Delhi pollution: Grey skies & red eyes outside, air purifiers only stop-gap aid inside
Delhi residents are turning to air purifiers for relief from hazardous air pollution, but experts warn they are a temporary and potentially problematic solution. While these devices can filter out PM2.5, they can’t address rising carbon dioxide levels in enclosed spaces, posing health risks, especially during sleep. Experts recommend limited use, ventilation, and masks as more viable strategies.
