Air purifiers can indeed play a role in improving the quality of life of consumers, but there has always been a problem of over-promotion in the domestic net market. Hanston's purification experts say 'due to the lack of uniform mandatory standards in our air purification market, And the excessive publicity of the air purifier brand has caused serious illnesses against consumers.
The market is booming, and the strong offensive of various brands in publicity has also brought many troubles to consumers. Various selling points are exaggerating the 'hardest hit areas' that promote misleading consumption. And those purifying and sterilizing most consumers The data is not so standardized. Take a Japanese brand purifier as an example. The manufacturer said that the formaldehyde reduction rate after use is 94.7%. In fact, this data is run by a bioanalytical testing center using a purifier in a cubic cubic meter of confined space. Measured after 8 hours. The so-called 98% PM2.5 removal rate is also measured in a dedicated 'laboratory'.
Another domestic brand product, the advertisement said that the formaldehyde purification rate reached 99.71%, and the data was also measured by a building environmental testing center using a specific test method. According to the CCTV Weekly Quality Report, the market is selling well. In the purifier products, some of the purification efficiency of PM2.5 and formaldehyde can not reach the value claimed by the merchants, especially for the purification ability of formaldehyde, which is far from the claimed 99% purification effect.
At present, there are no mandatory national standards for air purifier products, so some products implement recommended national standards, while others implement their own corporate standards. The air purifier market has excessive propaganda and confusion concepts. Mainly because there is no uniform mandatory national standard for its products, so the so-called purification performance of different purifier products is basically not comparable, for example, it is claimed that the formaldehyde purification effect can reach 98%, and some purifiers only need one or two. It can be reached in an hour, while some purifiers take more than a dozen hours.
Due to the lack of uniform mandatory standards, it is difficult for law enforcement agencies to judge the quality of the purifier products. Although it is tested according to the national recommended standards, it can be proved that some purifier products can not achieve the claimed purification effect, but The national standards for the main indicators of purification are not uniform or mandatory, so it is difficult to determine that these purifier products are unqualified.
