So here is my list of The 10 Best Range Hoods.
Is 600 CFM hood big enough?
The Home Ventilating Institute recommends a minimum of 40 cfm for every linear foot of your range. That means a 120-cfm unit should be just enough for an average-size range. Figure up to 400 cfm for a wall unit and as high as 600 cfm for an island cooktop.
