Overview
- A Hindustan Times week-long exercise recorded indoor PM2.5 typically in the 200–300 µg/m³ range at an AIIMS ward and a Rohini school, with spikes above 400 µg/m³, while a home room with a purifier fell to 18 µg/m³.
- AIIMS medical superintendent Dr. Nirupama Madan said experts have been engaged to design measures and that a pilot to install HEPA filtration in general wards is likely in the coming months.
- Over 100 senior doctors at a Delhi session warned that polluted indoor air is raising infection risks and slowing recovery in healthcare settings.
- A German air scientist at the event said floor-standing purifiers often underperform in busy hospitals and recommended ceiling-mounted systems for better circulation in critical zones.
- Delhi ministers outlined a multi-year airshed plan that includes expanding buses and Metro, stronger dust and construction controls, and a phased rollout of classroom purifiers, while experts cautioned indoor fixes cannot substitute for cleaner outdoor air.
