Ductless hoods can be installed almost anywhere. Since they don’t need to vent to your home’s exterior and are ductless. These hoods operate by filtering the air they suck in and then blowing it back out into the room, essentially using a recirculation process. The filter often contains activated carbon or charcoal which helps to remove odor and smoke particles from the air, which can then be cleanly recirculated back throughout the kitchen.

Of course, with the ductless model, it may be necessary to clean or change the activated charcoal filter about once or twice a year. This cleaning and replacement from time to time is necessary for your range hood to work most efficiently.
