This Digital Warm & Cool Mist Ultrasonic humidifier uses high-frequency vibrations to turn the water into a micro-fine mist that creates a comfortable environment in any room. Choose the pre-heating function and mist exits the appliance at a pleasant 104°F. A replaceable demineralization cartridge ensures water mist without lime scale or mineral residues. The included Hydro Cell uses activated carbon technology to help reduce heavy metals, impurities, odor causing chemicals and pesticides from your household tap water.

Comments about Air-O-Swiss Digital Warm & Cool Mist Ultrasonic Humidifier, 1 Each:
First of all, let me say I love this unit. It seems to be manufactured to high standards and feels and looks of high quality. The unit's operation is seamless and very customizable and the air quality produced is outstanding.
However, the product summary on Drugstore.com only mentions maintenance as regular cleanings and an annual change to the Hydro-Stick. I bought this product because of this.
The problem, is that the unit requires weekly or bi-weekly cleanings and a changed demineralization cartridge (or contents of cartridge) every 2-3 months. I have hard water (in KS) and was under the impression that the primary maintenance to the unit would be once per year.
Now I will have to stock up on expensive accessories that I didn't plan on needing or spending money on.
Great unit, but more revealing/detailed info sure would have helped. Also it's hard to fill because there is no handle to hold it buy on the side you are filling it at.
Bottom Line Yes, I would recommend this to a friend
