请看例句：

One-quarter of air purifiers sold on the domestic market are substandard, according to the General Administration of Quality Supervision, Inspection and Quarantine.

国家质检总局称，国内市场上销售的空气净化器中，有1/4的产品不合格。

今年上半年(in the first half of this year)，国家质检总局(the General Administration of Quality Supervision, Inspection and Quarantine, AQSIQ)对56家企业生产的61批次空气净化器(61 batches of air purifiers)进行抽查，发现14家企业生产的15批次产品不合格(15 batches of products were substandard)，产品抽查合格率(qualification ratio)为75.4%。广东净霸、上海新松电子等国内企业生产的净化器因甲醛(methanol)净化能效、噪音不达标准被列为不合格产品。

这是国家质检总局首次针对空气净化器进行全国性质量检查(this is the first time that the AQSIQ has organized a national quality inspection aimed at air purifiers)，覆盖了多数业内知名品牌(cover most well-known brands available in the industry)，抽查企业数将近全国生产企业总数的1/5。

近年来，随着人们对空气净化器需求的增长，制造商的数量也随之有所增加(with increasing demand for air purifiers in recent years, the number of producers has also risen)。今年上半年，中国空气净化器总销量为450万台，比2015年同期增长了58%。
