Whether the air conditioner is running or the furnace is on, it seems like the air in your home is always dry. Add some moisture to the air you breathe with the TotalComfort® Cool Mist Ultrasonic Humidifier. With up to 25 hours of runtime, an auto-off timer (so you can set it and forget it), and 2 mist output settings, you'll be breathing easy again in no time. The TotalComfort® Humidifier is whisper-quiet for nighttime use, and the nightlight features 7 colors, so you can light up your room however you want. Clean Tank Technology helps protect the tank from mold and mildew, and a demineralization cartridge helps prevent white buildup on your walls from hard water. You can even add your favorite essential oils to the essential oil tray for an even more-relaxing experience.
