This range hood uses a double tunnel design to extract fumes and vapor. The tunnel below extracts most of the smoke before it diffuses while the upper one easily deals with the rest. Together, they guarantee a clear and clean cooking environment. The smart smoke-detection technology allows users to focus on cooking without having to worry about operating the range hood. The hob is equipped with temperature sensors located below the gas vents which automatically adjusts the intensity of flame to the user's needs and advises on specific cooking steps.
