air purifier

請看例句：

One-quarter of air purifiers sold on the domestic market are substandard, according to the General Administration of Quality Supervision, Inspection and Quarantine.
國家質檢總局稱，國內市場上銷售的空氣凈化器中，有1/4的產品不合格。

今年上半年(in the first half of this year)，國家質檢總局(the General Administration of Quality Supervision, Inspection and Quarantine, AQSIQ)對56家企業生產的61批次空氣凈化器(61 batches of air purifiers)進行抽查，發現14家企業生產的15批次產品不合格(15 batches of products were substandard)，產品抽查合格率(qualification ratio)為75.4%。廣東凈霸、上海新松電子等國內企業生產的凈化器因甲醛(methanol)凈化能效、噪音不達標準被列為不合格產品。

這是國家質檢總局首次針對空氣凈化器進行全國性質量檢查(this is the first time that the AQSIQ has organized a national quality inspection aimed at air purifiers)，覆蓋了多數業內知名品牌(cover most well-known brands available in the industry)，抽查企業數將近全國生產企業總數的1/5。

近年來，隨著人們對空氣凈化器需求的增長，制造商的數量也隨之有所增加(with increasing demand for air purifiers in recent years, the number of producers has also risen)。今年上半年，中國空氣凈化器總銷量為450萬臺，比2015年同期增長了58%。
