How much airflow is required for bathroom ventilation?

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.

What is HVI?

HVI, also known as the Home Ventilating Institute, is an independent non-profit organization that certifies fan performance characteristics and provides HVAC guidelines for consumers. Learn more about HVI at HVI.org.

When it comes to choosing the right duct, people often ask, “What is the best duct for bathroom ventilation?” While there isn’t necessarily one absolute right choice, many times the best option is the flexible insulated duct.  Learn more in our blog posting:what-is-the-best-duct-for-bathroom-ventilation
