What is cool mist humidifier?

Coolmist units are designed to provide only cool moisture into the air. The mist released is not too cold but usually at room temperature. However, there are two kinds of cool mist humidifiers such as the evaporative and ultrasonic ones. The two types create cool mist but work differently.

The evaporative models have fans and wick filters. The unit uses fan to blow water over the wick thereby converting into cool mist. On the other hand, ultrasonic ones works by vibration technology breaking down water molecules into tiny droplets of water resulting into cool mist.
