Air Pollution Control Using Ionizer

Rapid urbanization and vehicular growth have significantly increased roadside air pollution levels, particularly particulate matter such as PM10 and PM2.5. Prolonged exposure to these pollutants causes serious respiratory and environmental health issues. This research presents the design and development of a low-cost roadside air purification prototype using ionizer technology. The developed system consists of a DC fan for air intake, a negative ion generator for charging dust particles, Whatman filter paper for particulate filtration, and activated carbon for harmful gas adsorption. The ionizer electrically charges suspended particles, making them easier to trap within the filter media. The prototype was tested under semi-outdoor conditions, and visible particulate reduction was observed within the filtration chamber. The system operates on a 12V DC supply and consumes low power. The developed model demonstrates potential application for small-scale roadside pollution control and can be further enhanced for large-scale deployment
