摘　　要："史上最严"的控烟条例《北京市控制吸烟条例》正式实施,现行空气净化器性能测试中以香烟烟雾作为颗粒物污染源的标准受到挑战;加之燃香源颗粒物净化手段少有讨论。故以室内燃香替代香烟作为PM2.5的污染源,在环境实验舱内通过对市售净化器性能指标CADR进行测试,证明燃香可产生持续且稳定的颗粒物,可以替代香烟作为颗粒物污染源。燃香全程净化效果试验表明:在一根燃香的过程中时,开启净化器可保持采样点全程优质的空气质量;使用两根燃香时,采样点高度差异可导致明显的浓度差异,建议使用中考虑净化器摆放高度。The most rigorous ban on smoking in the history took effect in Beijing in 2015. The smoke from cigarette burning is used as particulate matters in performance testing of air cleaners. In addition,the study on purifying incense-burning smoke is scarce. So incense burning,instead of cigarette,was used in CADR testing. Smokes from incense burning were steady and it could be used as a source of PM2. 5. Results showed that air quality at sampling spots kept excellent by air cleaners in the whole period of a burning incense; sample point height difference could lead to obvious concentration difference in the period of two burning incense,so the air cleaners placed height should be considered during use.
