How Outdoor Pollution Enters Homes and Improves Air Purifier Efficiency in Delhi
Delhi's outdoor air pollution, including PM2.5 particles from vehicles and industry, infiltrates homes through open windows, doors, ventilation systems, and small structural gaps. Indoor sources like cooking, incense, and smoking also contribute to poor air quality. Closing doors and windows helps air purifiers work more effectively by reducing incoming polluted air, allowing filters to clean indoor air faster and last longer. Sealing gaps with weather strips or draught stoppers further improves indoor air quality during high pollution periods.
