Ultrasonic humidifiers

Ultrasonic

— with this method of humidification, the role of the evaporator is played by a plate vibrating at an ultrasonic frequency — due to this, the water that falls on it is sprayed into a fine mist. It is the most popular principle of operation, it is also considered the most suitable for home (domestic) humidifiers. The reason for this is several advantages. Firstly, the water cloud has a room temperature and the risk of getting burned by steam is zero, which is especially important if there are small children in the house; however, in some models, it may be possible to heat the steam (see "warm steam"). Secondly, ultrasonic models have good efficiency and performance with low power consumption. Thirdly, it is not audible to a person, and the main noise is created by the fan — and the level of this noise is low. Fourthly, devices of this type can be made light, compact and travel-friendly. The disadvantages of ultrasound include the fact that it "evaporates" not only water but also salts dissolved in it. In fact, this means that well-purified water must be used for work — otherwise, a hard-to-remove white plaque may appear on objects in the room.
