【财经看点】《空气净化器》标准明年3月1日实施

A new set of national standards for air purifiers will come into force next March. Air purifiers have become one of the hot products among consumers amid the severe air pollution in China. The new standards will have a focus on particulate matters like PM 2.5, the main pollutant for China's lingering smog. Ma Dejun is the head of the authority that is responsible for setting up the new standards. "In the new standards, we have adopted some latest international metrics to evaluate the quality of an air purifier, like CADR or Clean Air Delivery Rate. There are also original standards like CCM or Cumulate Clean Mass and the life expansion of the purification. Apart from these core indicators, we also have standards for efficiency and the noise levels of the machine." The new standards team started to solicit opinions among the public and industry insiders at the end of last year. They still need to be ratified by a higher authority before taking effect. The country's current standards for air purifiers were launched in 2002. But the standards became out-dated as the country started to see worsening air pollution in recent years.
