Some knowledge of Air purifier

　　The negative ion generator in the negative ion air purifier uses the way of high-voltage terminal discharge to emit a large number of electrons into the air. Only a few of these electrons hit the oxygen molecules, which will convert oxygen into negative oxygen ions and ozone, and then the negative ions will be released from the air purifier. Intermediate discharge can eliminate static electricity when encountering objects including human body. Therefore, most anion air purifiers on the market are difficult to produce anion equivalent to nature. On the contrary, they will release a lot of static electricity and ozone harmful to human body. This is a problem of technical limitations.

　　Advantages of anion air purifier

　　1. Improve air quality: negative ions can improve indoor air quality, making people feel like in fresh air after rain. Many seaside or lakes have many negative ions, and there are also many negative ions in rural areas, so why is the air in rural areas and seaside particularly good.

　　2. Improve sleep: running anion air purifier at night can promote body metabolism and improve sleep quality.

　　3. Biological effect: negative ions are called air vitamins. Negative ions can promote the synthesis and storage of vitamins in the human body, strengthen and activate the physiological activities of the human body.
