What are the uses of negative ion air purifiers? What is the principle?

　　Negative ion air purifier refers to the use of negative ions as the main element of air purification in the air purifier, and most of the negative ions are generated by the negative ion generator. Negative ion generator is a device that generates negative ions in the air. After special treatment of the direct current or alternating current, the negative ion generator can easily combine with the oxygen (O2) in the air to form negative ions in the air, which is a healthy life. A substance that is lacking, when the content of negative ions in the air exceeds a certain value, it not only has the effect of sterilizing and purifying the air, but also can turn oxygen molecules into oxygen-carrying negative ions.

　　Of course, the application of negative ions to air purifiers is mainly based on the fact that charged gas ions are easy to charge particles (losing or gaining electrons). The impact of ultraviolet radiation, waterfalls, fountains or ocean waves may all produce air ions. Most of the free electrons generated by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. Therefore, air negative ions are often collectively referred to as " Negative oxygen ions". In cities, because there are more pollutants in the air, the larger particles of pollutants are easy to absorb the "ions" in the air. Without the use of equipment, it is more obvious to feel negative ions in the forest, especially when we are walking in the forest in the early morning or evening, our tired body is always relaxed. It is not only that we temporarily forget the busy daily life. Life, and at the same time, under the action of negative ions, promote the body's metabolic activities, so that the body can obtain sufficient energy. Therefore, many people prefer to go to forest parks and other places when there are more negative oxygen ions.

　　In addition, when the ions combine with the particles in the air to form a charged particle cluster, its weight will also increase. When the mass reaches a certain level, the particle cluster will fall to the ground, which is to some extent the particles in the air. Reduce, realize the function of dust reduction and dust removal. While purifying the air, the negative ion air purifier can also enhance the freshness of the air.
