What are the water quality requirements for a fog free humidifier?

　　The requirements for water quality in fog free humidifiers are relatively low, as follows:

　　Tap water is available: Mistless humidifiers can usually use tap water because their working principle is to slowly evaporate moisture into the air through cold evaporation technology, rather than directly atomizing water like foggy humidifiers. In this way, impurities in the water will not be carried into the air, so tap water will not cause air pollution when used.

　　Small impact on water quality: Compared with foggy humidifiers, non foggy humidifiers have lower requirements for water quality. Even chlorine and other substances in tap water can inhibit bacteria to a certain extent. Compared with purified water, tap water even has advantages in certain aspects.

　　Regular cleaning: Although fog free humidifiers do not require high water quality, it is still necessary to regularly clean the equipment to avoid bacterial growth and maintain the humidification effect

　　Overall, fog free humidifiers, due to their design and working principle, can effectively use tap water, reducing strict requirements for water quality and making them more convenient and economical for household use.
