Air purifier or explicit formaldehyde removal rate

In order for consumers to no longer be troubled by advertisements with a “99.9% removal rate,” the air purifier industry alliance held an industry self-discipline conference yesterday. It is reported that in the future, the mainstream brand of air purifiers in the city will be in the form of labeling, clearly inform the product area, PM2.5 removal performance and energy efficiency evaluation. At the same time, plans to increase the formaldehyde removal rate and purification life of the two indicators during the year, so that consumers can be based on the same test data obtained under the premise, based on their own choice of products.

"The removal rate of 99.9% is a bit alarming." A representative of a Suzhou purifier manufacturer who attended the meeting yesterday was also sighed at the fact that many purifiers in the market generally claim formaldehyde and particulate matter purification data.

Yesterday, the reporter went to a large home appliance store in Zhongshan Park, where various brands of purifiers are on the spot. At some counters, salespeople enthusiastically explain the machine's performance to consumers, but it is difficult to say clearly how the data results are derived. In fact, this kind of data seems very gratifying, but there is a common problem that most of the similar slogans on the market do not mention the detection prerequisites derived from the data, including what kind of testing standards are used. How long does it take to detect the environment, how long it takes to detect it, and so on? "For example, the results of the removal rate of a machine after 8 hours of use and after 12 hours of use are incomparable." The representative told reporters that, in fact, some purifiers are removed in a suitable environment. The effect of formaldehyde can reach 98%, but it takes different time. As for the 99.9% of the data, "this is also a bit exaggerated."

The Air Purifier Industry Alliance stated yesterday that the products to be marketed in the future will be uniformly labelled, and the data involved in the labeling will be tested by the third party under the same standard. Union Secretary-General Shen Hao said that it is expected that the first batch of labeled products will be listed at the end of this month. In the autumn and winter of this year, with the increase of labeling products, people can obtain more intuitive reference data during the consumption period and start the industry. Internal "shuffle."

In addition, at present, there is still a problem that the quality of service needs to be improved. Tao Ailian, deputy secretary-general of the Municipal Consumer Protection Committee, revealed that the proportion of complaints against products and services a decade ago was more than 60% and over 30% respectively, and the current number of complaints against service categories accounted for over 60%. As far as the air purifier is concerned, how to ensure that the filter and other materials can be replaced in a timely manner, including the installation of a replacement warning light on the product, etc., also require the merchant to further standardize and strengthen after-sales service.
