P.O.S., April 16, 2008
It works really well when it works. Sometimes it does sometimes it doesn't. It is like a Rolls Royce... it looks good, works well, but it needs a lot of care.
Worked Great ...for 2 months, March 30, 2008

This unit was great at the beginning, but after a month or so I noticed very little mist would come out at the center setting (as opposed to max). After 3 months it began working intermittently. Now it barely works. I can't open the inside to see if anything is dirty or something. Basically its junk now because I bought the unit at a local hardware store and just threw out the receipt about a week ago - after all - there is only one moving part - what could go wrong ?. I'll look for a different brand next time.

Seemingly great, BUT a big hidden problem!!!, March 14, 2008

I was very happy with this humidifier, quiet, low maintainence, and very effective. The problem started several months later. I found the CD player in the same room broken, and found lots of white dust inside it. The night light bulb was just covered with a thick layer of white dust. I am MOST CONCERNED about my toddler's health breathing air with so much white dust! Please don't buy this product for the health of your family!!

False advertising, January 6, 2008
I just received the product and have not used it, but I'm already dissatisfied. The ionic silver stick ($30 retail) which was supposed to come with the product was not there. Apparently they no longer include it, but didn't bother to say this anywhere. So the $110 item actually costs $140. I'm thinking about returning it.

I purchased this when I had a cold. I have always wanted a humidifier during winter time. It works great. No problems. It is a small pain to refill.

This site awards its highest rating to the almost-identical Air-O-Swiss 7135 (the 7133 lacks the 7135's digital display), with the editors commending its sleek design, virtually silent operation and ability to generate warm or cool mist. They also like the silver stick that prevents microbial growth and the demineralization cartridge, which is designed to minimize white dust.
