Recently, some media reports said that experimental tests revealed that Xiaomi Air Purifier 2 listed on the market in 2015 had a false scavenging capacity in addition to formaldehyde, and that the relevant values such as energy efficiency and noise also deviated from the actual values. Zhimi Technology of Xiaomi's air purifier product series responded to China Netcom Technology that the test data issued by the media was inconsistent with the actual situation of the product. During the same period, the company also sent the product to the same testing organization and did not detect the above problem.
According to reports, on March 31, the Guangdong Provincial Association of Indoor Environmental Hygiene Industry, the Chinese Academy of Sciences of the Chinese Academy of Sciences (professional third-party testing agency under the Chinese Academy of Sciences), and the "True Lab" under the umbrella of Pacific Internet, sold well to third-party e-commerce platforms. The air purifier carried out a quality survey. The results showed that the measured values and nominal values of the four numerical particulate matter CADR, formaldehyde CADR, and maximum noise of the mill air purifier 2 were significantly different.
According to the “Truth Lab”, from the measured results, the CADR of millet air purifier 2 is far from the brand name of the factory, which is only 60% of the latter. The lower formaldehyde CADR and formaldehyde purification efficiency description Millet air purifier 2's formaldehyde filtration capacity is very poor, formaldehyde CADR suspected false labeling issues require consumers to pay attention.
In response to the above test results, an air purifier industry official who declined to be named said in an interview with ChinaNet.com: 'Currently, before the products are on the market, manufacturers often choose to submit new products to major professional testing centers for testing. Home Appliances Institute, Shanghai Metrology Institute, etc., and in the sales process with the help of the certification authority's certificate to promote sales. 'The above industry sources also said that if the manufacturer's product value of the virtual standard is true, it is bound to be subject to quality inspection and the business sector Punishment.
As for the problem of scalar values of air purifiers, the reporter found out on the search site. On March 11th this year, CCTV’s “Weekly Quality Report” reported that 13 FUU air purifiers were tested and 11 PM2 products were found. 5 CADR is less than 60% of the nominal value, and all sampled FFUs have a CADR of 30% of the highest nominal value.
In June 2015, there were also media reports that the Beijing Municipal Bureau of Industry and Commerce had violated the principles of honesty and credit in the production and sales process of some operators, falsified the standards, and exaggerated the values of air purifiers and water purifiers, resulting in a total of 183 Ten thousand yuan ticket.
