If you're buying a new range hood and dealing with a pre-existing vent pipe, make sure that both connect easily. Range hoods will vent either through the cabinets above or through the wall. Make sure that a venting range hood will vent through the right spot in the wall.The most common sizes are 36in, 48in, and 60in. Make sure the range hood you are buying is the correct size that will fit.250 cfm is a respectable amount for an average-size kitchen, while 400 cfm is excellent. To find the right cfm rating for your kitchen, multiply the square footage of your kitchen by 2. A kitchen hood, extractor hood, range hood, or exhaust hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. The cfm rating represents how much air the vent can pull each minute, or cubic feet per minute. Buy a hood with the correct CFM rating. These hoods are typically used in commercial kitchens or above larger cooking ranges that create more smoke, odors, grease and fumes.If you can, purchase a range hood that extends at least one inch (2.5 cm) over all four sides of your cooking area.
