Overview
Under-cabinet ventilation is the job here: the Broan-NuTone Alta ALT2303SS is a 30 inch, ENERGY STAR certified range hood rated up to 350 max blower CFM with three-speed tap-touch controls.
The spec sheet leans on a 50-point inspection process and quiet operation at 1.5 sones on working speed, described as comparable to a refrigerator's hum. It installs with EZ1 brackets for a one-person setup and can vent out the top or rear, or run ductless with separately sold charcoal filters, which makes it workable in condos or units without outside venting.

Who it's for
Kitchens needing a 30 inch under-cabinet hood with flexible venting, including ductless installs where no outside vent exists, are the fit. Buyers who prefer simple rocker-switch controls over touch panels should weigh the review below first.
What buyers say
From Amazon customer reviews.
One buyer's lights failed out of the box, and they found replacement light modules run about 90 dollars each with a separate control board also at risk of failure, prompting a return in favor of a simpler rocker-switch model with fewer speeds but cheaper parts. Another buyer had the opposite experience, calling installation easy and the unit very quiet in a condo with no outdoor vent.
Strengths and trade-offs
Drawn from this product's published specifications.
- Easy one-person installation with EZ1 brackets
- Quiet at 1.5 sones on working speed
- Works ductless with charcoal filters where no vent exists
- Dishwasher-safe micro filters
- One buyer received a unit with non-functional LED lights
- Replacement light modules and control board reported as costly
Performance notes
The 350 max CFM blower and three-speed tap-touch control set the range of airflow available, while the 1.5-sone rating on working speed is what keeps it quiet enough that one buyer described installation and use in a condo without issue. Dishwasher-safe micro filters and an enclosed bottom are meant to simplify the grease cleanup that under-cabinet hoods usually require.
