This thing is so quiet!, November 18, 2009

This humidifier works extremely well. More than anything I wanted a quiet humidifier, and wow is it ever. It is easily worth the money for how silent it is. In order to hear it run, I would have to be standing right beside it, and even then it is very quiet. Our home is very open, so we did not want a loud machine as it would affect our dining room, kitchen, and living room. We are using it for an area of about 500 square feet and it handles this are well. I should note that we haven't yet reached our coldest months where the house would usually be much more dry, but this machine seems very capable.

happy but a little unhappy, November 13, 2009

I really, really like the Air-O-Swiss humidifier. It has solved some of the problems that we were having with dry air. We only run it at night when we are sleeping and it seems to do an excelent job and it is also very, very quiet which was a big priority for husband. I must also say that the company that we delt with for the purcase was not a good experience and I hope that I never have to deal with them again. I think that maybe the unit was originally sent out to another customer and they did not return all of the parts that were suppose to be included with the shipment from the manufacturer in Switzerland. We never did get an instruction booklet on how to properly care for the machine and I had to download a copy off of the internet. So, the machine does all of the things that it is suppose to do and we are very happy with it, but the customer service leaves a lot to be desired.......

Very inconvientent and worthless, November 5, 2009

What is not said here on Amazon.com is that this must be put on a 3 feet stand, and then the nozzel must not be interferred with, unlike my others that can sit on the ground. In the end there is no place in our home that we can set it up, so for us it is absolutely worthless. Before buying make sure that you have an unimpeded place of 3 feet hight that you can set it on, that is not in the middle of your room, unless you want the staring piece of your room to the this humidifier. The enginerring on it, is not good.

Very disappointing - what a waste of money, November 4, 2009

I researched this humidifier extensively and it seemed to be one of the very best, many positive consumer ratings on numerous websites. I loved that it went to so much effort to achieve especially clean water output. And there were so many digital options that seemed great to have as well. But what good is any of that when it only worked well for a single year. I was a very diligent humidifier user too - cleaning it properly according to the manual, making sure to replace the things that need replacing. It was annoying to continuously have to take care of the machine, cleaning the inside compartment the best I could, and dishing out all the money for the expensive replacement parts that it needed for its normal 2-3 month maintenance issues. But I kept thinking at least its worthwhile - it works so well...Not for long! The second year the mist output was next to nothing, the dirty water sign was always flashing so I had to clean it every other day, and worst of all the circular "membrane" was so delicate that I accidentally damaged it in a routine cleaning - and as far as I know its not replaceable. (Although even if it was replaceable I refuse to spend one more penny on this money pit of a machine) I wish I had chosen a different brand altogether. Its very irritating that Air-O-Swiss passes themselves off as such high quality when their machines are just bound to break because they are so delicate and hard to clean effectively. If you want to waste a lot of money and time on a product that will only last a very short time this is the product for you.

Excellent humidifier!, October 23, 2009
I have had this humidifier (Air-O-Swiss Ultrasonic 7135) for about a year now. I used it all winter long because it gets very cold here and the air is very dry. I use distilled water in it. It worked very well! I am extremely pleased with this product.
