CFM (Cubic Feet per Minute)
The amount of CFM (Cubic Feet per Minute) of air required for a kitchen depends on the size of the kitchen and the appliances used. The Home Ventilating Institute (HVI) recommends a minimum of 100 CFM for every 10 feet of kitchen area.
For example, if your kitchen is 12 feet by 12 feet (144 square feet), the minimum recommended CFM would be 1440 (144 sq. ft. divided by 10, multiplied by 100). However, if your kitchen has a high-output range or cooktop, or if you frequently use a deep fryer or wok, you may need additional ventilation to remove excess heat, smoke, and cooking odors.
It’s important to note that proper ventilation is critical for kitchen safety and air quality, as it helps to remove excess heat, humidity, and cooking byproducts, such as carbon monoxide and volatile organic compounds (VOCs). If you’re unsure about the appropriate CFM for your kitchen, consult with a licensed HVAC (Heating, Ventilation, and Air Conditioning) professional or an architect.
