People are usually confident in what they want in terms of the looks and style for their kitchen range hood. The harder part in buying a range hood forming an understanding of all the different components and how they work together to provide the best air ventilation possible. The factors you have to consider are many, including the amount of cooking you do, the space you have, the type of range you have and where the range hood will be mounted in the kitchen. You will also have to determine the size of the range hood you need and the capture area.
The size of your range hood will not be the only determining factor in the air ventilation you get with your unit. The size of the range hood works together with the fan, the vent size, the speed levels, the CFM and the range hood height to trap air and ventilate it to the outside of the house. However, there are some simple rules of thumb you can follow while choosing the size of your range hood, which will affect the capture area. The range hood has to be large enough to capture the grease, smoke and smells that travel upward during cooking.
First, the range hood should always be as wide as the cooking surface with an additional three inches on each side if possible. Secondly, you want the range hood to be as deep as the cooking surface. The range hood should cover at least the back burners on the cooking surface and half of the front burners. This is especially true when purchasing island range hoods, which have to work harder to compete with cross currents of air because they are not mounted against a wall. Island range hoods are mounted from the ceiling and hang over the cooking surface on a kitchen island. Island range hood also require larger capture areas for this reason.
Additionally, the further away the range hood is from the range, you will need more power and more capture area to compensate for the distance from the cooking surface. The distance between the range hood and the cooking surface is known as range hood height; manufacturers include recommended range hood heights for particular mounting styles and designs. If you choose to mount the range hood higher than these recommended heights, you may need a model with more power and capture area to ensure good ventilation.
Sometimes a larger range hood is recommended in kitchens in which a lot of cooking and a lot of cooking at high temperatures is done on a regular basis. Also, professional range hoods, which usually perform at higher CFM, may need to be larger because they are moving larger amounts of air. CFM stands for cubic feet per minute and describes the volume of air the range hood is capable of moving.
