Discover an easier, cleaner humidifier experience with the Clorox™ Ultra Clean Cool Mist Humidifier with UV LED Light. It stays cleaner longer with germ-reducing technology,* so you can focus on what matters most — keeping your air feeling moist and comfortable. When it's time to fill or clean the 4 liter (1 gallon) water tank, its large, top-fill opening provides easy access. The humidifier's mist output can be adjusted to 3 different levels from low to high, and if you want to direct mist precisely, the 360° directional mist output dial rotates as needed. You can easily increase your humidity to a target level with the auto mode, or set the 1-12 hour timer to fit your needs.
