How many CFM do I need for range hood?

Secondly, is 900 cfm enough for range hood? If your ducting matches your ventilation power, your range hood will do its job properly and quietly. A good rule of thumb for estimating ducting diameter-CFM requirements is: 6” to 8” duct = 400 to 600 CFM. 7” to 10” duct = 700 to 900 CFM.
