Overview
The Zephyr Monsoon Mini II is a 42 inch convertible insert range hood rated 600 CFM, built to mount inside a custom hood liner or enclosure rather than stand alone. LED lighting and a stainless steel finish match the rest of the Zephyr range hood lineup.
As an insert, this unit is meant to be hidden inside custom cabinetry or a decorative liner rather than shown as the finished hood itself, which is a different installation than the ducted under-cabinet hoods Zephyr also sells. Convertible venting means it can run ducted to the outside or in recirculating mode depending on the kitchen setup.
- 42 inch insert width
- 600 CFM rated airflow
- Convertible ducted or recirculating venting
- LED lighting, stainless steel
Who it's for
Fits a kitchen where a custom wood or metal hood enclosure is being built and needs an insert blower behind it. Not the choice if you want a hood that is finished and ready to mount on its own, since this is designed to disappear inside other cabinetry.
Strengths and trade-offs
Drawn from this product's published specifications.
- 600 CFM rated output
- 42 inch width for larger cooktops
- Convertible between ducted and recirculating venting
- LED lighting included
- Requires a separate hood enclosure or liner to install
- Single customer rating available at time of writing
Performance notes
The 600 CFM rating applies in ducted mode; recirculating mode filters and returns air to the room instead of venting outside, which is typically the lower-performing of the two options on convertible inserts generally.
