How to read these numbers
The air quality index tracks pollution: ozone, fine particles (PM2.5), dust, and exhaust. Good and Moderate days are fine for almost everyone. At Unhealthy for Sensitive Groups, people with asthma or a heart condition feel it first. Unhealthy and above means everyone should cut back time outside.
Pollen is not part of this score. A Good air day in Idaho can still be a rough allergy day, so check Idaho pollen levels too before you plan a long day outside.
