Ultrasonic humidifiers

Humidifiers can be mainly divided into ultrasonic, evaporative, and electric heating, of which ultrasonic is the most common.

Evaporative humidifier

The Evaporative humidifier accelerates the air through the humidified evaporating core through the fan to achieve the family effect. The core component evaporates the core, which is mostly cylindrical and has strong water absorption. In addition, the evaporation core has a certain ability to purify/soften the water quality, so the water quality requirements are not ultrasonically high.

Evaporation requires a large amount of air, and the noise is relatively high. Due to the built-in evaporation core, the volume is relatively large. And the price is generally higher.

Electrothermal humidifier

Electrothermal humidifier, also known as steam. The principle is very simple, that is, the water is boiled to boiling, and the water vapor is poured out to achieve the purpose of humidification. Well, the electric kettle can be regarded as an electric humidifier without lifting the bar.

The water mist generated by the electrothermal humidifier is a Warm Mist. Most of the ultrasonic and evaporative types that are directly discharged without heating are Cool Mist. In addition, there is a humidifier that supports both cold and hot fog modes, most of which are ultrasonic + electric heating, and a few are evaporative + electric heating, which is a compound humidifier that supports electric heating.

Shopping advice:

1, Ultrasonic type is usually cheaper, evaporation type is generally more expensive, and the electric heating price is middle.

2, Ultrasonic and evaporative powers are typically tens of watts, and electrically heated and composite types are typically several hundred watts. Pay attention to the cost of electricity.

3, Ultrasonic humidification has high efficiency and low noise, but it has certain requirements for water quality. If the water quality is hard, it may affect the humidification effect and machine life, and there may be a “white powder” phenomenon. Therefore, it is recommended to use pure water as much as possible and change the water tank in time. water.

4, Evaporation requires a large amount of air, and the noise is relatively high. Due to the built-in evaporation core, the volume is relatively large, and there are an obvious air inlet and outlet. Note that the evaporative type needs to be cleaned regularly to replace the evaporating core.

5, The electrothermal type is relatively rare, the water quality requirements are not high, the humidification ability is strong, but the humidification efficiency is the lowest.

6, Ultrasonic humidifiers meet most home humidification needs. If your local water quality is hard, it is best to use it with pure water or choose a model with a water softener. Evaporative humidifiers are more recommended if the budget is sufficient. If you want a hot fog, choose an electric type or a combination that supports electric heating.
