Ultrasonic humidifiers use high-frequency vibrations to generate a micro-fine mist which is output into your room for increased humidity. Ultrasonic cool mist humidifiers are best used to combat allergies and seasonal flu symptoms. If your house has excessively hard water, it will use a water softener to counteract the high mineral content. Unfortunately, a water softening system uses calcium, magnesium, and sodium, and those high sodium levels will create white dust when used in a cool mist humidifier.
Our cool mist models are our top choice for your bedroom humidifier since they operate almost silently.
