Alno AEF3620N is a versatile kitchen hood that offers two operating modes: exhaust mode and filter mode. In exhaust mode, it efficiently removes vapors and odors by extracting them outside through an exhausting pipe. The filter mode, on the other hand, recirculates air through a carbon filter, which eliminates odors before releasing the air back into the kitchen. With its powerful motor and multiple speed settings, the Alno AEF3620N ensures effective odor and grease removal, creating a cleaner and fresher kitchen environment.
