Broan-NuTone F402423 Exhaust Fan for Under Cabinet Two-Speed Four-Way Convertible Range Hood Insert with Light, 24-Inch, Black

The Broan-NuTone F402423 Under-Cabinet Range Hood Insert provides dual-function ventilation and lighting for 24-inch cooking spaces. Installed directly beneath your kitchen cabinetry at least 18 inches above the cooktop, it combines an exhaust fan with an overhead light fixture to manage steam, grease, and cooking odors during everyday meal preparation.

At maximum setting, the fan delivers up to 230 CFM of airflow with a sound rating of 6.5 Sones, giving you two speed levels managed via a front-mounted rocker switch. The ventilation system is HVI 2100 certified to verify its performance metrics. For lighting, an integrated fixture equipped with a protective lens accommodates up to a 75W incandescent bulb, controlled by its own independent rocker switch so you can run the light without turning on the exhaust fan.

Flexibility is a central feature of this model thanks to its four-way convertible layout. You can install it using a 3.25-inch by 10-inch vertical or horizontal duct setup using the included damper and adapter, set it up with 7-inch round vertical ducting using the included adapter, or configure it as a non-ducted unit that recirculates air back into the room. Maintenance involves removing the one-piece aluminum grease filter and running it through a standard dishwasher cycle.

Buyers should note that several setup components are sold separately depending on how you install it. The light bulb is not included, nor is the power adapter or the separate filter required for non-ducted recirculation. Additionally, while the 3.25-inch by 10-inch damper is supplied, a damper for 7-inch round ducting must be purchased separately if that configuration is chosen.

Verdict: The Broan-NuTone F402423 is a practical, adaptable ventilation choice for homes requiring a 24-inch under-cabinet range hood. Its four installation modes and dishwasher-safe filter make it a dependable fit for cooks looking for straightforward speed and light controls without unnecessary complexity.

A great fit if you:

• Need a 24-inch under-cabinet range hood insert that installs at least 18 inches above your cooktop surface.
• Want versatile installation options that can adapt to vertical ducting, horizontal ducting, or non-ducted recirculation.
• Prefer a simple grease filter that can be popped into the dishwasher for routine cleaning.
• Require a range hood insert that can be integrated into an ADA-compliant system layout.

Consider something else if you:

• Prefer an insert with an included LED light bulb rather than supplying your own incandescent bulb up to 75W.
• Want a complete package out of the box without needing to buy a power adapter or recirculation filter separately.

Confirm on the listing:

• Measure your cabinet space to confirm a 24-inch width fits properly and allows at least 18 inches of clearance above your cooktop.
• Check which installation parts you need to order separately, such as the power adapter, a 75W incandescent bulb, or a recirculation filter for non-ducted setups.
• Verify your ductwork dimensions to see whether you will use the included 3.25-inch by 10-inch damper/adapter or the included 7-inch round adapter.
• Confirm whether your installation requires a separate damper if you plan to use 7-inch round vertical ducting.

How to compare your options: Focus on airflow performance, sound ratings, and ducting flexibility when choosing a range hood. Compare maximum CFM ratings and Sone levels to ensure the unit matches your cooking habits. If your kitchen layout restricts ducting choices, a 4-way convertible design provides the versatility to switch between vertical, horizontal, or non-ducted operation.

If you choose ductless installation, ensure you purchase and install the compatible recirculation filter before operating the hood. Place your preferred incandescent bulb, up to 75 watts, behind the protective lens prior to securing the unit underneath your cabinet.

Position the unit at least 18 inches above your cooktop during installation to maintain safe clearance and optimal grease capture. Use the lower fan speed for light simmer work and switch to the higher speed when cooking with higher smoke or grease production.

Remove the one-piece aluminum grease filter regularly and wash it in your dishwasher to keep airflow smooth and maintain capture efficiency over time. Wipe down the black exterior casing according to standard appliance care habits using mild soap and a soft cloth.
