Air Quality Update

CT DPH Air Quality Information

The air quality index is a measure of pollutants and other air quality metrics. External factors can influence air quality at any time. Therefore, it’s important to monitor air quality regularly and be prepared to take precautions if a situation changes.

If air quality worsens, closing doors and windows can help keep smoke and other pollutants out of homes and businesses. N95 and KN95 masks can help filter smoke, so consider wearing those outdoors if/when the air quality is poor.

You can find hourly updates on the air quality in our area by visiting https://www.airnow.gov/ or the Centers for Disease Control and Prevention's HeatRisk tool and typing in the zip code.

The table below describes actions to take to reduce exposure at different air quality levels.

Please note: Sensitive (at-risk) groups include people with heart or lung disease, older adults, children, pregnant people, and people who spend a lot of time outdoors.
