Removable Tank and Demineralization Cartridge

Hydro Stick Placement


About Ultrasonic Technology: uses high-frequency vibration to generate a micro-fine mist. A fan blows the mist into the room where it immediately evaporates. Ultrasonic humidifiers consume very little power, are virtually silent and produce a fog-like mist.

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.

See all Air-O-Swiss replacement filters and accessories.

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.

Air-O-Swiss has done it again with the addition of this model to their line-up. We like the simplicity and the modern stylish look and that it can humidify a large area up to 650 square feet.

Pluses:

  • The AOS U600 packs a powerful punch and will quickly and sufficiently humidify a room up to 650 square feet if the conditions are right (such as having the door closed). Due the amount of mist it can disperse we always recommend placing the humidifier on a nightstand or stool at least 2 feet high to prevent the floor from getting soaked.
  • Our Air-O-Swiss ultrasonic humidifiers are virtually silent and make an excellent choice for a bedroom. No loud fan noise or constant dripping of water is heard with the AOS U600.
  • Its Hydro Stick and demineralization cartridge ensures only safe, hygienic mist is being dispersed. Plus, such protection will keep the tank and components in tip-top shape and prolong the life of the unit.
  • Want a humidifier that will keep constant comfort without much effort on your part? The AOS U600 features a manual humidistat that allows you to choose a desired humidity range and then will automatically adjust the humidity output when conditions change in the room.
  • The compact size and shape of the tank made it one of the easiest of humidifiers to fill and carry. It can be filled in most kitchen sinks and some deeper bathroom sinks (the tank is 9' high).
  • Has the option of warm or cool mist (both options humidify effectively). The warm mist can feel more comforting in colder climates or in a child's bedroom.
  • Features easy-to-use manual controls which makes it a good choice for those who want simple, no-frills operation.
  • This is a humidifier that was carefully designed with durability and reliability in mind and will go above and beyond with humidification performance compared to lower-end models. The AOS U600 and its digital U650 model are the only Air-O-Swiss humidifiers that come with a stainless steel heat sink instead of plastic surrounding the titanium transducer.
  • The AOS U600 has a sleek, modern design that fits well into almost any room décor without being too much of an eyesore.

Minuses:

  • Does not display the actual humidity in the room.
  • Manual adjustable humidistat does not allow you to set a specific humidity goal level.
  • Cost of the humidifier and replacement cartridge and Hydro Stick is a bit more than the average humidifier but well worth the money.
  • If you are humidifying one room, you will need to fill this humidifier up once per day, but if humidifying larger spaces fill-ups will be more frequent.


Summary:

The Air-O-Swiss U600 is perfect for someone who is looking for an effective humidification appliance with a modern look but not all the bells and whistles to complicate its operation. We really liked the variable mist control that allows the end user to fine tune how much mist to add to the air. Plus it still gives you the option of warm or cool mist operation. Air-O-Swiss, a highly respected brand when it comes to humidification, has once again designed an efficient, powerful and user-friendly humidifier that will allow you to enjoy clean, healthy air during those drier periods.
