In response to the product quality of air purifiers, the China Consumers Association scrutinizes the issues that have been more intensely reflected by consumers: First, many companies are complex and some companies are short-lived, and there has been “purification of consumables such as screens after purchasing productsâ€. "Orphans"; Second, the product comes on stream, false publicity, consumers buy such products as tasteless; Third, after-sales service lags behind, consumers buy purifier products are not after-sales service, and some even become a secondary source of pollution .
Lu Jianguo, deputy chief engineer of the China Household Electrical Appliances Research Institute, said that China's home appliance products rarely have 3C certification, and air purifiers also do not have 3C certification standards. With the promulgation and implementation of the new national standard for air purifiers, the phenomena of cohabitation in the industry have been alleviated to a certain degree, and the falsification of the product index has been improved to some extent.
How do consumers buy purifier products? China Consumers Association recommends that when selecting air purifier products, consumers should purchase products that implement the new national standard, and select products that clearly indicate CADR (clean air output ratio), CCM (purifier cumulative purification amount), high energy efficiency, and low noise. Attention should be paid to the recognition of the business promotion of formaldehyde removal efficiency, medical grade, antibacterial, sterilization, etc. Merchants should issue inspection reports of third-party professional organizations; choosing air purifier products is not as expensive as possible, the higher the label value, the better. According to actual needs, such as the application of the area and purification needs to choose. Many nominal helium air purifier products do not necessarily have the function of removing formaldehyde. In order to remove formaldehyde and other pollution caused by decoration, it is recommended that consumers select the formaldehyde removal air purifier product with the highest possible CCM value.

"China's air purifier market has annual sales of 5 million units, an annual growth rate of 20% to 30%, of which 30% of the products are unqualified." Liu Qing, deputy secretary-general of China Consumers Association in the Chinese consumer on the 14th The “Conference on Indoor Air Purifier Consumer Education†organized by the association stated that the quality of air purifier products is uneven and product promotion is multifarious, which has made it more difficult for consumers to choose.
