To propel water into the surrounding air, impeller humidifiers use an elevated disc with holes that rotate at peak speed. They are inefficient and noisy, but they are affordable.  

Ultrasonic humidifiers produce water droplets by ultrasonic vibrations, which can be seen as a cool mist or are completely invisible.  

Evaporative humidifiers circulate air through a diffuser and absorb moisture as it passes over all the corners of the room area.
