Expert Rating:


Breathe easier and maintain a healthy indoor environment with our Air-O-Swiss 7147 Ultrasonic humidifier. This powerful humidifier allows you to choose between a comfortable warm or cool micro-fine mist for relieving dry skin, sinus headaches, asthma and cold symptoms. An Intelligent Temperature Compensation (ITC) technology keeps your mind at ease by monitoring the temperature and automatically adjusting the humidity output when air conditions change. A Hydro Stick provides fresh humidification performance while a replaceable demineralization cartridge prevents lime scale and mineral residues. And that's not all! Other specially designed features include easy-to-operate soft-touch digital controls, a built-in hygrostat, programmable timers, empty and cleaning indicators, ultra-quiet operation and low energy consumption. Covers up to 650 square feet and comes with a 3 year warranty.


  • Room coverage: 650 sq. ft.
  • Optional cool or warm mist for optimal comfort
  • Provides a quick and powerful output of the mist into the air
  • Intelligent Temperature Compensation (ITC) - monitors the temperature and automatically adjusts the output when conditions change
  • Has a built-in hygrostat for controlled humidification. Thus if the air is too dry, the humidifier will automatically switch on. As soon as the desired humidity level is reached, it will switch off
  • Hydro Stick provides constant freshness in humidifier
  • Demineralization cartridge to prevent lime scales and mineral residues
  • Ultra-quiet operation

  • Adjustable timer: 1 to 8 hours and continuous use
  • Digital soft-touch controls and display
  • Dual Mist output direction control: outlet can be positioned in any direction
  • Cleaning indicator: comes on automatically every 2 weeks, depending on the level of use (recommended cleaning time)
  • Transparent water tank: clearly indicates water level. There is also an empty indicator alert on the display
  • Long, durable and sturdy lifetime thanks to industrial strength titanium membrane surface
  • Made in Korea


Cleaning: The recommended cleaning intervals depend on the air and water quality, as well as operating times. Every two weeks the water tank and base should be cleaned and rinsed with water only. Only use the brush that is included to clean the membrane once a week. Change the water in the tank at least once a week if water is standing for more than a week.

Replacements: The Hydro Stick is an advanced water maintenance system that ensures your humidifier's functionality while providing fresh humidification performance. It needs to be exchanged a year after it has first been used. The demineralization cartridge has to be replaced every 2-3 months. If the water is very hard, it may be necessary to replace the cartridge earlier. White dust around the device is a sure sign that the cartridge needs replacing.

Product Usage

Please note: In order to maximize the performance it is recommended the unit be placed at least 2 feet off the floor to allow the mist the opportunity to evaporate before hitting the floor and to eliminate the carpeting or wood floor surrounding it from becoming damp.

The following situations could contribute to excessive white dust so are recommended to be avoided:

  • Using water that has been treated by a water softening system could result in an increased incidence of white dust due to the excess sodium in the softened water. Therefore, it is recommended to use water that bypasses the system, bottled, or distilled water.
  • Use of this product with a negative ionizer air purifier or air cleaner with an optional post ionizing function could contribute to an increased collection of dust on surfaces. If this occurs try operating this product without the negative ionizer air purifier or with the optional ionizing function on the air cleaner off.
