Types of humidifiers
According to the principle on which they operate, humidifiers are divided to steam humidifiers, ultrasonic humidifiers and cold humidifiers. Steam humidifier brings water to a boil, it is subsequently cooled and discharged into the space. This destroys any bacteria, but the disadvantage of this humidifier is a higher energy consumption. Ultrasonic humidifier operates on the principle of formation of microdroplets using the high-frequency ultrasonic oscillator.
Ultrasonic and cold humidifiers
Ultrasonic humidifiers produce visible fine steam and are popular for their low power consumption and quiet operation. Cold humidifiers use the simple principle of natural evaporation of air, which we know from nature. The filter captures water droplets, which are sent into the air by the fan. The companies specializing in the development of humidifiers include Bionaire , Sencor or Medisana .
