Intensifying air pollution has engendered growing public health concerns due to its broad and adverse effects on humanity. As a result, the development of air filtration technologies has received increased attention as a practical and promising solution. Till now, many efforts have sought to advance air filtration technologies to overcome the trade-off relationship between filtration efficiency and pressure drop. This review discusses recent progress in air filtration technology with respect to two distinct strategies, the first about optimizing filter structure and then on enhancing electrostatic interaction. Three different structure-based techniques are reviewed, including fiber morphology modification, component hybridization, and multilayer stacking, and then three interaction-based approaches that operate by imposing charge are discussed, such as induction charging, triboelectric charging, and corona charging. Furthermore, two types of active air filtration applications are comprehensively discussed as interaction-based approaches. The review concludes by discussing the current limitations and future prospects of air filtration technologies, including applications beyond air purification.

由于空气污染对人类的广泛不利影响，加剧的空气污染已引起越来越多的公共卫生关注。结果，作为实用且有希望的解决方案，空气过滤技术的发展受到了越来越多的关注。到目前为止，已经进行了许多努力来发展空气过滤技术，以克服过滤效率和压降之间的权衡关系。本文就两种不同的策略讨论了空气过滤技术的最新进展，首先是优化过滤器结构，然后是增强静电相互作用。综述了三种不同的基于结构的技术，包括纤维形态改性，组分杂交和多层堆叠，然后讨论了三种通过施加电荷进行相互作用的基于相互作用的方法，例如感应充电，摩擦带电和电晕充电。此外，作为基于交互的方法，对两种类型的主动空气过滤应用进行了全面讨论。审查总结了空气过滤技术的当前局限性和未来前景，包括空气净化以外的应用。
