With 3 speed settings, this cooker is incredibly easy to control giving you the utmost versatility, as you can ensure that no matter what you are cooking, your kitchen will be smell and steam free. This Russell Hobbs cooker hood gives you the option to use ventilation via extraction or recirculation. Recirculation venting draws steams and smells into a filter which neutralises the odours, before being returned to the kitchen, whereas, extraction ventilation filters air with a grease trap before releasing it through an external vent (carbon filters must be purchased separately). Having both these styles of ventilation gives you increased versatility and ensures you can alter your cooker hood to best suit you, at the easy touch of a button.
