分析了一般通风用过滤器的作用和选择原则，对比了我国和欧盟的测试标准 GB／T 14295-2008和 EN 779-2012。利用测试台对国内两种过滤器（A，C）和国外某产品 B 进行性能测试，获得了材料厚度、过滤器阻力、过滤效率及微观形貌。通过品质因素分析，发现过滤器A 对细颗粒物的品质因素最优，达到0．102，其滤料具有低阻高效的特征，在一定的支撑力下，可以提供更大的三维空间，提高容尘效率与拦截效率。过滤器 B 对细颗粒物的品质因素为0．077，原因是滤料内部均匀分布，能提供较高的过滤效率。过滤器 A 的工艺与过滤器 B 的工艺相结合是未来技术发展方向。

Introduces the function of general ventilation air filter and its selection principle,and compares the test methods between GB/T 14295-008 in China and EN 779-2012 in EU.Performs the performance test among air filters A,B and C with the test rig.Obtains the thickness,resistance,filtration efficiency and microscopic morphology.With the analysis of quality factor,the performance of filter A is the best for PM2.5,which reaches 0.102.Filter A has the characteristic of low resistance and high efficiency,where the dust holding capacity and interception efficiency are increased by the enlarged three-dimensional space with the strong holder.The quality factor of filter B reaches 0.077.Filter media B has the uniform distribution of fibers,which can increase the efficiency.The combination of the process for material A and material B should be the future trend.
