Product Description

Compare Boneco / Air-O-Swiss Humidifiers

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

The Boneco / 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 Cell keeps the humidifier clean and fresh longer.

Special Features

  • State-of-the-art design with surface touch controls
  • Night-time display dimmer for a restful sleep
  • ITC™ technology (Intelligent Temperature Compensation) automatically regulates the output to create the most comfortable relative humidity adjusted to the temperature in your room
  • Sleep mode: the unit pre-determines a comfortable night humidity level, the display brightness is automatically dimmed
  • Timer allows for 1 to 8 hours or continuous operation
  • Transparent water tank
  • Industrial strength titanium membrane surface, for fast dispersion of mist into the air and long lasting use
  • Empty and cleaning indicators

Comfort and Climate

  • Humidifies the air in rooms up to 650 sq. ft.
  • Choice of cool or warm mist humidification.
  • Warm mist heats water to 104°F so ambient room temperature is not cooled
  • Powerful and replaceable demineralization cartridge with silver treated housing

Quad-band Water Quality Protection

  • The Hydro Cell 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 three months, the Hydro Cell 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

Energy and Performance

  • Built-in hygrostat for controlled humidification
  • Variable mist output control
  • Very energy-efficient
  • Ultra-quiet operation
Replace the Boneco / Air-O-Swiss Hydro Cell every 1 to 3 months depending on water hardness. Install a new mineral cartridge or refill the granules every 2 to 3 months of use. Use the  Boneco / Air-O-Swiss EZCal solution to descale the water base once every 2 to 3 weeks.
