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 Aluminum

Mesh Filter set. Order according to its Part number below. The standard Aluminum Mesh Filters are intended

to capture residue from cooking and the optional charcoal ﬁ lters help to purify fumes exhausted from cooking

for re-circulation.
