What this means
The Air Quality Index (AQI) is a 0–500 scale set by the EPA. 0–50 is Good (everyone is safe outdoors), 51–100 is Moderate (sensitive groups should consider limits), 101–150 is Unhealthy for Sensitive Groups (kids, seniors, asthma), 151+ is Unhealthy for everyone. Utah AQI is usually Good or Moderate, but spikes during wildfire-smoke events and summer ozone days.
What you can do
- AQI > 100: limit prolonged outdoor exertion if you have asthma, COPD, or heart disease.
- AQI > 150: keep windows closed, run AC, avoid outdoor exercise.
- AQI > 200: stay indoors, use an HVAC filter rated MERV 13+ or a HEPA purifier.
