Ultrasonic humidifier used for water quality has certain requirements, generally divided into two kinds of soft water and hard water, here small make up teach you how to distinguish soft water and hard water:

Method 1 in a clean, dry glass. Drops of amount of water samples in different places respectively. It completely evaporated, the white residue for hard water, vice for soft water. Water hardness, it is to point to the water of calcium, magnesium, iron, aluminum, manganese carbonate and bicarbonate, chloride, sulfate and nitrate all salts, and often contain mercury, cadmium, arsenic, lead, and a small amount of harmful elements. Ultrasonic humidifier with hard water to boil water is easy to make the kettle fouling, waste of fuel by more than a third.

Method 2 respectively with two beakers take amount of water in the ultrasonic humidifier. To the two beakers and add an equal amount of soap and water respectively. Bubble for soft water, less dross. On the other hand, the bubble, scum less for hard water.

Method 3 heating can also use the beaker, leaving more scale is hard water on glass. Because ultrasonic humidifier is hard water contains more soluble calcium, magnesium material water, heat, after these soluble calcium magnesium material into insoluble substance, more precipitation impurities is hard water, impurities, the more the greater the hardness of water.

Ultrasonic humidifier humidification water it is best to use pure water, no clean water containing impurities. Such as tap water, water containing large amounts of calcium and magnesium ions will be deposited on can change disc and humidifier internal water tank wall and over time leads to its load is aggravating, a serious and even produce the problem such as short circuit and burned. In addition, the water contains impurities will deposit on the surface of an object around the humidifier, white powder crystal formation, pollute the environment. So using ultrasonic humidifier humidification must insist to use pure water as the humidifying water.
