Delhi's air pollution has everyone googling 'PM2.5'

India Nov 24, 2025

Delhi's air quality is so bad right now that "PM2.5" has become one of the city's hottest Google searches.
With barely any "good air days" this year and over 245 days marked as unsafe, people are scrambling for HEPA filter air purifiers—which are now in short supply.

Air worries take center stage in Delhi and Haryana

Google Trends shows that folks in Delhi and Haryana are searching about air quality more than anything else, even beating out topics like new labor laws or stock news.
All this buzz highlights the seriousness with which the public is taking health risks from pollution—and the increasing concern about the need for better, real-time updates on air quality.
