Air quality can improve within a few hours to several days after a pollution spike, depending on weather conditions and emission sources.

Estimated Duration: 1 days

The time it takes for air quality to recover after a pollution spike depends on factors like wind, rain, and the reduction of pollutant emissions. Natural processes like dispersion and chemical reactions help clear pollutants, but persistent sources or stagnant weather can prolong poor air quality. Urban areas with high traffic may see faster improvements if emissions drop, while industrial regions may take longer. Monitoring local air quality indexes and weather forecasts provides the best estimate for specific locations.
