Air is composed of innumerable molecules and atoms. When the air molecules or atoms lose or obtain electrons, they form charged particles, known as ions; with positive charge called positive ions, negative charge called negative ions. Negative ions in the air is a negatively charged gas ions, negative ions can not only contribute to the synthesis and storage of vitamins, strengthen and activate the physiological activities of the human body and other biological life activities have a very important impact, it is also known As "air vitamins". And that it is like food vitamins, like the human body and other biological life activities have a very important impact, and some even think that air anion and longevity, called "longevity factor." For each positive and negative ions, its life is short, usually only a few tens of minutes. After the thunderstorm the air is good, this is the feeling we have experienced, it is because, when the thunderstorms after the gas molecules in the air under the action of lightning, ionized negative ions.
In general, people need about 13 billion a day anion, and our bedroom, office, entertainment and other environments, can only provide about 1-2 billion. This huge contrast between supply and demand, often easily lead to pneumonia, bronchitis, respiratory disease. Centralized heating and air-conditioning equipment, air conditioning systems, negative ions are often driven away. Synthetic fiber, carpet with positive charge easily absorb negative ions. Steel, fibreboard absorb negative ions.
