With the continued deterioration of air quality, the people in the health concerns of "breathing" at the same time, also greatly stimulated the air purification product sales. Some companies see the "opportunities" have entered the field of air purification, different types, different techniques of air purification products in the markets. The quality of the product in the end how? Whether to achieve the national standards? There is no exaggerated propaganda? In order to promote and standardize the domestic air purification industry sustained and healthy development, by the China clean air industry alliance, the Chinese Preventive Medicine Association of sanitary engineering branch, national quality supervision and inspection center of air conditioning equipment, China Installation Association of construction equipment and the system operation maintenance branch and other units jointly sponsored the 2014 air purification products, national inspection work has officially started. The present work is being carried out in the field sampling.

本次統檢工作于2014年6月1日至8月31日進行，歷經三個月，依據企業自愿參與原則，由國家空調設備質量監督檢驗中心對空氣凈化器（單體式、模塊式）和空氣過濾器（含空氣過濾材料）兩大類產品進行統一檢驗。

    The inspection work was conducted from June 1, 2014 to August 31st, after three months, on the basis of the corporate voluntary participation principle, by the State Quality Supervision and inspection center air conditioning equipment of air purifier (single type, modular type) and air filters (including air filter material) unified examination two categories of products.

統檢工作參照中國空氣凈化行業聯盟籌備處制定的工作流程，對確定參與統檢的企業，一律進行現場產品抽樣。封存后由國家空調設備質量監督檢驗中心參照GB/T18801-2008《空氣凈化器》、GB/T14295-2008《空氣過濾器》、JG/T294-2010《空氣凈化器污染物凈化性能測定》、JG/T404-2013《空氣過濾器用濾料》、GB21551.3-2010《家用和類似用途電器的抗菌、除菌、凈化功能空氣凈化器的特殊要求》等標準，按照《PM2.5凈化效能檢測方案》、《PM2.5一次通過凈化效率檢測方案》的規定，對產品各項指標進行檢測并出具正式檢測報告，統檢數據匯總后經專業委員會評價，按照統檢的判定原則對其產品進行分級（如圖1和圖2），其中性能突出的產品將由中國空氣凈化行業聯盟加貼相應的凈化性能標識。檢測合格后，頒發統檢合格證書。統檢結果匯總后報國家相關部委作為建筑物內PM2.5治理的技術依據。

    Inspection work in accordance with Chinese clean air industry alliance preparatory office established working process, to determine the involvement of inspection of enterprises, will be on-site product sampling. After sealed by the national air conditioning equipment quality supervision and inspection center according to GB/T18801-2008 "air purifier", GB/T14295-2008 "air filter", JG/T294-2010 "air purifier pollutant purification performance determination", JG/T404-2013 "air filter for filter", GB21551.3-2010 "household and similar electrical appliances, antibacterial and cleaning function of air purifier special requirements" standard. According to the "PM2.5 purification efficiency detection scheme", "PM2.5 once through the purification efficiency detection scheme" provisions, the products of the indicators tested and issued by the official testing report, inspection data summary after professional committee evaluation, according to the product grade to determine the principle of unified inspection (Figure 1 and Figure 2) the performance, outstanding products will be China's clean air industry alliance add purification performance identifies a corresponding. Detection of qualified, qualified certificate issued by the inspection. Inspection report the results to relevant state ministries and commissions as building summary of PM2.5 governance technical basis.
