Turn on the hood one minute before you start cooking to create a stream of air to convey fumes and vapors to the extraction area.
Low speeds are generally sufficient for weak cooking fumes and odors, such as when cooking pasta and sauces.
High speeds are needed for cooking that emits strong odors and fumes, such as frying, grilling or cooking several dishes
simultaneously.
Leave, if needed, the hood on even after cooking in order to ensure all the fumes and odors have been extracted.
