Downdraft hoods are usually built into an island or peninsular unit behind the hob and when switched on it rises electronically from the work surface. It works by pulling the steam and odours from the cooking area and pushing them through the grease filters and down below the work surface to the outside wall through ducting. Alternatively if you’re recirculating the air using optional charcoal filters you would normally fit a ventilation grille in the plinth to allow the warm air to escape. Some models are designed to be flush fitted into a solid worktop such as granite or quartz for a perfectly seamless look. Check out our wide selection of downdraft hoods below, made up of fantastic models from the likes of market-leading brands like CDA, Siemens, AEG and Neff.
