How is an ultrasonic humidifier different than a “regular” humidifier?

An ultrasonic humidifier works similarly to a stereo speaker while staying whisper quiet. A nebuliser vibrates at an ultrasonic frequency to create a mist that easily dissipates into the air rather than droplets that fall to the ground. Ultrasonic humidifiers are highly effective, but because of the vibrations, you may notice a fine white dust collecting from the high-mineral water. If so, try a Crane Demineralization Filter.
