The rapid pace of industrialization and urbanization has brought about significant environmental challenges, especially in densely populated areas where air pollution poses serious health risks. This paper conducts a comprehensive investigation into the influence of electrostatic enhancement on air filter performance, focusing on the removal of fine particles. The research addresses the critical need for effective air filtration systems due to the adverse impact of air pollutants on human health and indoor air quality. Through an extensive review of relevant literature, we present a series of parametric studies carried out by various researchers, emphasizing developments in electrostatically enhanced filtration methods, hydro-charged filters, and electric field-assisted cyclones. These studies delve into the challenges of maintaining high filtration efficiency while optimizing operational parameters. In light of this context, our study aims to explore the advantages of electrostatically enhanced air filters for fine particle removal through rigorous Computational Fluid Dynamics (CFD) simulations. Our investigation delves into the influence of electrostatic enhancement on filtration efficiency, the relationship between electrostatic field strength and filtration improvement, the impact of applied voltage and discharge wire position, and the effects of varying inlet velocity. The findings establish a direct connection between electrostatic enhancement and improved filtration efficiency, providing insights into optimal operational parameters. This study underscores the significance of fine- tuning electrostatic parameters to attain superior air filtration results, contributing to cleaner indoor air and enhanced environmental sustainability.
