Will a fan over my range help remove moisture when I’m cooking?

Yes. Kitchen hoods installed directly over the range capture heated air, moisture, smoke, and odors, while a fan exhausts them through ductwork to the outside. An easily removed and cleaned filter traps grease. A kitchen range hood should be at least the same width as the cooking surface it will serve and be mounted directly over it at a height of 18 to 30 inches above the burners.
