Delhi’s monthly average air quality index (AQI) for October is 166, the lowest October average in eight years, according to a statement cited by multiple outlets. The figure marks an improvement compared with recent years and is based on the monthly average AQI values reported for October.
Outlets that covered the story frame it as a notable drop in pollution levels for the month. Business Line and NDTV provide the full year-by-year comparison, showing that October 2025 (223) is higher than 2024 (234) and lower than several earlier years, with the lowest cited point being 166. Swarajya also highlights the “cleanest October” phrasing while focusing on the same headline statistic of 166.
While all outlets converge on the central AQI number and the “lowest in eight years” claim, their presentation differs mainly in emphasis—some stress the improvement and “cleanest” framing, while at least two explicitly include the historical AQI range cited from the ministry statement.
