Range hoods are a necessity in any kitchen. They prevent pollution within the kitchen area by removing pollutants, odors and cooking smells. A properly installed kitchen range hood improves the cooking experience by venting hot air and cooking odors outside as well as help keep kitchen surfaces free of grease and fine particulate matter. They remove the heat that expands the air molecules and moves rapidly in all direction. Steam expands the water molecules to 1800 times and escapes carrying odours and grease which gets absorbed on walls, clothing and furnishing. Range hoods are perfect for keeping oil smells from permeating the air in your kitchen. They are especially handy when frying foods that require the use of vegetable oil or butter and in these cases are necessary to get rid of smoke and vapors. They are the principal focal points of the kitchen qnd can make a dramatic visual statement and complete your kitchen with a beautiful quality appearance.
A range hood is usually vented to the outside and remove grease, steam, and cooking odors from the kitchen. Some hoods do not have outside vents and rely on replaceable charcoal filters to clean smoke and odors from the air. They are available in different sizes and strengths, as well as noise levels. It may seem like bigger is better, but in the case of an exhaust hood, that is not necessarily so. Hoods are available in many sizes, but typically an up-draft range hood should provide 100 cfm of ventilation for wall-mounted hoods and 150 cfm for island hoods. They should always have a ducted passage to the outside that is fitted with a damper to prevent infiltration.
Range hoods are generally constructed to be 4 inches wider than your stove/cooking range. For example, a 36 inch stove would usually be complemented with a 40 inch range hood. They are often rated for sound and sound levels are measured in sones, which is different than dB ratings that vary exponentially. One sone is the sound of a new refrigerator cycling on.
Range hoods are a necessity for keeping good indoor air quality in the home, especially since some indoor pollutants can be measured at concentrations 50 times higher than outdoors. Hoods of all types protect the home’s occupants from poisonous gases, such as carbon monoxide, smoke and grease build-up, which can cause fires.
Stylish kitchen hoods are all the rage in the new and higher functioning kitchen. Sitting above a cooktop, hoods work to ventilate and redistribute the hot, often pungent air emitting from any number of cooking concoctions. They are often a code requirement, and should be placed directly over your cook top; they are not needed for wall ovens, which generally have their own vent systems. Other equipment in the kitchen such as washer dryer combo machines also need venting. Range hoods usually match the color of your oven and most range hoods have a fan and lighting inside.
