AIR-O-SWISS U600 Ultrasonic Humidifier

As a sister model to the U650, the Air-O-Swiss U600 humidifier is an ideal solution to soothing the conditions caused by cool, dry winter air. The sleek, new U600 ultrasonic humidifier uses a titanium coated diaphragm to emit ultrasonic frequencies that safely and effectively change the water and disperse it into the air in any room in your home. With a built in hygrostat you can easily set a humidity level and a separate dial allows you to regulate the mist output. Together you have complete control over how and how quickly moisture is put back into the air inside your home.

As both a warm mist and cool mist humidifier, the AOS U600 can either be set to preheat the water to 176° F before it is turned into mist or simply used a room temperature. The preheat function help to control microbe growth while working to keep the temperature of your room steady. Three separate indicator lights allow you to quickly tell if the unit is on, if you have it preheating the water for a warm mist or if the tank needs to be refilled.

Like other Air-O-Swiss humidifiers, the U600 is one of the safest and most hygienic humidifiers available. With the Hydro Stick, a preheat feature and a demineralization cartridge this ultrasonic humidifier removes impurities from the water before they can be dispersed into the air. For nearly any room in your home, the Air-O-Swiss U600 is a great way to combat dry air safely and effectively!
