What is Ozone Pollution?

Bad or ground-level ozone pollution is created when vehicle and other emissions mix with pollutants and are heated by the sun. Warmer weather increases ground-level ozone pollution.

 

What Makes Air Quality Unhealthy?

The Air Quality Index (AQI) grades air quality based on ground-level ozone, particle pollution, carbon monoxide, sulfur dioxide or nitrogen dioxide levels. Visit airnow.gov or watch local alerts.

 

Protect Your Lungs from Ozone Pollution

  • Watch local air quality advisories.
  • Stay indoors as much as possible and when ozone/pollution levels are high.
  • Keep windows closed.
  • Take medications exactly as prescribed.
  • Use the circulate setting on your home thermostat to keep polluted air out.
  • Exercise or be outside in the morning when ozone levels are lowest.
  • Call your doctor if symptoms increase or if you need more medication.
 
Facemasks are highly encouraged to limit COVID-19 infection, but provide no protection against ozone.
