Air pollution causes 1 in 9 deaths, and huge parts of the world still lack access to basic air quality data.

IQAir is working to change this by empowering the world to breathe cleaner air. We operate the world's biggest real-time air quality data and community platform, comprising over 80,000 public sensors worldwide on five continents. IQAir engages citizen scientists, organizations, and governments to contribute data and fight environmental injustice by increasing the breadth and depth of air quality data where it’s most needed.
