• Question: What Is The White Dust On My Humidifier?

  Answer:

  High mineral content in your water, also known as hard water, may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. The higher the mineral content (hardness) of your water, the greater the potential that an Ultrasonic humidifier may produce white dust. White dust is not a result of a defect or flaw in the humidifier. It is a result of the amount of mineral suspended in the water you are using.

  To minimize the amount of white dust, use a mixture of distilled water with tap water in your tank
