Air purifier lacks uniform standards

With the frequent occurrence of fog and haze around the city, the air purifier market is booming. However, due to the lack of corresponding national standards, air purifier products are mixed. Recently, the Shanghai Bureau of Quality Supervision spot-checked 20 batches of air purifier products. The results showed that some of the products were exposed on the areas not covered by the mandatory regulations of the country and the energy efficiency level. There were standard loopholes and exaggerated products. Suspected of efficacy.

The local standard of the air purifier “perfunctory” has been tested. There are seven batches of 20 batches of samples that have no nominal application area at all, and there are nine batches of samples that are nominally applicable, but the measured values ​​are far less than the nominal results. Among them, "YADU" air purifier produced by Suzhou Yadu Environmental Protection Technology Co., Ltd. (specification model: KJG200AS, production batch number: 2012.5/SYJB06764) and "PHILIPS" air purifier produced by Philips (China) Investment Co., Ltd. (Specifications Model No.: AC4025, Production Lot No.: 2013.3.7/6947265403150), "Kangrui" Air Purifier produced by Shanghai Huaming High-tech (Group) Co., Ltd. (Specification Model: KR-100, Production Lot No.: 2012.12/6921267010110), Shenzhen "Heathlead" air purifier produced by Hong Kong Environmental Protection Technology Co., Ltd. (Specifications: EPI211-2B, production lot: HLD120500399), "BODNER & MANN" air purifier produced by Shenzhen Kanghong Environmental Protection Technology Co., Ltd. (Specification model: EPI232-2 , Production batch number: 2010.3.6) The measured usage area of ​​five batches of air purifiers is half or even half of the nominal value.

The air purifier has a hidden standard of cleanliness and lack of uniform standards. The reporter found that the air purification effect detection unit of the product introduction can be described as all sorts of colors, but no one is the test result of relevant quality authorities such as quality supervision. The air purifiers provided by the United States are qualified certificates issued by the Chinese Center for Disease Control and Prevention; those issued by the Philips air purifiers are certified by the local quality supervision department of the assembly plant; and the products issued by Sharp are obtained from the United States. Association testimony...

These air purification certifications and product certifications are marked with the line “The monitoring data is taken from normal humidity and is operated at a high speed for more than 60 minutes in 1 cubic meter of space”. Obviously, if this monitoring result is applied to the actual home environment, its effect is still worthy of doubt.

The reporter learned from the quality supervision department that air purifier products only need to pass the safety and quality certification, and the GB/T18801-2008 “Air Purifier” standard revised at the end of 2008. Functional certification is not within the scope of national compulsory certification.

Song Guangsheng, director of the National Indoor Environment and Indoor Environmental Protection Product Quality Supervision and Inspection Center, said in an interview that the industry should not reach a consensus on what standards should be met after air purification.

Expert ozone release is harmful to human body According to indoor air quality requirements, the indoor ozone concentration can not be higher than 0.16 milligrams per cubic meter. The damage to human body exceeding the limited value of ozone has been confirmed.

Fu Haidong, deputy director of the Department of Environmental Health at Fudan University, explained: “In the atmospheric stratosphere, ozone is a thing that helps us to block UV rays that are good for human health. But in the troposphere of our lives, the ozone in the atmosphere acts as a highly oxidizing agent. Sex gases can damage people's respiratory epithelial cells and pose a threat to the health of the respiratory system. Those suffering from respiratory diseases such as asthma should be particularly careful about exposure to ozone."
