Broan 21" Range Hood Liner w SmartSense Auto Operation and Voice Control

Broan Elite® brings smart ventilation to your kitchen with this custom range hood insert featuring SmartSense® technology. Using infrared sensing, it automatically detects cooking heat and adjusts fan speed or turns on/off without your input—so you never have to think about ventilation again. Voice control integration with Alexa and Google Assistant lets you command your range hood hands-free: "Turn my range hood up to fan speed 3." Control it from anywhere through WiFi connectivity. Kitchens are the most polluted rooms in homes, filled with smoke, odors, and cooking chemicals. This HVI-certified insert delivers powerful 650 Max Blower CFM to remove pollutants and improve indoor air quality. Yet it operates whisper-quiet at just 0.5 sones on normal speed. The stainless steel liner protects cabinetry while maintaining a custom appearance. Dual-level heat-resistant LED lighting brightens your cooking space, and the 4-speed backlit soft-touch control is easy to clean. The EZ1 Installation System enables single-person setup for both professionals and DIY installers. Better air quality means better quality of life—Broan-NuTone's commitment to your home.
