Air Quality Alert: Philadelphia Residents Face Unhealthy Levels for Sensitive Groups

Current Air Quality

In Philadelphia, PA, the air quality index (AQI) reached a peak of 119 on March 15, 2026. The primary pollutant of concern is fine particulate matter (PM2.5), which is currently in the “Unhealthy for Sensitive Groups” category. Other measured pollutants include Ozone (O3) with an AQI of 40 (Good) and PM10 with an AQI of 26 (Good).

What This Means

An AQI level of 119 is classified by the EPA as “Unhealthy for Sensitive Groups.” This means that while the general public is not likely to be affected, members of sensitive groups may experience health effects from the air quality conditions.

Who Should Take Precautions

Groups at risk include people with heart or lung disease, older adults, children, and teenagers. These individuals are more likely to be affected by the presence of fine particulate matter in the air and should monitor their symptoms closely.

What You Should Do

Sensitive groups should reduce prolonged or heavy exertion outdoors. It is recommended to take more breaks and engage in less intense activities. Watch for symptoms such as coughing or shortness of breath. The general public is less likely to be affected and can continue normal outdoor activities.
