AOS U200 Cool Mist Ultrasonic

Humidification System

This efficient ultrasonic system uses high-frequency vibrations to turn water into a micro-fine mist, which is then blown into the room where it evaporates immediately. The AOS U200 consumes very little power, and a replaceable demineralization cartridge ensures water mist without lime scale or mineral residues. A built-in output regulator ensures that every Ultrasonic unit properly humidifies the room in which it is used.

Comfort and Climate

  • Humidifies the air in rooms up to 430 sq ft
  • Powerful and replaceable Demineralization Cartridge

Water and Hygiene

  • The Hydro Cell uses activated carbon technology to help reduce heavy metals, impurities and odor causing chemicals that may be present in your household tap water. Activated as soon as it comes into contact with water, this advanced water maintenance system keeps AIR-O-SWISS humidifiers operating at its highest level between recommended cleanings.+ 
  • 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
    • + refer to the user manual which accompanies the AIR-O-SWISS humidifier for proper cleaning instructions
