摘　　要：目的:了解医用空气净化消毒器以静电吸附和过滤器过滤对空气净化消毒的效果。方法:采用气雾染菌法和现场试验法进行试验观察。结果:该医用空气净化消毒器颗粒物净化效率为75%;对体积为90 m3的空间开机作用30 min,颗粒物去除率为93.3%;对体积为20 m3气雾室空气中人工污染白色葡萄球菌开机作用30 min,杀灭率为99.98%;现场试验证明,该医用空气净化消毒器开机作用60 min,对体积为90 m3室内空气中自然菌的各次消除率均达到90%以上。结论:该医用空气净化消毒器,对实验室和现场室内空气的颗粒物净化效率、消毒效果均达到规定标准,具有较好颗粒物去除和杀菌效果。Objective：To observe the efficacy of the medical air cleaner with static absorbing and filtering apparatus in disinfection and purification of indoor air. Methods：Aerosol bacterial contamination method and field trial method were used to carry out experimental observation. Results：The particulate matter purifying efficiency of the medical air cleaner was 75% and the removal efficiency of particulate matter in 90 m^3 room was 93. 3% after the operation of the medcal air cleaner for 30 min. The operation of the medcal air cleaner for 30 min could eliminate 99. 98% of staphylococcus albus in air of 20 m^3 aerosol chamber. The field trial demonstrated that the decay rates of natural bacteria in air of 90 m^3 room were over 90% after disinfection for 60 min. Conclusion：The medical air cleaner is very effective in eliminating particular matter and bateria of indoor air.
