Room volume is the cubic footage of the room. To calculate this, multiply the length, width, and height of the room.
Number of air changes per hour is the number of times you want the air in the room to be replaced in an hour. (A good rule of thumb is to aim for 2-3 air changes per hour).
60 is the number of minutes in an hour.
For example:
If a room is 10 feet long, 12 feet wide, and 8 feet high, the room volume would be 960 cubic feet. If you want the air in the room to be replaced 2 times per hour, you would need a fan with a CFM rating of 320.
CFM = (960 cubic feet * 2 air changes per hour) / 60 minutes per hour = 320 cubic feet per minute
It is important to note that this is a general formula. The actual CFM requirements to ventilate a room may vary depending on a number of factors, such as the number of people in the room, the activities taking place in the room, and the type of ventilation system in the room. If you are unsure how many CFM you need, it is always best to consult with a professional.
Here are some additional factors to consider when calculating CFM requirements:
By considering all of these factors, you can determine the correct CFM requirements for your room and ensure that you have the proper ventilation to keep the air fresh, healthy and clean.
