What is the difference between a range hood and an exhaust fan?
Similarly, it is asked, do you really need a range hood?
Most residential building codes do not require a range hood above a stove or cook top, but you'd be wise to ensure your locale is not the exception. Even if it's not legally required, you should think long and hard before forgoing a hood altogether.
Also, what kind of range hood do I need?
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 between 20 and 24 inches away from an electric cooktop and 24 to 30 inches from a gas cooktop.
