Product Description:
The Air-O-Swiss Ultrasonic Warm Mist Humidifier uses high-frequency vibration to generate a micro-fine mist. It 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 before it enters the nebulizer chamber. The mist exits the humidifier at a comfortable 104°F, so the mist does not cause room temperature to fall. Pre-heating also keeps the water cleaner. The Air-O-Swiss Ultrasonic Warm Mist Humidifier also features Automatic and Sleep modes. Automatic mode maintains ideal humidity you select in relation to room temperature. When the Sleep mode is set, the unit shuts off after eight hours.

My 89 y.o. Dad suffers from Parkinsons. Since he doesn't swallow as often as non afflicted he is tormented with a phlegm build up during the night. This warm mist vaporizer made a significant improvement in his breathing comfort as well as speaking ability. It is absolutely silent and maintains the desired humidity levels. Since we have an undercounter filtration system we do fill it with filtered water and I would recommend that for any machine designed to process water. We are very pleased.
