In recent years, PM2.5 and haze frequently attack people's lives, which are more willing to change their lives than the passive waiting before. For example, buying air purifiers has become the "standard" of many families. This also contributed to the surge in air purifier sales. According to relevant data sources, in 2014, the retail volume of air purifiers market was 3.6 million, an increase of 50% year-on-year. At the same time, behind the hot market, there are many phenomena such as the brand establishment of various air purifiers on the market, and the uneven quality, which hinders the healthy and orderly development of the industry.

Recently, Shanghai Municipal Bureau of quality supervision and State Administration for Industry and Commerce successively announced and issued relevant contents on "product quality supervision and spot check", "quality and safety risk monitoring results of air purification products" and "special rectification action for air and drinking water purification household appliances". According to the introduction, this special action focuses on the strong problems reflected by consumers: declared that the inspection was conducted by the testing institutions, but not actually tested; The claimed test data is inconsistent with the actual test data; Concealing the test conditions, testing environment and time limit specified in the test standards, but only publicizing the data obtained from the test; Highlighting the publicity of a data and misleading consumers; Without the certification of the testing institution, or without authorization to publicize the certification; Only the partial parts or some part functions of the product, such as filter screen and filter element, are detected, but the commodity has the same function after inspection. This is to protect the interests of consumers and maintain a fair competition market environment.

In addition, in view of the new changes in the development of air purifier industry and consumption demand, the new national standard also includes the market of "purified" air purifier, and the clean air volume (Cadr) is included in the new national standard. The revision of the new national standard, the inclusion of the important index of clean air volume (Cadr) has attracted the attention of the industry. There are two indexes for the effect of air purifier, namely, purification efficiency and clean air quantity. However, the general manufacturer usually only indicates the purification efficiency, but does not indicate the clean air quantity“ In fact, the effective range of air purifier should be considered. The larger the clean air quantity, the greater the effective range of action. " When choosing air purifier products, consumers should pay attention to the Cadr value marked by the manufacturer. The larger the value, the better, which represents the shorter the purification time in the same environment.
