What is an Ultrasonic Humidifier?
Ultrasonic humidifiers rely on a metal plate that makes sound vibrations at an ultrasonic frequency, unlike Evaporative humidifiers that utilize fans to evaporate the water inside and expel the water vapor into the air. Such vibrations, moreover, are responsible for producing very fine water mist in which the humidifier diffuses to add moisture into the air.
Generally, ultrasonic humidifiers operate a lot quieter than evaporative humidifiers. It is because of the ultrasonic frequency of the sound waves that are inaudible to humans. Therefore, you can soothe yourself with a good and sound sleep while benefiting from the moisture the humidifier expels. Without any filters to replace and heat to use, they require minimal cleaning and electricity.
