Delhi has been placed under GRAP Stage 3, a severe-response tier activated when winter pollution spikes, which triggers strict measures: bans/curbs on construction and demolition, restrictions on older diesel vehicles (BS-IV and below), limits on diesel generators and the move of younger school classes to hybrid or online teaching to reduce exposure. Those emergency steps are meant to cut fresh emissions quickly, but they don’t clean indoor air, and with particulate readings at hazardous levels across the NCR, households need practical defences right away. A reliable air purifier with true HEPA filtration, a CADR matched to room size, activated-carbon for gases, low noise and affordable filter replacements will make the most immediate difference. We have reviewed five models that balance filtration performance, running cost and real-world usability so you can pick one that actually helps while authorities tackle the smog.
