Air O Swiss 7146 Travel Ultrasonic HumidifierAir O Swiss 7146 Travel Ultrasonic Humidifier. Personal travel humidifier for healthy air on the go. Read the humidifier reviews. List price: $49.99. This compact travel humidifier can easily be taken anywhere to help humidify dry hotel rooms, the office or even travel internationally. It comes with a transcontinental adapter, which can be used in North America or Europe. Place your own water bottle on the humidifier and it’s ready.The big drawback is that it doesn’t come with an Air O Swiss demineralization cartridge, so white dust may accumulate. If you use reverse osmosis or distilled water in the humidifier, most of the time it will not produce the white mineral dust. There is mist output control. It is very quiet to operate and weighs around one pound. Air O Swiss Ultrasonic Travel Humidifier Consumer Reviews Reviews from users on this travel humidifier are positive with a four star average. Benefits are the small travel size and being able to relieve the red eyes and dry nose from dry air.The drawbacks are the bright blue light that shines when it is on. Too bright for some. I like to put tape over the humidifier light and cover the tape with a black marker to dim the light. Overall it is a good personal travel humidifier for healthy air while traveling.
