空气净化器对室内有害气体净化效果的研究

Research on tbe Air Cleaner's Purification Effect on Indoor Toxic Gas

采用“清洁空气量”（ＣＡＤＲ）作为评价指标，对四种国产空气净化器去除有害气体的性能进行测试。结果表明，该四种空气净化器对ＳＯ２、ＮＯｘ、ＨＣＨＯ等有害气体均有一定的吸附效果。

This essay uses CADR(clean air delivery rate)as an evaluation index. In order to remove toxic gas,we have made a performance test for four types of air cleaners made in China. The result shows that these air cleaners can absorb toxic gas such as SO2,NOx,HCHO to certain extent.
