## Description

AirQualityIndex.org is an independent air-quality information website that helps people explore pollution levels locally and around the world. Its global map covers 2,000 curated cities across 196 countries and provides access to 25,953 monitoring stations, allowing visitors to move from regional and country views to city and station data. Users can view reported AQI alongside pollutant measurements including PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. The site also offers practical tools such as an approximate near-me AQI lookup, an AQI calculator, city comparisons, country directories and global real-time status pages. Educational resources explain air-quality concepts, pollutant health effects and data sources, while articles and research cover topics such as seasonal smog, children’s exposure, air purifiers and wildfire smoke. AirQualityIndex.org distinguishes monitoring observations from forecast and model data, identifies sources and observation times, and acknowledges WAQI, OpenAQ and originating monitoring agencies. Visitors can save favorite locations and revisit recently checked cities. The platform aims to make air-quality information easier to find and understand.
