Introducing the EVDC500 our new whole-room two-tank evaporative humidifier with an Energy Smart DC motor. With more power than a standard Vornado it delivers our whole-room humidity circulation using 90% less energy. Pressing the leaf button saves even more energy automatically turning off if it runs out of water. The minimalistic design features clear easy-fill 1-gallon tanks that are simple to use and maintain with a low-water indicator that shows when its 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 EVDC500 ensures a comfortable breathing environment with the peace of mind of a 5-year satisfaction guarantee and 10-year motor warranty.
