Buying an air purifier can't just look at the gimmick, the priority is the purification effect

　　Affected by the haze weather, sales of air purifiers continue to be hot. However, many consumers are very blind when choosing an air purifier and do not know how to choose an air purifier at all. It can be said that the consumption of air purifiers is still in the groping stage, and some manufacturers have taken advantage of the lack of consumer awareness and created various publicity stunts to mislead consumers, causing consumers to not know how to start when purchasing products. .

　　Director Song Guangsheng of the National Indoor Environment and Environmental Protection Product Quality Supervision and Inspection Center told reporters that purifiers have been developed for decades and generally have three major functions of removing PM2.5, chemical pollutants, and sterilization. The problem is that the problems of major companies exaggerating the concept of publicity and hype are very obvious, such as failing to achieve the efficiency of the publicity label, or having the function of removing formaldehyde out of nothing.

　　According to the person in charge of the air purifier marketing department, consumers buying air purifiers are nothing more than the three goals mentioned by Director Song: one is to remove PM2.5 particulate pollutants, including dust, second-hand smoke, pollen, etc.; It is sterilization (killing harmful microorganisms, including bacteria, viruses, molds, etc.); the third is chemical pollutants, including formaldehyde, benzene, xylene, TVOC, etc.

　　The person in charge reminded consumers that before the introduction of the new national standard, when consumers buy air purifiers, they only need to check the purification effects of the above three aspects of the air purifier according to actual needs. The most reliable basis for judging the purification effect is the test report issued by an authoritative testing organization in China. Tips to read the test report:

　　First, it depends on the testing organization. There are currently several authoritative testing organizations in China, mainly in Beijing, Guangzhou and other places; the second is the testing conditions, such as the testing time, initial concentration, and the size of the testing chamber. The detection time should not exceed 6 hours, the shorter the time, the higher the gold content of the detection data. This is because according to the household appliance usage habits of Chinese households, there are fewer devices that are turned on 24 hours a day. Generally, they are turned on after returning home from get off work or in the office, and turned off before leaving home after work or returning home from get off work. Therefore, those long-term, such as 24-hour test data are basically of no reference value; third, it depends on the test report of the model to be purchased, because according to Director Song, there are indeed some manufacturers in the market that borrow from certification, testing or government authorities. The certification is used for publicity, replacing the testing data of all products with the testing data of one product, or making several indicators at the same time. The good indicators are used, but the ones that are not closed are concealed. Therefore, when consumers plan to buy a certain model of purifier, they must read the test report of that model.

　　In addition, air purifier manufacturers also specially remind consumers: air purifier noise, energy consumption, whether it will cause secondary pollution, filter replacement cost, the service life of the whole machine, etc., are also required at the time of purchase. Factors to consider. But the core indicator of priority is the purification effect of the air purifier.
