Humidifiers by Boneco (Air O Swiss) Model 7135 and 7142 use Ultrasonic fine mist with Silver Ion Technology. Dual use Cool or Warm mist.

The Boneco air humidification technology uses high-frequency vibration to generate a micro-fine mist. A fan blows the mist into the room where it immediately evaporates. Both the 7135 and 7142 Ultrasonic humidifier requires little power, has a built-in hygrostat and an output regulator button. A replaceable demineralization cartridge ensures a hygienic, pure water mist, without lime-scale or mineral residues. When operated with the pre-heating function, the water is heated to 176°F / 80°C before it enters the nebulizer chamber. The mist exits the appliance at a comfortable temperature of 104°F / 40°C. This has the advantage that the room temperature will not fall, and additionally the water can be kept cleaner.

These units can also operate using the Cool Mist option. A Silver Ion Stick keeps the unit's water germ free at all times inside the unit as well as emitting germ free water.
