Rated 4 out of 5Â by chicagoboy Very happy with the product
I've had this for about two months now and run it constantly. I'm very pleased with the performance. I'm using Reverse Osmosis water so I don't get any white dust even without using the built-in filter. The user manual said that with RO water the filter isn't necessary so I left it out. The humidistat works well but has a minimum setting of about 40% RH; that seems fine for me and I have it set a little bit up from minimum.
One disappointment, for me at least, is that the low-water indicator is a two-color (red/green) LED that shows green for power on (this wasn't mentioned in the manual) and red for low water. Since I have a color-perception deficiency I can't tell that it has changed to red unless I'm actually looking at it when it changes.
Note that the directions say to put the unit on a chest or table about 3 feet off the floor, but then say that if the mist contacts a surface then the surface can be damaged. Be careful if you're placing it on wood furniture.

This humidifier has been great. I have been using it steadily since I purchased it. It is quiet and the cool mist cools down my room so it is not as hot. I have allergies and usually cough at night . This product has helped stopped my coughing so I get a better night's rest. I highly recommend it!

The Air-O-Swiss is whisper quiet and dispenses more moisture than any other humidifier I've ever owned. It has a nice contemporary design and the best part is that you can't hear it. It has an indicator light to let you know it's running and another to let you know when it runs dry. Love it!
