- Exhaust hood: the intake air is exhausted to the outside.
- Recirculation hood: the air is filtered before being returned to the kitchen.
Some ranges offer both modes of operation. In addition to its practicality, the filter unit or hood can also become a real design object that gives cachet to a kitchen.

Look for the Home Ventilating Institute (HVI) seal, which guarantees that the airflow (CFM) and noise levels specified by the manufacturer have been rigorously tested by an independent laboratory.
