Description & Features
The BROAN ALT2303SS under‑cabinet range hood brings powerful, quiet ventilation and a sleek, modern look to any 30‑inch cooking surface. Designed for homeowners who want professional‑style performance without overwhelming noise, this stainless steel hood delivers up to 350 Max blower CFM to quickly clear smoke, steam and lingering cooking odors, while its advanced capture design helps keep the air in your kitchen fresher and more comfortable. At just 1.5 sones on working speed, it operates at a sound level comparable to a running refrigerator, so conversations, music and family time can continue uninterrupted even when the fan is on. With a width of 30 inches, it fits perfectly over most standard ranges and cooktops, making it an easy upgrade for both remodels and new installations.

One of the standout advantages of the ALT2303SS is its combination of high efficiency and low noise, a balance many competing hoods struggle to achieve. The hood is engineered to be more effective at removing airborne pollutants than many similar models in its class, yet it remains impressively quiet, making it ideal for open‑concept spaces or busy family kitchens. Another premium feature is the bright, two‑level integrated LED lighting that evenly illuminates your cooking surface while using far less energy and generating less heat than traditional bulbs. These long‑lasting LED modules are designed to withstand the heat from everyday cooking, so you get clear visibility for everything from simmering sauces to searing steaks.

Ease of use and maintenance are also central to this model’s appeal. Intuitive tap‑touch controls give you three fan speeds and two lighting levels at your fingertips, with a smooth, easy‑to‑wipe control surface that complements the clean lines of the hood. Beneath the hood, fully enclosed, dishwasher‑safe micro‑mesh filters capture grease efficiently and can be removed in seconds for quick cleaning, helping maintain strong airflow and a cleaner kitchen environment over time. Installation is simplified with a design that supports both top or rear venting, as well as non‑ducted recirculating setups when used with the appropriate charcoal filters, giving you flexibility no matter how your kitchen is configured. Blending performance, quiet operation and modern styling, the BROAN ALT2303SS is a smart, long‑term ventilation solution for everyday home cooking.

Hardwire or plug‑in installation – can be direct‑wired or used with an optional power cord kit (model HCK44, sold separately) for outlet connection.
