Integrated cooker hoods are designed to fit snugly into integrated fitted kitchen units. They're not as powerful as chimney or island hoods and are suitable for use with a four-ring freestanding cooker or hob. Most cooker hoods come with two or more halogen or incandescent lights to illuminate your cooking. Most cooker hoods have two or three speeds and some come with a short high-power burst option to quickly clear a kitchen of steam and smells. Some hoods come with helpful indicator lights that tell you the speed the hood is operating at and when the grease filter is saturated.
