        abstract = {The rapid growth of urbanization and industrialization has significantly increased air pollution levels, creating an urgent need for an efficient and reliable monitoring and active remediation system to ensure a healthy urban environment. The air quality in dense urban areas is highly sensitive to variations in pollutant concentrations, such as particulate matter (PM2.5,PM10), carbon monoxide (CO), nitrogen oxides (NOx), and other toxic gases. Improper monitoring of these parameters can lead to severe public health crises, environmental degradation, and long-term climate impacts. This project presents the design and implementation of a Smart Air Pollution Monitoring and Filtration System for urban areas integrated with essential components such as a multi-gas sensor array, particulate matter sensor, active filtration unit, Internet of Things (IoT) communication module, and a standalone solar power management system for accurate real-time monitoring and proactive air remediation. The proposed system uses a combination of high-efficiency particulate air (HEPA) and activated carbon filters as the primary air scrubbing mechanism due to their proven ability to remove a broad spectrum of airborne pollutants. A dedicated microcontroller-based control unit is employed to continuously monitor local air quality parameters and maintain hazardous pollutant concentrations below critical limits. The gas sensors measure specific pollutant levels to prevent dangerous human exposure and detect sudden pollution spikes. The filtration unit is activated automatically based on real-time data to scrub the surrounding air when thresholds are exceeded. Additionally, the IoT module transmits the collected data to a cloud platform for remote logging, historical analysis, and public alerting. The developed prototype is energy-efficient, scalable, and suitable for high-traffic intersections, bus stops, and other urban hotspots. By integrating comprehensive environmental sensing with automated, localized filtration and real-time data transparency, the system significantly improves urban air quality monitoring resolution and direct respiratory protection. This project contributes to enhancing urban environmental resilience while promoting sustainable and health-conscious smart city development solutions.},
