Full List

The Air-O-Swiss Travel Ultrasonic Cool Mist Humidifier 7146 features a compact portable unit that is perfect to take and use anywhere. Made with the same high quality efficiency as the Air-O-Swiss full-size models, it uses high-frequency ultrasonic vibrations to generate a micro-fine cool mist that is then blown into the room. It comes with a soft carry bag and a transcontinental travel AC adapter and exchangeable plugs, so you can take it anywhere in North America or Europe. Just add your own half-liter water bottle and plug it in!

The bottle neck adapter has two size fittings, but be aware that it is not a screw on adapter; rather, it fits into the inside of the bottle mouth, so insertion and removal is extremely tight. So to avoid collapsing the bottle’s wall from the pressure applied while inserting it onto the humidifier, try using thicker walled plastic bottles, especially if you’re going with a larger-sized bottle. The unit comes with pullout, stabilizing feet, but there is nothing to clamp the bottle onto the unit, so take care that it is not knocked off. As a result, glass bottles should not be used nor should it be left within reach of children. Of course, the tight fit of the bottle neck adapter ensures a water tight seal thus preventing leakage.

The AOS 7146 isn’t just for travel either – use it in your office at work, on your bedside table, on your desk, or anywhere you need quick and easy added moisture. Additionally, it’s incredibly easy to clean, especially if you use Air-O-Swiss’s EzCal. Just mix 3/4 teaspoon per 1/2 cup of hot water and let it sit in the unit for approximately 30 minutes. So not only is it easy to clean, but is also very easy to set up and use. And at only 1.3 pounds, it hardly adds any weight to your luggage at all!

One thing to keep in mind whenever using a humidifier is the type of tap water you have. Almost all humidifiers are tap water safe; however, the harder your tap water, the more white-dust buildup you will get in the room as well as inside the humidifier. If this happens, simply switch to filtered or distilled water.
