For technical or ecological reasons a cookerhood with an external extraction isn’t always possible. (ex. buildings with a central ventilation, system D ventilation). In this case a Novy cooker hood with recirculation is the best solution.
A recirculation hood filters the fumes that come from cooking and brings them back in the room.
The fumes are filtered from grease and odours with active charcoal (Monoblock filter). The humid air that comes out of the hood will be balanced by the ventilation system.
