An American expatriate in Delhi, Kristen Fischer, shared practical strategies for managing severe winter air pollution. Her Instagram video highlighted the significant difference in air quality between outdoors (AQI 210) and indoors (AQI near 50) due to air purifiers. Fischer's family limits outdoor exposure during peak pollution months, typically November to January, and prioritizes clean indoor air, especially during sleep. She noted that Delhi's air quality improves significantly outside of this seasonal crisis.
