A ductless or ventless range hood is simply a recirculating type range hood. Instead of ducting or venting the exhaust air to the outside world, a ductless range hood extracts the steam from your cooktop and passes it through some metal filters (to trap the cooking grease) and then recirculates the cooking air back into your room.

Some ductless range hoods have an additional charcoal filter installed. The purpose of this filter is to eliminate cooking smells from recirculating back into the room. Charcoal filters usually have a life span of approximately 3 months and they must be discarded and replaced with new charcoal filters. They cannot be cleaned and re-used.

Ideally you should try to duct or vent your range externally. Some times it is just not possible to do this and this is where a ductless or ventless rangehood is most appropriate.
