Excellent Portable Humidifer
By Scott Mosher
This unit is the primary travel/portable humidifier. I shopped around and looked at the assorted imitators, but decisive to go with the Air-O-Swiss name/reputation that I recognise 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 intermediate 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 when it comes to is somewhat bright - as most blue LEDs are - but it's no more glorious 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 sufficient to see the "steam" coming from the spout.

Overall, I wouldn't hesitate to make this buy again, and I'd replace this unit with the same if necessitated (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.

quiet and compact
By A. Horvath
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 popular 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 altho it may not be sufficient to prevent tipping with larger bottles eg: one liter bottles. Has variable humidity adjustment which works somewhat well too.

CONs: bottle neck adapter fits into inside of bottle mouth - it is not a 'screw on' adapter. A positive regarding this is that it'll work with ordinary sized bottles (supports two sizes) notwithstanding remotion and insertion of adapter into bottle neck is VERY tight. Some plastic bottles are very thin walled. Press fitting the adapter may be problematic as bottle's wall may collapse from used pressure for the duration of insertion. Therefore thicker walled plastic is commended esp. if/when more spectacular bottle is being used. Seniors with fixed hand mobility may likewise find it difficult to manipulate due to tight fit. NOTE: altho unit comes with stabilizing pullout feet, filled bottle is plainly inserted into receptor - there is not one thing to 'clamp' adapter and bottle to hold it in place ergo care ought to be taken as bottle may be knocked off unit easily. The water tight adapter will prevent the water escaping from the bottle nonetheless weight from falling bottle can/might cause harm 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, masters out weigh cons and consequently suitable purchase. Had adapter come with rubber 'O' rings for posing no difficulty insertion and if adapter could have been clamped in more securely, it would have deserved 5 stars. CONs nonetheless only earns it 4 stars IMHO.

The Perfect Accessory for Trips to Phoenix or Riyadh
By J. Savani
After my government issued ID and money, this astounding gadget is the third key thing I would take on a trip to a arid place. After three miserable trips to Phoenix where my eyes were arid and red and I felt tired and miserable, I brought this portable humidifier for the fourth trip (in as some months). What a divergence it makes to sleep with the thing lacing the air with balmy droplets of water. I wish I had had it on other trips to other arid places (including, incidentally, Beijing), but also the numerous arid places in the Middle East, such as Riyadh. I also plan on taking it to any place cold sufficient to require forced air heating in winter. I in truth like shoes, but will leave a pair behind to accommodate this humidifier in my standard supplement of carry-on baggage. It's that good!
