Abstract: Air pollution is a critical global challenge, particularly in urban and industrial corridors. This study presents the design, fabrication, and performance evaluation of an autonomous solar powered air pollution control system. The prototype integrated a 100 W photovoltaic (PV) panel, a 12V 20Ah battery, and a multistage filtration unit consisting of a pre-filter, HEPA filter, and activated carbon filter. The experimental results indicate a maximum solar power generation of 38.8 W and a battery backup time of 8.5 h. The system achieved a significant reduction in pollutants, with average efficiencies of 70.4% for PM2.5 and 68% for PM10. Economic analysis shows a 40–60% reduction in the total project cost compared to commercial alternatives, demonstrating the feasibility of the system for small-scale industrial and roadside applications.
