How to calculate CFM
To calculate the CFM (cubic feet per minute) you need for a room, you can use the following formula:

CFM = (room volume * number of air changes per hour) / 60

 

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:

 

  • The number of people in the room. The more people in the room, the more CFM you will need to remove the stale air and replace it with fresh air.
  • The activities taking place in the room. Activities that generate heat, such as cooking or exercising, will require more CFM to remove the hot air and replace it with cooler air.
  • The type of ventilation system in the room. If the room has a natural ventilation system, such as open windows or doors, you will need less CFM than if the room has a mechanical ventilation system, such as an air conditioner or furnace.
  • Type of filter being used. CARBON filters and HEPA filters have different CFM requirements, make sure you check the specs closely

 

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.
