Hood Vent

Proper ventilation in your kitchen is absolutely necessary. Homeowners sometimes buy a hood simply because it looks pretty but they don’t take into account the CFM that they will need for their kitchen.

When you cook there is moisture, gas, grease and smoke. You need to make sure your kitchen is properly ventilating these things. Follow our guide on selecting the correct vent for your home.

What is CFM?

CFM is the acronym for Cubic Feet per Minute. This refers to the amount of air that your hood will have to filter. Your kitchen will require 15 air changes per hour that it is in use. To calculate the CFM needed when buying a vent you will need the following:

1. Calculate the cubic feet of your kitchen. Multiply the length, width, and height of the kitchen in feet. The number you get is the cubic feet of air that your vent will have to exchange at least 15 times in an hour.

2. Multiply the cubic feet of air times 15. Take your number and divide it by 60 since CFM is measured in minutes.

Calculating BTUs

3. Figure out how many BTUs are in your range or cooktop. BTU stands for British Thermal Unit and each burner has its own BTU. BTU refers to the amount of energy needed to heat one pound of water by one degree Fahrenheit. Add up the BTUs for each burner.  Multiply the total by 0.01 and add this to the number you got in step 2. This will give you the CFM necessary for your kitchen.

Select a vent that has the minimum, if not more CFMs. Make sure your home has adequate ventilation. What isn’t vented out can settle on your cabinets and leave lingering odors in your home. Take some time and do the math!
