Many studies have found that the concentration of fine particulates in the atmosphere has increased. In particular, when using the bus, the situation in which people are exposed to relatively high concentrations of fine particulates is increasing. The purpose of this study is to reduce exposure to these potentially harmful particulates by introducing open shelters at outdoor bus stops. In order to use it as an outdoor fine particulates reduction device, a brush filter using electrostatic force (EF) was used on an experimental scale and the generation of electrostatic force, according to the material, was examined. As electrostatic force was generated, the fine particulates collection performance was about 90% efficiency. In addition, it was confirmed that the efficiency of each particle size was improved by 57% through structural improvement. Finally, through experimentation, it was confirmed that the brush module can be used for about 70 days.
许多研究发现，大气中的细颗粒物浓度有所增加。特别是在乘坐公共汽车时，人们接触到相对高浓度细颗粒物的情况正在增加。本研究的目的是通过在室外公共汽车站引入开放式候车棚来减少对这些潜在有害颗粒物的暴露。为了将其用作室外细颗粒物减少装置，在实验规模上使用了一种利用静电力（EF）的毛刷过滤器，并根据材料检查了静电力的产生情况。由于产生了静电力，细颗粒物的收集性能达到了约 90%的效率。此外，通过结构改进，确认了每个粒径的效率提高了 57%。最后，通过实验，确认毛刷模块可以使用约 70 天。
