Island hoods are the biggest of the cooker hoods available and the most expensive. Island hoods attach directly to the ceiling so you’ll need a big kitchen with a lot of space to accommodate an island hood. Most cooker hoods come with two or more halogen or incandescent lights to illuminate your cooking. Cooker hoods can be set up to extract air through a duct to a vent in your wall or to pass extracted air through carbon filters before re-circulating back into your kitchen. We test all cooker hoods in extraction mode which is the most effective way of removing steam and smells.
