Air-O-Swiss AOS 7146 Travel Ultrasonic Humidifier Review

Air-O-Swiss AOS 7146 Ultrasonic Humidifier Review: If you’re looking for a unit that you can use on the road, then you may want to take a look at the Air-O-Swiss AOS 7146 machine. It’s small enough to fit in your bag and is a great solution to add moisture to your room while away from home. For example, in your office or in your hotel room while on the road.

I don’t really have much of a need for it in my office, but it definitely comes in handy when traveling or on vacation. This portable humidifier is kind of similar to a portable air conditioner (or air cooler) but much more effective, in my opinion. It works very similarly to a regular humidification unit but doesn’t use as much power or take up as much space.


Air-O-Swiss Humidifier Review and product details it is a cool-mist ultrasonic machine that uses water bottles instead of a tank to operate. The preferred bottle size is 17 ounces (0.5 liters) and can mist up to 1 gal for every 24 hours that it is in use. Again, it’s a very small unit and doesn’t take up very much space. It also doesn’t use that much energy and operates very quietly as well.
Lastly, this unit comes with the appropriate AC adapters for North America and Europe and comes with its own travel bag. That way, you don’t have to worry about what to carry it in a while on the road.

WHAT did I like?

Air-O-Swiss Humidifier Review: The biggest benefit of this machine is that I’m able to humidify almost any room that I need to when I’m away from home. If I ever feel dry or even get sick on vacation, I can easily pull out my portable unit and start adding moisture to my room. Carrying around a regular humidifier unit on the road may not be conventional and could increase its risk of getting damaged. So having this option is great.

Another thing I liked about the Air-O-Swiss AOS 7146 Cool Mist Ultrasonic is how easy it is to clean and maintain. Since you don’t have to reuse the same bottle, you never have to clean the “tank.” That leaves you with cleaning the machine itself, which doesn’t take much time at all.

Last but not least, this unit comes with a blue night light, which could be annoying for some. However, I like how the blue light turns to red once your bottle has run out of water.


I wish I could change the minimum size of the bottle that’s allowed to be used with this machine. Seventeen ounces isn’t bad for traveling, I guess, but one liter would have been ideal, in my opinion. Another thing that kind of bothered me about this machine was its overall price. I did find the cost to be a little high, especially for its output capability. Although you have to consider, you’re not just paying for its functionality but also its portability benefits as well.


Air-O-Swiss Humidifier Review: In the end, if you travel a lot, especially during the winter, then you may run into a few hotel rooms with poor air quality. Having a compact humidifying solution can be very beneficial during those times and can play a big part in maintaining your health and providing a comfortable environment. Even if you don’t travel a lot and just want to add moisture to your office environment, then you can’t go wrong with this space-saving, ultra-quiet machine.
