摘　　要：目的观察低温等离子体空气消毒机对空气中细菌和病毒气溶胶的灭活效果。方法使用气溶胶发生器在密闭气溶胶暴露柜内分别发生细菌和病毒气溶胶,采用六级Andersen采样器采集柜内空气,评价该空气消毒机对人工发生的细菌和病毒气溶胶的灭活效果。结果该低温等离子体空气消毒机对金黄色葡萄球菌、藤黄微球菌和噬菌体Phi X174气溶胶的净化效率(除菌率)分别为99.98%、99.98%和99.95%。结论该低温等离子体空气消毒机对密闭空间内空气中细菌和病毒气溶胶灭活效果较好。Objective To observe the purification efficacy of a non-thermal plasma air cleaner against bacterial and viral aerosol. Methods Bacterial and viral aerosol were generated by an aerosol generator in a sealed aerosol chamber. The air was sampled by six-grade Andersen sampler and the purification efficacy of the complex type air cleaner against bacterial and viral aerosol was evaluated. Results The clean efficiency of the low temperature plasma air cleaner against Staphylococcus aureus,Micrococcus luteus and phage Phi X174 aerosol was 99. 98%,99. 98% and 99. 95%,respectively. Conclusion The clean efficiency of the low temperature plasma cleaner is good against bacterial and viral aerosol in closed space.
