Air Quality

​Air Quality Report - June 2023

Connecticut Department of Public Health (CT DPH) Air Quality Advisory

The air quality in the Northeast region of the United States has been affected by the ongoing wildfires in Canada. Connecticut, in particular, has experienced significant fluctuations in the Air Quality Index (AQI) due to these wildfires.

Expect daily variations in air quality levels, which can change based on shifts in wind patterns and efforts to control or extinguish the Canadian wildfires. It is crucial to monitor air quality regularly and be prepared to take necessary precautions as the situation evolves.

In the event of deteriorating air quality, it is advisable to keep doors and windows closed to prevent smoke from entering homes and businesses. When the air quality is poor, wearing N95 and KN95 masks outdoors can assist in filtering smoke.
