Introducing Zephyr's recirculating kit for the 36-in. Roma Island Hood. This kit allows for no external venting by filtering air through a charcoal filtration system directly back into the kitchen. It makes maintaining temperatures and humidity easier! Designed to be used with The Monsoon Mini Collection of range hood inserts, this kit eliminates the need for vent pipe or any sort of complex ventilation system. Above all, this kit is quick and easy to install!
