How much airflow is required?

The following recommendations follow minimum guidelines published by the Home Ventilating Institute (HVI):

  • Bathroom less than 100 square feet: – 1 cfm per square foot of floor area. A minimum of 50 cfm is the required ventilation rate.
  • 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. For typical applications, you may read from the 0.2” SP column for a selection.
