What do the AQI colours mean?

The air is clear! Pollution levels are under the recommended exposure thresholds set by the WHO for one year of pollution exposure.

Air quality is considered acceptable, though approaching the recommended WHO threshold for one year of pollution exposure.

Pollution levels are now over the recommended WHO threshold for one year. There may be certain health concerns for people with specific sensitivities.

The air is highly polluted—above twenty-four-hour exposure recommendations from the World Health Organisation. Everyone may start to feel adverse health effects, and those with sensitivities should take care when performing outdoor activities.

Levels have exceeded the recommended WHO exposure threshold for one hour. Everyone may start to experience more serious health effects at these levels, and long term exposure constitutes a real health risk.

These levels constitute emergency conditions. There can be harmful impacts on the general public, even in the case of short-term exposure.
