Negative Ion Release: Crystal salt humidifiers typically release negative ions, which can help purify indoor air. They adsorb and neutralize some pollutants in the air, such as dust, bacteria, and other particles, thereby improving air quality.

Aesthetic Value: Crystal salt humidifiers typically have a beautiful appearance because they use natural salt crystal blocks, which come in various colors and textures. They are often used as decorative items to enhance the harmonious atmosphere indoors.

Adjustable Humidity: Some crystal salt humidifiers come with adjustable humidity controls, allowing you to customize indoor humidity levels according to your needs.

Skin Care Benefits: The negative ions and evaporated water vapor from crystal salt humidifiers may also have some skin care benefits, helping to keep the skin moisturized.
