How Many CFM's Do I Need For My Range Hood?


This is one of the most common questions we are asked here at Proline. Let’s talk about CFM requirements and how to calculate the CFM you need to make sure you’re keeping your kitchen clean and free of lingering smells and harmful fumes.


The ventilation power of your range hood is measured in cubic feet per minute (CFM). This refers to how many cubic feet of air the range hood is exhausting for every minute of operation at full speed. Simply put, the higher the CFM, the more air the hood can remove.


To determine how much CFM you need for your range hood, consider the following:

  1. How often do you cook?

  2. What cooking style(s) do you like?

  3. Is your range gas or electric?

  4. How many BTUs is your kitchen range?

  5. How wide is your range hood?

  6. How long is your ductwork?

There is no ideal range hood CFM, but instead, an appropriate CFM based on your cooking style and habits in the kitchen. The best range hood is different for everyone and depends not only on your cooktop but on your cooking and lifestyle as well.
