Read the number. Understand the moment.
Air changes with weather, location, and time. A reading is a starting point, not the whole story.
01
Look at the place
Check that the observation applies to your reporting area.
02
Look at the time
Notice whether the information is current, a forecast, or a past observation.
03
Look after one another
Use official guidance and consider the needs of people who may be more sensitive.
A GENTLE REMINDER
A green day is not a promise of risk-free air
AQI covers specified outdoor pollutants, not every possible exposure. Conditions can vary across neighborhoods and indoors.
