Why did foreign air purifiers go down the altar?

　　According to the current development of the international market, many consumers prefer foreign and imported products, and believe that the quality of foreign products is greater than that of domestic ones. However, in terms of air purifiers, things backfired. In 2016, a total of 6,907 batches of import and export commodities were randomly checked across the country, and 1,906 batches of unqualified products were detected, and the unqualified detection rate was 27.6%. Among them, the unqualified detection rate of imported goods was 28.4%, and the unqualified rate of air purifiers, which attracted much attention, was as high as 23.2%.

　　The quality problems of unqualified performance indicators mainly include four aspects: noise, clean air volume, purification energy efficiency, and standby power. From these, it can be seen that there is dereliction of duty in the early quality control of foreign-funded industries. This leads to frequent product quality problems.

　　1. Environmental factors have become a means of rapid publicity for foreign air purifiers.

　　Air purifiers are currently a popular household appliance industry. The reason for its popularity is also to clean the air and clean the home. The air pollution problem at home and abroad is getting worse day by day. It has also become a natural publicity tool for air purifiers. There are many air purifiers on the market that remove PM2.5, formaldehyde, and indoor pollution. Exaggerations abound. And consumers have also given a lot of trust to foreign-funded industries. As a result, prices do not compare after purchase.

　　Industry experts generally believe that foreign brands frequently expose quality problems, partly because foreign brands directly move products from other markets to China, and the localized innovation and improvement for the Chinese market is insufficient. A previous comparative test conducted by Qiu Zhaoyun, the main drafter of the national standard for air purifiers, also showed that the four domestic brands are better than the four European and American products in terms of purifying smog and formaldehyde. The technical staff pointed out that the reason why Chinese brand products have high purification efficiency lies in the air volume. Chinese manufacturers often design the diameter of the turbine between the air inlet and the wind wheel to be relatively large, and the air outlet is also designed to be relatively smooth. The outlet area of foreign products is usually not as large as that of Chinese products.

　　2. The natural selection factor of consumers.

　　in current consumer perceptions. Foreign-invested industries are better than domestic industries. Of course, to tell the truth, there are many foreign-funded industries that have done well and are very popular among consumers. This also created the brand effect. I feel that the brand has been deeply ingrained in everyone's mind. However, this air purifier spot check has completely reversed everyone's consumption concept.

　　Through measurement, experts pointed out that domestic brands are worse than foreign brands in terms of popularity, but according to the test, the purification ability of domestic brands is not worse than that of foreign brands, or even better than them.
