Overview
Kitchen remodelers building a custom wood or plaster hood get the working insert that goes inside it. The blower exhausts through a round duct, baffle filters catch grease, and LEDs light the cooktop.
Reusable filters and a plug in power cord keep upkeep and wiring simple. As an insert it only works inside an enclosure you build, and quiet operation depends on fitting rigid ducting, which is sold separately.
Who it's for
Homeowners building a decorative hood cover who need the fan, lights and filters inside it. Kitchens with no way to duct outside should look at a recirculating model.
Pros and cons
- Baffle filters go in the dishwasher
- Plug in power, no hardwiring
- Backdraft damper included
- Flexible ducting in the box
- Needs a custom enclosure
- Rigid duct sold separately
- No recirculating option listed
Performance notes
Capture depends on fan speed and duct path: a short, rigid duct run moves air freely, while flexible duct adds resistance and noise. Baffle filters trap grease in their folds and wash clean rather than needing replacement.
