Empty net new standard: no more than 400 cubic meters of particulate matter per hour

The reporter recently learned from the 2017 two net summit held by Suning Tesco in Xi'an District. At present, Suning Tesco and Zhongyikang jointly launched, and more than ten mainstream airspaces such as Cobos, Lake, Yadu, Philips, Supor and Midea. The net brand participated in the creation and release of the empty net 7-star certification standard. The new 7-star certification has a more accurate quantitative standard for empty net products, which can be compared by consumers when purchasing later.

At the moment, the empty net products have become the urgent needs of the Chinese people, but the empty net industry is also mixed. Consumers have a crisis of confidence in the purchase of air purifiers. Since the introduction of the new national standard, chaos has been curbed, but consumers are buying for the net. Still have doubts.

In response to this industry chaos, the relevant state departments have introduced a new national standard in March 2016. A number of products that do not meet the standards, are of inferior quality, have poor production technology, and are not in service are washed out. The number of empty net brands is more than 700. The number has dropped to more than 400, which has effectively promoted the development of the empty net industry. However, the current consumer demand for empty net products has surpassed the definition in the new national standard and requires a clearer and easier to understand empty net purchase standard. Under this circumstance, based on the new national standard, Suning Tesco and China Yikang, China Quality Inspection Association and various air mainstream brands have launched star certification standards for seven indicators.

Experts said that the significance of the new national standard is to solve the "threshold" of the performance of air purifiers, which belongs to the basis and preconditions of the current "grading standards", while the star-rated certification standards jointly introduced by home appliance manufacturers will take the empty net products from all directions. Grading, including the amount of clean air per hour for particulate contaminants, the amount of clean air per hour for formaldehyde removal, etc., all have a quantifiable standard. The seven-star certified air-net products can meet the highest standards of the new national standard on these indicators, and have guiding significance for ordinary consumers.

The reporter found that among the two indicators of particulate matter and formaldehyde that consumers are most concerned about, the seven-star standard issued by home appliance manufacturers requires ≥400 cubic meters per hour to remove particulate pollutants, except for formaldehyde, the amount of filtration per hour should be ≥200 cubic meters. . At the same time, the cumulative purification amount of particulate matter and formaldehyde is defined. Except for the pollutants, the particulate matter must be greater than 12000mg, and the cumulative purification amount of formaldehyde must be greater than 1500mg. Under such standards, the reporter found that in a 5 square meter room, the air purifier can reduce the PM2.5 from 100 to 18 in less than 2 minutes.
