Moffat MH65B is a cooker hood designed to be operated by adults. It can be used to duct odors to the outside or to filter the air within the kitchen. If used to filter the air within the kitchen, a charcoal filter will be required. The hood is convertible to either function by the movement of a slide control, thus enabling the hood when installed in the ducting mode (extraction) to be converted to filtered (recirculation) in one easy step.
