Negative ion air purifier: an environment-optimizing electrical appliance that uses negative ions generated by itself to purify, remove dust, deodorize and sterilize air. It is different from the traditional air purifier in that negative ions are used as the action factor to actively capture harmful substances in the air, while the traditional air purifier uses a fan to exhaust air and a filter screen to filter dust to purify the air. This is called the purification principle of passive adsorption filtration, and the filter screen needs to be replaced regularly, while the negative ion air purifier does not need consumables.
However, negative ions with smaller particle size have good biological activity and easily enter the human body through the blood-brain barrier to exert their biological effects.
The harm of negative ion air purifier is that when negative ions are generated, ozone will be generated as a derivative, and when the ozone concentration exceeds the standard, it will cause harm to human body.
The negative ion health care machine is a kind of negative ion health care equipment for treating and preventing diseases by generating negative air ions, which is an essential external physical factor 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. Artificial negative ion generation technology has reached the ecological level. It is a negative oxygen ion generator using negative ion converter and nano fullerene negative ion releaser technology, which can generate ecological negative ions equivalent to nature, that is, small particle size negative ions.
