  • Steam sterility, does not depend on the purity and quality of water;
  • It is used in medicine as a device for inhalation;
  • Safety. When the lid is not closed tightly, the device will not work, and when all the water in the tank evaporates, the device will turn off;
  • Filters and cartridges are not used, so you do not have to constantly replace them;
  • The presence of an indicator that shows how much water is left;
  • Availability. The prices for steam appliances are much less than for other types.


  • Consumption of a large amount of electricity;
  • The boiling liquid in the device makes a characteristic noise, which can contribute to restless sleep when working at night;
  • Hot steam increases the temperature in the room;
  • This type of humidifier is unacceptable to put in free access to children, you can get burned by hot steam.

Ultrasonic Humidifier

This device works on the basis of a complex process (Fig. 1). A special membrane makes vibrations at high frequencies, due to which the water begins to vibrate and breaks into small dust particles. With the help of a fan, these particles are carried out, in this way the humidity in the room increases.

There is an opinion that ultrasound negatively affects humans and animals, but these data are unfounded. According to numerous studies and facts, it has been proven that modern devices are safe and do not affect the body in any way.

  • The presence of a rotating steam atomizer, thanks to which you can choose the direction of the jet;
  • The energy consumption of such a device is very small, but this does not prevent it from being the most effective device for humidifying the air;
  • Thanks to the built-in hydrostat, the device automatically turns off when the desired moisture level is reached;
  • Also, the automation turns off the device at the end of the presence of water in the tank.

The opinion of Dr. Komarovsky

Komarovsky Evgeny Olegovich draws attention to several factors influencing the choice and determination of which air humidifier is better:

  • Safety;
  • The frequency of its use;
  • What water will be poured into it;
  • The need for additional features.

If the device will be in the nursery, you should pay attention to safety. A steam humidifier differs from an ultrasonic one in the presence of hot steam, so either it must be placed out of the reach of children or opt for an ultrasonic device.

When dry air prevails in the room all the time, especially in winter, it should be noted that the device will work almost around the clock. It is known that steam-type appliances consume a lot of energy, and in this case their use is not rational.

The difference between an ultrasonic humidifier and a steam humidifier is manifested in the sterility of the outgoing steam. A device with ultrasonic humidification, in this regard, leaves a residue on the surfaces. What can not be said about the steam device. Therefore, when determining which air humidifier is better, it should be taken into account that for ultrasonic it is necessary to additionally choose water, and steam kills all microbes and does not remove substances in the water, regardless of its origin.

Many devices for increasing the humidity of the air have many additional functions. Useless, according to Dr. Komarovsky, is the presence of sensors for determining temperature and humidity. These sensors show data that is measurable at the source of moisture, and not near the crib, so they will be unreliable.

The possibility of using a steam device for the purpose of inhalation is also an unnecessary thing. In the presence of a humidifier, the need for inhalations disappears, therefore the importance of this function is denied by Evgeny Olegovich.

When determining which humidifier is best, there are many factors to consider that have an impact on the individual selection process. It is impossible to give a fundamental advantage to one of these devices, since these two types satisfy different needs and have differences in functionality.

It can be concluded that an ultrasonic humidifier differs from a steam humidifier in greater safety, as well as economy and low noise levels. However, the steam device has the advantage of steam sterility, additional functions of inhalation and aromatherapy, as well as a lower price category.
