• SmartSense™ Automated Ventilation – uses an infrared sensor to detect heat from the cooktop and automatically adjusts fan speed to clear smoke and cooking odors with no manual effort.

• EZ1™ Install System one‑person installation – includes EZ1 mounting brackets so a single installer can securely mount the hood in roughly half the usual time.

• Code Ready Technology (CRT) – allows airflow to be reduced from 490 Max Blower CFM down to 300 or 400 CFM to meet local building codes or make‑up air requirements.

• ENERGY STAR® certified performance – meets strict energy‑efficiency standards to help reduce operating costs while maintaining strong ventilation.

• Title 24 compliant design – satisfies California Title 24 energy code requirements for residential ventilation when properly installed.

• Alta series under‑cabinet range hood – premium Broan‑NuTone Alta design that fits neatly under standard 30" cabinets for a built‑in, modern look.

• 490 Max Blower CFM ventilation – provides powerful airflow to quickly capture and exhaust smoke, steam, and airborne grease from everyday cooking.

• Up to 71% quieter operation – runs at just 1.1 sones on working speed, about as quiet as a running refrigerator, to minimize kitchen noise.

• 3‑speed whisper‑touch infrared controls – lets you manually select three blower speeds and two light levels with smooth, easy‑to‑clean touch controls.

• Bright 2‑level LED lighting – integrated, heat‑resistant LED modules offer high and low settings to clearly illuminate the cooktop.

• Hybrid baffle filters – high‑efficiency hybrid baffle filters capture grease effectively while allowing strong airflow.

• Dishwasher‑safe filters – removable hybrid baffle filters can be placed directly in the dishwasher for quick, hassle‑free cleaning.

• Fully enclosed bottom design – smooth underside surface helps contain grease, simplifies wipe‑down, and gives a clean, finished appearance.

• Convertible ducted or non‑ducted installation – supports top or rear ducted venting, or recirculating (non‑ducted) operation when used with optional charcoal filters.

• Optional charcoal recirculation filters (HPF30) – enable non‑ducted installation by filtering and returning air back into the kitchen when exterior venting isn’t possible.

• Under‑cabinet 30" width – sized to fit most 30‑inch cooktops and ranges, ideal for standard kitchen layouts.

• Low‑profile 5" height – slim body design maximizes headroom and maintains a sleek, unobtrusive look under cabinets.

• Stainless steel construction – durable stainless steel finish resists corrosion and staining while complementing modern appliances.

• Top or rear discharge options – supports multiple duct configurations to match existing venting (vertical or horizontal) and simplify replacement installs.

• Hardwire or plug‑in flexibility – can be hardwired directly or connected using an optional power cord kit (model HCK44, sold separately).

• Optional Universal make‑up air damper compatibility – works with optional MD6TU, MD8TU, or MD10TU dampers to bring in fresh air only when the hood is on, helping balance household air pressure.

• ADA‑compliant capable installation – can be configured for ADA compliance when used with the optional HAWRK5 low‑voltage wiring and wall‑switch kit.

• HVI‑certified performance – tested and certified by the Home Ventilating Institute for verified airflow and sound ratings.

• 50‑point inspection quality control – each unit undergoes extensive factory inspection to ensure long‑term reliability and consistent performance.

• Improved indoor air quality (IAQ) – continuous and automatic ventilation features help reduce airborne pollutants, moisture, and odors in the kitchen.

• Grease and odor reduction – strong capture area and efficient filtration help keep cabinets, walls, and ceilings cleaner over time.

• Energy‑saving operation – efficient motor and LED lighting reduce electricity use compared with traditional hoods and incandescent bulbs.

• 1‑year parts warranty coverage – provides manufacturer support and protection against defects in materials and workmanship.
