This humidifier sends a mist of cold water (no risk of burns to young children) for humidifying the room to a healthier and less dry air. The document is useful even if the product is very intuitive. Fill the tap water tray (upside down), it is placed on the base and pressing ON / OFF. The camera detects the humidity of the room. Then you set the desired level of humidity. Be allowed to operate either adjusting the timer. All that from 5 buttons under the LED display so friendly. The water passes through a microporous filter which provides a healthier vaporization. There are three steam power levels if it is more or less in a hurry! One can also direct the steam jet with its adjustable nozzle 360. The bin is a large autonomy to take a full night (15h). The unit is very quiet, only the blue light can be bothersome at night in a room. The off night mode only the LED display. I turn it on a few hours before going to bed. I am the recommendations for cleaning and I think use demineralised water afterward and add a few drops of essential oils to scent and promote sleep! I am delighted with this very useful and product design, and recommend it to people sensitive to air too dry our homes. A gentle breeze in summer or healthy humidification in winter when the heating is on. Congratulations!
