The dust consists of the minerals that are found in your water supply.
If you live in a hard water area, the humidifier will leave a
noticeable layer of dust on objects in the room.

One humidifier manufacturer suggests in the owners manual, "If this
humidifier will be operated in a room containing electronic equipment,
USE DISTILLED WATER ONLY".
