Welcome to the age where a humidifier can inspire, mesmerize, and illuminate. The Lucerna 3 Ultrasonic Humidifier is the flagship of the Vornado Alchemy line that stands in at a formidable 18” tall and brings with it a 1.5 gallon tank capacity. Its dual fan design ensures that humidity is distributed evenly throughout the whole room while the ribbed tank creates a mesmerizing effect as ambient light is refracted through all the slices up and down the exterior – with or without the humidifier running. With up to 24 hours of runtime on low (12 hours on high) the Lucerna 3 has the endurance to maintain comfort all day. LUCERNA – Humidification doesn’t have to be humble.
