　　With the improvement of living standards, more and more people are beginning to realize the importance of air quality to the living environment. How to enjoy the fresh air at home? Many families choose to buy air purifiers. However, in the face of various air purifiers on the market, how should we choose? What should be paid attention to when using an air purifier?

　　"Chengdu Evening News" reminds consumers that they should pay attention to the following points when purchasing air purifiers:

　　First of all, to clarify the purpose of use, you should buy a purifier that has a purification effect on PM2.5.

　　Second, according to national standards, a truly effective air purifier must achieve the "three highs and one low" energy efficiency index.

　　High clean air volume: The clean air volume (CADR) is an indicator of the purification effect of the purifier. The larger the CADR value, the stronger the purification capacity of the purifier and the better the purification effect;

　　High cumulative purification capacity: the higher the cumulative purification capacity (CCM) value, the more pollutants are purified, and the longer the filter life is;

　　High energy efficiency value: the higher the energy efficiency level, the more power saving;

　　Low noise level: The working noise of the instrument is generally lower than 50 decibels, which is relatively quiet. You can observe the prototype for intuitive experience when purchasing.

　　In addition, other factors must be considered when purchasing. According to China.com.cn, the air pollution sources of newly decorated rooms are mainly formaldehyde, benzene, TVOC, etc. It is advisable to purchase products with a large amount of clean air and high purification energy efficiency. If there are patients and children at home, the air purifier's ability to remove microorganisms should also be considered when choosing a purifier, that is, the higher the sterilization rate, the better.

　　Buying a suitable air purifier does not mean getting it all done once and for all. How to use and protect the air purifier is also very important. In this regard, the "Beijing Youth Daily" put forward the following suggestions:

　　1. The most important thing is to replace the filter. If consumers cannot replace the filter in time during use, it will not only have no purification effect, but may become a source of secondary pollution.

　　2. Long-term use of air purifiers will reduce the concentration of carbon dioxide, so in non-severe haze weather, opening windows for ventilation is still necessary.
