Use Your Room Dimensions and Custom Cubic Feet Per Minute to Calculate Air Changes Per Hour

To calculate the changes of air you need, start by entering the dimensions of your room to produce the total square feet and cubic feet. If you know your room has a specific custom airflow enter that as well. Once you’ve entered your information, calculate the cubic feet per minute. Your results will tell you how much CFM you will need to change over the air in your room as well as the capabilities of our equipment and how many units you would need for your application.
