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 - four 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 Cell is an advanced water maintenance system that ensures your humidifier's functionality while providing fresh humidification performance. It needs to be replaced every 1 - 2 months depending on water quality. 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 Boneco 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.
