13Ductless recirculation is intended for applications where an exhaust duct work is not possible to be installed.When converted, the hood functions as a recirculating hood rather than an exhaust hood. Fumes and exhaustfrom cooking are drawn and filtered by an optional charcoal filter. The air is then purified and recirculated backwithin the home.We recommend to ALWAYS exhaust air outside of the home by employing existing or installing new ductwork, if possible. The hood is most effective and efficient as an exhaust hood. Only when the exhaust optionis not possible should you recourse to converting the hood into a recirculating hood.When converted to be a recirculating hood, a charcoal filter is required on top of the decorative mesh filter.Order according to its part number below.
