, jetted tub 100 cfm. Note: For proper sizing, the static pressure (SP) needs to be calculated.
