Ductless 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 exhaust
from cooking are drawn and fi ltered by a set of optional charcoal fi lters. The air is then purifi ed and re-
circulated back within the home.
We recommend to ALWAYS exhaust air outside of the home by employing existing or installing new duct
work, if possible. The hood is most effective and effi cient as an exhaust hood. Only when the exhaust option
is not possible should you recourse to converting the hood into a recirculating hood.
When converted to be a recirculating hood, a set of charcoal fi lters are required on top of its standard Metal
Filter set. Order according to its Part number below. The standard Metal Filters are intended to capture
residue from cooking and the optional charcoal fi lters help to purify fumes exhausted from cooking for re-
circulation.
