What is the difference between a range hood and an exhaust fan?
The range hood requires pipes that connect to a duct to transport the dirty air and foul odor away from the kitchen to outside. The exhaust fan effectively gets rid of the moisture in the kitchen that arises due to an increase in moisture and vapor from food preparation, a feat that the ductless fans cannot.
Does a stove need an exhaust fan?
Yes. Gas stoves produce intense heat and smoke, so you need a kitchen fan that can vent heavy cooking exhaust outside your home. Buy a range hood that is at least 900 CFM to keep your kitchen air clean and fresh.
How many CFM do I need for range hood?
To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.
Is it code to have an exhaust fan over a stove?
In restaurants, vent hoods are required. This is what the ICC Mechanical Code says: “Type I hoods shall be installed where cooking appliances produce grease or smoke as a result of the cooking process.” Commercial vent hoods require make up air and a fire suppression system to ensure their safe use.
How do I choose an exhaust fan for my kitchen?
- The size of the exhaust fan is the main criterion for selecting an exhaust fan for the bathroom (or kitchen). The airflow or amount of air exchanged per minute by the exhaust fan is measured in CFM (cubic feet per minute).
- The preferred location of the exhaust fan is near the shower area or the bathtub of the bathroom.
Do ductless kitchen exhaust fans work?
Yes. However, they are not as efficient as ducted range hoods that vent kitchen air to the outside of your home. Ductless range hoods use charcoal filters which trap some grease and odors but are not as effective as the stainless steel baffle and mesh filters of ducted range hoods.
What can I use if I don’t have a range hood?
10 Things to Do If You Don’t Have a Range Hood or Vent

How do you size an exhaust fan for a stove?
Range Hood Ventilation The new hood should be at least as wide as the range or cooktop and preferably 3 inches longer on each side. The most common widths are 30 and 36 inches. For optimal performance, install a hood 20 to 24 inches away from an electric cooktop and 24 to 30 inches from a gas cooktop.
Do I need a vent hood for my gas stove?
Generally, in the U.S., you don’t have to vent a residential gas range to the outside. But, we recommend that you buy a range hood to vent contaminants from your gas range to outside your home. It will dramatically improve your indoor air quality and reduce the risk of long-term respiratory problems.
