The TruSteam range hood is packed with innovative technology and unmatched features. At the touch of a button, TruSteam effortlessly self-cleans the hood interior by spraying high-temperature steam (130℃ / 266℉) onto the fan blades and interior housing followed by a hot water rinse. This process efficiently removes grease, germs, and odors without any harsh chemicals or scrubbing. In addition, our newly developed whisper-quiet motor increases the ventilation performance while operating at nearly inaudible levels at working speeds.TruSteam's unique whisper-quiet motor is paired with larger fan blades and a high-capacity housing design to provide unprecedented ventilation. Backed by cutting-edge research, the TruSteam is the most powerful range hood available in the US (along with our Auto Clean model) with a CFM of 900+. That makes TruSteam especially suitable for high-fume, oil-based cooking, as is common with Chinese, Indian, Southeast Asian, and other popular cuisines.
