对市售某空气净化(或清新)机进行了性能和现场效果测试。发现该产品的负离子发生量较高(约10~6个/cm~3),但不稳定,现场测定的空气中负离子几未测得。对TSP、细菌总数的净化率均较低。说明该类产品对空气无明显的净化效果。
A commercially available air purification (or fresh) machine performance and field performance testing. It was found that the anion of this product was high (about 10 ~ 6 / cm ~ 3), but it was not stable. Some negative ions in the air were not measured in the field. For TSP, the total bacterial purification rate is low. Description of such products on the air no significant purification effect.
