According to Ma Dejun, secretary general of the National Standardization Technical Committee of Household Electrical Appliances, compared with the old version of the 2008 edition, the newly revised national standard of air purifiers clearly emphasizes the two indicators of clean air volume and cumulative purification volume. The amount of clean air is CADR. The value is used to measure the purifying capacity of the air purifier, and the accumulated purifying amount refers to the total amount of pollutants that are removed when the amount of clean air is reduced to half of the initial value during the air purifier working process. The performance of the device was measured.
That is, the air purifier should not only purify the indoor air in a short period of time, but also maintain this level of purification for a long time. “In the past, some brands of purifiers usually displayed their purifying effect in a small confined space, but in fact, this is not referenced for normal family use.â€
According to the results of this release, Panasonic, Samsung, Philips, Daikin, etc. have all been shortlisted, and Amway's purifiers, which are known for their health products and nutritional products, are also on the list.
However, domestic brands only accounted for a small part of them, including Haier, Yadu, etc., which have been on the market for a long time. Haier, Yadu, etc. are not on the list. Some purifiers launched by Xiaomi and other internet brands are not included.
However, according to relevant sources of the China Household Electrical Appliances Research Institute, the first batch of products not on the list does not necessarily mean that the new national standard has not been reached. This test will be carried out in phases. “A batch of batches will be announced and purchased for consumers. Air purifiers provide references."
It was learned from the Institute of Testing Technology of the China Household Electrical Appliances Research Institute that after the introduction of the new national version of the air purifier, there are currently 11 models of air purifiers of 10 brands that have passed the new national standard test. It is worth noting that under the background of the new national standard on product certification standards have been greatly revised, the brand of air purifier tested by the new national standard is mostly foreign brands, and domestic brands only occupy a small part.
