Distilled water is recommended for ultrasonic humidifiers because it does not contain minerals that can build up in the unit and cause problems.

If you’re considering an ultrasonic humidifier for your home, you may be wondering if you need to use distilled water. The answer is yes! Ultrasonic humidifiers work by using high frequency vibrations to create a fine mist that’s released into the air.
