How to fight extreme AQI smog with air purifiers, plus our top picks
When outdoor AQI surges into the toxic 400 range – which is the case for most of the major urban centers in the Northern Indian belt in November 2026 – basic room air cleaners simply can’t keep up. Clearing dense, hazardous smog, packed with micro-fine PM2.5 particles, chemical fumes, and volatile organic compounds (VOCs), requires specialised machinery equipped with massive clean air circulation and heavy gas filtration.
Hence, your regular PM2.5 certified air purifiers simply won’t be enough to keep your living rooms within safe limits when the outside air is ranking at over 400 AQI points.
