Solar Air: A Solar-Powered Air Purification System

Air pollution poses a significant threat to public health, with millions of people exposed to harmful pollutants, particularly in urban and industrial areas. Conventional air purification systems often rely on electrical power or chemical processes, leading to increased energy consumption and environmental impact. To address these issues, this research presents Solar air, a solar-powered air purification system that utilizes renewable solar energy to purify indoor and outdoor air. The system employs a combination of photovoltaic-powered fans and advanced filtration materials, including activated carbon and HEPA filters, to capture particulate matter, volatile organic compounds (VOCs), and other harmful pollutants. Field tests demonstrate that Solar air significantly reduces airborne contaminants, with an average removal efficiency of 90% for particulate matter (PM2.5) and a notable reduction in indoor VOC levels. The system's performance is closely tied to solar intensity, yet it operates with low maintenance and minimal energy costs.
