White dust is not a problem it is from the minerals in the water that form the dust. The humidifier evaporates the water and then the white dust is left in the unit, not sent out into the air. If bothersome, use distilled water or you can purchase one of our Decalcification Filters (FLTDC) to help with the problem.
