Many air quality services use a single Air Quality Index (AQI), which combines pollutants like nitrogen dioxide, particulate matter, and ozone into one number. While AQI is useful as a general indicator, it has limitations:
- It reflects ambient air at a location, not what an individual actually breathes
- It does not account for time spent, activity level, or route choices
- It can vary between countries, making it harder to interpret consistently on a global scale
Instead, AirTrack focuses on personal exposure. For Premium users, we provide an AirTrack Score that gives a more meaningful, personalised view of your exposure - and helps you make practical decisions to reduce it.

Why don’t you use an AQI score?
An AQI describes the air at one place. AirTrack estimates your personal exposure instead, accounting for your route, time spent and activity level.
