Alta 30-Inch 490 MAX Blower CFM 1.1 Sones Stainless Steel Range Hood
From the leader in residential indoor air quality, this under-cabinet range hood by Broan-NuTone is built to surpass industry standards with over 50 points of inspection, engineered as a reliable ventilation solution. The durable hood vent is equipped with SmartSense Auto Operation that automatically monitors and adjusts the ventilation power needed based on heat coming off the cooktop to maitain the intregity of the IAQ in your space. The Alta range hood is also up to 71% quieter: 1.1 sone is equivalent to a refrigerator running, so it won't interfere with daily life. The EZ1 Install System allows for a quick and easy 1-person installation, and the ENERGY STAR Certification is both code compliant and provides cost savings. Code Ready Technology (CRT) provides capability to reduce the 490 Max Blower CFM down to 300 or 400 CFM to meet local code requirements, and the 2-Level LED lighting modules and a 3-Speed whisper touch infrared control make cooking a breeze. At Broan-NuTone we believe that better quality of air means better quality of life.
