Ultrasonic, Filter Free Cool Mist Humidifiers FAQs
Question: Why is there white dust?
Answer: With ultrasonic humidifiers the mist put out by the unit is a visible mist. These types of humidifiers turn the water into a mist and release it out into the air. The minerals that are in the water are also in the mist being put out by the machine. As the moisture evaporates into the air, the minerals are left behind and will settle around the room as dust, and in most cases it is white. It is not harmful in any way; it is just the contents of your water. The amount of white dust you see is directly related to the hardness of your water. To reduce the amount of dust, distilled or purified water can be used in your machine
Question: Why is there condensation on my walls, ceiling, windows, etc?
Answer: If there's condensation, then the humidity level in the room or the house is too high, and the air is becoming saturated with water. We recommend waiting to use the unit until the moisture level drops or using the unit on a low setting. A hygrometer can be helpful in determining the actual room humidity.
Question: Why is there no mist or steam coming from my unit?
Answer: The nebulizer, or white circle, that you see in the bottom of the base vibrates at ultrasonic speeds to create the mist that this unit gives off. Minerals from your water will collect on the nebulizer and once they harden, the nebulizer slows to a pace that is too slow to create mist. Clean the nebulizer every week to ensure proper functionality.
