Product Description

The ultra-quiet Air-O-Swiss AOS U650 Digital Warm & Cool Mist Ultrasonic Humidifier, for rooms up to 650 sq. ft., combines all the features of the AOS U650 with digital display and surface-touch controls, intelligent automatic humidification regulator, sleep mode and timer.

The Air-O-Swiss AOS U650 Warm & Cool Mist Ultrasonic Humidifier uses high-frequency vibrations to turn water into your choice of cool or warm micro-fine mist. The replaceable demineralization cartridge ensures water mist without lime scale or mineral residues, and the included Hydro Stick keeps the humidifier clean and fresh longer.

Comfort and Climate

  • Humidifies the air in rooms up to 650 sq. ft.

Quad-band Water Quality Protection

  • The Hydro Stick provides constant freshness in Air-O-Swiss humidifiers. This advanced water maintenance system keeps your humidifier operating at its highest level between recommended cleanings. Good for one year, the Hydro Stick ensures your humidifier's functionality while providing fresh humidification performance.
  • Ultrasonic system, with its high-frequency vibrations, destroys most microbes
  • Pre-heating the water to 176 °F (80 °C) inhibits growth of microbes (when using warm mist option)
  • Plastic housing of the demineralization cartridge is treated with silver (Ag+ Ionic Silver Technology) inhibiting microbial growth on its surface
