Air ions are indispensable external physical factors for normal physiological activities of human body. Various gas components in the atmosphere do not exist completely in molecular form, and some of them exist in ionic state. Air negative ions, like vitamins in food, have a very important influence on human life activities, so they are also called air vitamins. Because the number of naturally occurring ions in the air is easily influenced by geographical and meteorological factors, it cannot be widely used. Therefore, a variety of artificial air negative ion generation technologies have been developed and made into various types of air ion generators, which are widely used to treat and prevent diseases.
Axelrod air negative ion health instrument applies ecological negative ion generation technology, which can generate ecological negative ions equivalent to nature, that is, small particle size negative ions. Eco-small particles of negative ions have high activity and long natural diffusion distance, and can be released to far places without being blown by a fan, forming a healthy convalescent environment of eco-negative ion bath indoors.
