How do I know what size extractor fan I need?

To size a bathroom extractor fan, calculate the required airflow (measured in cubic feet per minute or cubic meters per hour) based on the volume of the bathroom. Use the following formula:

Required Airflow (CFM) = Bathroom Volume (cubic feet) x Air Changes per Hour

For instance, if your bathroom is 8 feet long, 6 feet wide, and has a ceiling height of 8 feet, the volume would be 384 cubic feet (8 x 6 x 8). For standard ventilation, aim for about 8 air changes per hour. Therefore, the required airflow would be:

Required Airflow = 384 cubic feet x 8 air changes per hour = 3072 CFM

Select an extractor fan with a capacity close to or slightly exceeding this calculated airflow. In this example, a fan with an airflow rating of around 3200 CFM would be suitable.
