5.0 out of 5 stars Excellent Portable Humidifer, October 13, 2009
This review is from: Air-O-Swiss AOS 7146 Travel Ultrasonic Humidifier - Cool Mist (Misc.)
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.

No, this unit does not need the silver stick like the large ones do-another fantastic reason to purchase this model; I use it in my room regularly, and it's working amazingly well so far! Not much energy and time is needed for maintenance either.

This thing is REALLY bright. Here is what harvard.edu says about light and sleep:
"Light at night is bad for your health, and exposure to blue light emitted by electronics and energy-efficient lightbulbs may be especially so.
Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted.

But we may be paying a price for basking in all that light. At night, light throws the body's biological clock-the circadian rhythm-out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.

But not all colors of light have the same effect. Blue wavelengths-which are beneficial during daylight hours because they boost attention, reaction times, and mood-seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown."

Mr. SkyRider, do you have prove of what you are saying about the light contributing to cancer, diabetes, heart disease and obesity? Is there an article that I can read on? Thank you.

Sky Rider,

Interesting article (ref. "Blue light has a dark side" May 1, 2012 for others who may be interested). Definitely good to know. One thing that wasn't clear in the article is how high the intensity of the blue light needs to be to have a discernible negative effect.

But, to your point, the humidifier blue light is pretty bright. And unfortunately, with the design of the humidifier, it's hard to block the light while keeping the humidifier functional, since the light emanates from the mist outlet, and any intervention may impede the mist release.

I think other contributors of the blue light would include late night iPad/Kindle reading (reportedly around 450 nm wavelength, which is in the blue range of 450-495 nm), tv, laptops, etc. which are likely common activities for travelers, and may be more impactful than the humidifier light.

More food for thought. Thanks again!
