Read the AQI colors
The particle-pollution AQI describes outdoor health concern. It is not an indoor air measurement or a percentage of smoke.
Follow the health guidance attached to the reading on AirNow. About the AQI
Smoke overhead isn’t the whole story.
A plume can be high above the ground. Clouds and darkness can limit satellite observations. Particle pollution can also come from sources other than wildfire.
Your indoor air can be different.
Outdoor AQI cannot tell you whether your room is adequately filtered. Use the map for context, follow local alerts, and use your clean-air plan to improve your setup.
