The included Hydro Cell keeps the water in the tank clean and fresh. The U650 ultrasonic humidifier is effective in areas up to 650 square feet.

Features of the BONECO U650 Ultrasonic Cool and Warm Mist Humidifier

  • ITC™ Technology (Intelligent Temperature Compensation) Automatically regulates the output to create the most comfortable relative humidity adjusted to the temperature in your room
  • Demineralization Cartridge (DMC) The plastic housing of the demineralization cartridge is treated with silver (Ag+ Ionic Silver Technology). This inhibits microbial growth on the surface of the cartridge to maximize filter life.

Activated as soon as it comes into contact with water, the Hydro Cell with activated carbon technology helps reduce heavy metals, impurities, odor causing chemicals and pesticides from your household tap water.
