Product Description

Now you can take AIR-O-SWISS quality with you wherever you go and enjoy healthy air anywhere! The Travel Ultrasonic AOS 7146 is compact enough to fit into your travel bag. Just add your own water bottle, plug the unit in and enjoy clean, moist air in your room. With the AOS 7146 you can ensure room humidity is just the way you like it. Efficient ultrasonic technology uses high-frequency vibrations to generate a micro-fine cool mist, which is blown into the room where it immediately evaporates.

Stay healthy and be more productive at work. Set the Travel Ultrasonic on your desk or in your office and enjoy clean, moist air throughout the day.

Thanks to the transcontinental AC adapter and exchangeable plugs the Travel Ultrasonic can be used throughout North America and Europe. The adapter means you can use your personal unit on both sides of the Atlantic.

Similar to all ultrasonic humidifiers, the AOS 7146 Travel Humidifier should be placed on a flat, stable surface at least 3 feet above the ground. Water bottles above the standard 16 FL OZ are not recommended due to the risk of overflowing of the unit. Please refer to the included instruction manual for more information. customer care : 800-336-0326

PROs: operates very quietly and very compact - great for travel and personal use by bedside at home. Bottle neck adapter has two (2) size fittings for use with standard plastic bottle. Adapter is very tight inside bottle's neck so water does not leak out. When turned upside down, metal ball stopper is water tight. Fold out 'feet' to mitigate tipping though it may not be sufficient to prevent tipping with larger bottles eg: one liter bottles. Has variable humidity adjustment which works reasonably well too.

CONs: bottle neck adapter fits into inside of bottle mouth - it is not a 'screw on' adapter. A positive about this is that it'll work with standard sized bottles (supports two sizes) however removal and insertion of adapter into bottle neck is VERY tight. Some plastic bottles are very thin walled. Press fitting the adapter can be problematic as bottle's wall may collapse from applied pressure during insertion. Therefore thicker walled plastic is recommended esp. if/when larger bottle is being used. Seniors with limited hand mobility may also find it difficult to manipulate due to tight fit. NOTE: though unit comes with stabilizing pullout feet, filled bottle is simply inserted into receptor - there is nothing to 'clamp' adapter and bottle to hold it in place ergo care should be taken as bottle can be knocked off unit easily. The water tight adapter will prevent the water escaping from the bottle however weight from falling bottle can/might cause damage to surrounding objects.

WARNing: Due to relative ease with which unit might tip, use of glass bottle is not recommended. Use in child's room may also not be recommended.

SUM: at price point and intended use, pros out weigh cons and therefore worthwhile purchase. Had adapter come with rubber 'O' rings for easier insertion and if adapter could have been clamped in more securely, it would have deserved 5 stars. CONs however only earns it 4 stars IMHO.

This unit is the original travel/portable humidifier. I shopped around and looked at the several imitators, but decided to go with the Air-O-Swiss name/reputation that I know and love.

This unit is tiny, and comes with a power adapter with both US and European plugs and a soft cloth carry bag.

I use it at McMurdo Station, Antarctica where the average humidity is in the single digits. It puts out less water than my full-size Air-O-Swiss unit at home, but a remarkable amount for a unit this size.

The blue light that others have complained about is fairly bright - as most blue LEDs are - but it's no brighter than most night-lights, and hasn't bothered my sleep. The blue light switches to a red light when the water runs out... kind of a nice heads-up feature if you don't have the output set high enough to see the "steam" coming from the spout.

Overall, I wouldn't hesitate to make this purchase again, and I'd replace this unit with the same if needed (unless or until Air-O-Swiss comes out with their own new replacement/upgrade). There are a couple other copies that are less expensive, but I haven't tried them - I went with the quality/service that I trusted at the cost of the higher price tag.

Out of the box this thing is very small. I actually bought it to replace my malfunctioning Air-O-Swiss 7135. (I also had just returned from a skiing trip where I had trouble sleeping due to the dry air in the hotel room.) I already had a small used water bottle, so I washed it well and filled it with water from my Brita pitcher. The insert that is supposed to fit tightly into the top of the bottle does fit well, and is not so difficult to insert as some here have said. Give it a slight twist as you insert or remove.

Upon operating, I see that it puts out quite a bit of water mist, and it is very quiet. I really can't imagine it being any more quiet. The only issue I confirmed that other reviews have said is that the tiny little LED bulb inside makes the unit glow very bright. I have uploaded some photos of the unit operating in a very dark room, and you can see that it lights up the corner of the room. If you have any issue with anything but near complete darkness when sleeping then this will surely be a problem. I fixed this by simply putting several coats of black acrylic paint on the bulb. I put up photos of a closeup of this as well. (Originally I planned on maybe taking the unit apart and just cutting the wires to the bulb, but there are no screws to be found on the outside.) So, the reason I didn't give this 5 stars is because I had to do this. There really should be an option to turn the light off. I understand that part of the reason it is there is because the light turns red when the water runs out. I really don't see that this is necessary for my use because I only run it for 6-8 hours overnight and running on high it still doesn't run out of water. I just fill it up each night before bed.

This review is for the Air-O-Swiss Portable Travel Humdifier (7146).

I bought this unit to help when I travel as I often have troubles with overly dry air. The unit comes with a nice felt carry bag, the nebulizer, the power supply, cleaning brush, and bottle adapter, all of which easily fit in the bag.

I have tried this unit out a few times, and it works well, but, you have to remember that it is a very small unit, and will not turn a large room into a steamy sauna. It is however enough to make a regular sized (300-400 sq foot) hotel room or office comfortable and "take the edge off." It will do about 500 mls in roughly 4-5 hours of time on full output.

It is very quiet, with more noise being made by the occasionaly "burp" of air into the bottle (kind of like a mini water dispenser) than anything else. The mist output is very fine, and evaporates rapidly into the air without leaving a soggy mess beneath it, (though I still wouldn't place it on any important papers).

Assembly is easy, plug the wall wart in to your power source, and then into the back of the unit and flip the legs out on the bottom. Get a small 500ml (17-20oz) water bottle, fill it with water, firmly push/twist the adapter into the open top, and then gently invert onto the unit, flip open the mist output, and turn it on. The output control knob is on the same side as the power cord, which is opposite the mist output.

There's no latches or anything to hold the bottle in place so make sure the unit is on something flat and stable. The adapter has a steel ball valve in it to keep the water from rushing out uncontrolled, but still allow it to "burp" as the unit needs more water.
