The EVDC300 delivers whole-room humidification driven by an Energy Smart DC motor. With more power than a standard Vornado, it delivers our whole-room humidity circulation using 90% less energy versus a comparable Vornado AC motor-driven humidifier. The minimalistic design features a clear, easy-fill 1 Gal. tank that is simple to use and maintain, with a low-water indicator that shows when it's time to refill. Customizable humidity settings paired with precise auto humidity control allow you to tailor the natural evaporation process, leaving a perfectly humidified space free from the white dust that mist leaves behind. The EVDC300 ensures a comfortable breathing environment with the peace of mind of a 5-year satisfaction and 10-year motor.
