The Illinois Environmental Protection Agency has determined that the
"Air Pollution Action Day" designation will remain in effect for the
greater Chicago Metropolitan Area through midnight CDT tonight.
A Chicago area "Air Pollution Action Day" is declared when weather
conditions are such that widespread ozone and or particulate levels
are expected to be at or above the Unhealthy for Sensitive Groups
(USG) category of the Air Quality Index (AQI) for multiple days.
Ozone is expected to be the primary pollutant of concern although
smoke/PM2.5 may also become a concern later in the work week.
Active children and adults, especially people with pulmonary or
respiratory disease such as asthma, should limit prolonged outdoor
activity.
Area residents are urged to reduce pollution levels. Air quality
forecasts, current air quality, and tips on how you can reduce your

...Air Quality Alert in Effect Through Saturday, July 18, 2026...
The Michigan Department of Environment, Great Lakes, and Energy
(EGLE) has issued an Air Quality Alert for Friday July 17 and
Saturday July 18, for elevated levels of fine particulate due to
wildfire smoke. Concentrations on Friday will range from Very
Unhealthy in southern areas to Hazardous in the north. On Saturday
concentrations will range from Unhealthy for Sensitive Groups (USG)
in the south to Very Unhealthy in northern portions of the state.
This is a Statewide Air Quality Alert.
Plumes of smoke from Canadian wildfires continue to drift across the
region. Elevated fine particulate due to the smoke will continue
through Saturday. The threat of increased ozone may come into play
Saturday as well.
It is recommended that, when possible, you avoid strenuous outdoor
activities, especially those with heart disease and respiratory
diseases like asthma. Monitor for symptoms such as wheezing,
coughing, chest tightness, dizziness, or burning in nose, throat, and
eyes.
Everyone should seek cleaner air indoors and keep activity low.
While indoors, take action to improve the indoor air quality such as:
- Closing windows and minimize opening of doors.
- If HVAC systems are not equipped with MERV-13 filters or higher,use
portable air cleaners.
- Avoid activities that make indoor air quality worse:
burningcandles, using vacuums without a HEPA filter, using gas
stoves more than necessary, smoking, spraying aerosol products.
If you must be outdoors for short periods of time:
- Wear an N95 or P100 respirator marked with "NIOSH." The
respiratorshould fit tightly, collapse as you breathe in and not
let air in from the sides.
- Do not use masks for children under age of 2.
