摘　　要：空调过滤网是影响室内空气质量的重要因素。比较了两种类型空调过滤网(静电过滤网和普通过滤网)对室内空气质量的净化效果,以及空调工作一段时间后,其过滤效果的变化。结果显示,空调过滤网可以有效地过滤室内可吸入颗粒物和生物活性粒子,但是对挥发性有机化合物过滤效果较差,对CO2和NO2没有明显效果。静电过滤网滤菌滤尘效果优于普通过滤网。长期不清洗过滤网,其过滤效果会降低,并且会造成严重的空气污染。Air conditioner filter plays an important role in determining indoor air quality. The efficiency of two kinds of air filters （electrostatic filter and ordinary filter） was examined in this study. The efficiency between clean and dirty ordinary filters was also compared. Results showed that both types of air filters could effectively remove particulates and bacteria, but the efficiency on TVOC was relatively low. Besides, they showed little effect on filtering CO2 and NO2. Overall, an electrostatic filter was more efficient than an ordinary filter. Dirty ordinary filter showed a negative impact on the performance of the air conditioning system, and was even a pollutant source.
