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.

The Air-O-Swiss 7144 Ultrasonic Humidifier uses high-frequency vibrations to generate a microfine mist, preventing leaking and/or condensation on the unit. To avoid steam burn, you choose the pre-heating function and the mist then exits the machine at a pleasant 104 degrees Fahrenheit. A replaceable demineralization cartridge (Ag+ Ionic Silver Technology) ensures water mist without lime scale or mineral residues and a quad-band microbial protection system prevents microbial growth in the water base. To completely eliminate white dust buildup, though, it’s recommended to use reverse osmosis drinking water, which also has the added benefit of extending the life of the demineralization cartridge.

Most importantly, the Air-O-Swiss 7144 humidifier is equipped with ITC (Intelligent Temperature Compensation) technology that monitors the temperature to automatically adjust output when conditions change. In other words, this unit measures the humidity and turns on and off based on your chosen preset user selectable setting much like a thermostat does for heating and cooling.

One negative aspect to this unit is that the water tank is undersized and awkward to handle. Once removed, the odd shape makes it difficult to refill and prevent tipping. Additionally, it is nearly impossible to remove the tank without dripping water all over the floor because while installed in the unit, it actually sits in a pool of water; so just be sure to immediately wipe the base of the tank.

Although the tank is difficult to fill, it is equipped with a handle for easy carrying and a full tank will provide up to two night’s sleep free of irritating throat, nose, and skin conditions. Combined with it’s sleek, modern look and it’s state-of-the-art technology, the Air-O-Swiss 7144 Ultrasonic Humidifier is the perfect choice for someone serious about a good night’s sleep and maintaining a high quality of life.
