Overview

Firegas's 36 inch under-cabinet range hood runs ducted or ductless with a 300 CFM 3-speed fan, aluminum and charcoal filters, LED lighting and button controls.

This is a budget-tier hood, and reviewers treat it that way: easy to install, a clear look upgrade over what it replaced, but with a couple of design shortcuts worth knowing before mounting it. Several owners flag a flap lever that doesn't fully seal when venting outward, letting some air slip back into the room unless it's taped shut. One long-term owner also reported the control board failing around seven months after installation.

  • 300 CFM 3-speed exhaust fan
  • 35.24 x 18.9 x 5.3 inch under-cabinet footprint
  • 3-layer aluminum grease filters
  • 1 year limited warranty

Who it's for

Works for kitchen remodels needing a 36 inch under-cabinet hood in either a ducted or recirculating setup. Not the choice for anyone expecting whisper-quiet operation or guaranteed long-term reliability.

What buyers say

From Amazon customer reviews.

Buyers repeatedly describe the install as easy and the look as a clear upgrade over what they replaced, with several praising the LED lighting over old halogen bulbs. The recurring complaints are a vent flap that doesn't fully seal against backflow when ducted, a charcoal filter some feel is mostly empty space, and, from one longer-term owner, a control board failure about seven months after installation.
