After the SARS in 2003, China has strengthened the implementation of air quality in indoor public places. How to effectively reduce the inhalation of particulate pollutants and prevent the spread of respiratory diseases is a current environmental problem.
传统的净化方式采用过滤器除尘法， 通过不同直径滤材可截流 相对应的颗粒物达到净化效果， 对室内人活动产生的污染颗粒、 细 菌、 病毒和建筑物的污染物难以有效控制。 过滤器的维护和更换对 其延续有效性、 避免过滤单元中深层污染物的溢出和夹带入空气起 了重要的作用； 但维护费用高。 积尘给微生物的繁殖提供了条件， 增加运行期间污染物散发的可能性： 国际空气品质标准 ISO/DIS16814视其为污染源。 1个细菌每 20分钟裂变 1次 8小时可达 1677万个。 可以通过增加过滤纤维的厚度和减小纤维直径， 以便增 加纤维填充率提高净化率； 但是同样增加了阻力和能耗。 The traditional purification method adopts the filter dust removal method, and the particles corresponding to the different diameter filter materials can be used to intercept the corresponding particles to achieve the purification effect, and it is difficult to effectively control the pollution particles, bacteria, viruses and building pollutants generated by indoor human activities. Maintenance and replacement of the filter plays an important role in its continued effectiveness, avoiding the spillage of deep contaminants in the filter unit and entrainment of air; however, maintenance costs are high. Dust builds conditions that allow microbial growth to increase the likelihood of contaminant emissions during operation: International air quality standards ISO/DIS16814 treats them as sources of contamination. One bacterium can be fissioned every 20 minutes, and 8 hours can reach 16.77 million. The cleaning rate can be increased by increasing the thickness of the filter fibers and reducing the fiber diameter to increase the fiber filling rate; however, the resistance and energy consumption are also increased.

Therefore, subway ventilation cannot be measured by a single standard. For example, spring and autumn are 100% ventilation and air conditioning in winter and summer. In the case of 90% of the circulating wind 10% ventilation is very different. Commonly used air purification systems often fail to meet the requirements.
