• The air pollution crisis has spread to NCR cities like Noida, Ghaziabad, Gurugram, and Faridabad, mirroring Delhi's toxic air.
• Cities in Uttar Pradesh (Ghaziabad, Noida, Bulandshahr) and Haryana (Panipat, Hisar) also report "poor to severe" air quality.
• Even traditional clean-air getaways like Dehradun are experiencing "poor" AQI, reaching 260-300.
