About Fine Particulate Matter
Tiny particles less than 2.5 micrometers that can penetrate deep into lungs and bloodstream.
Measured in µg/m³
Health Impact
Air quality is considered satisfactory, and air pollution poses little or no risk.
What Is a Safe Level of PM2.5?
By the EPA Air Quality Index, fine particulate matter is Good — safe for everyone up to 9 µg/m³ (AQI 0–50). From 9 to 35.4 µg/m³ is Moderate (AQI 51–100): acceptable for most people, though unusually sensitive individuals may notice symptoms. Above 35.4 µg/m³ the air turns Unhealthy for Sensitive Groups and EPA health guidance applies.
Peoria is currently at AQI 21 (≈3.8 µg/m³, estimated) for PM2.5 — within the Good range, so PM2.5 levels are safe for everyone right now.
Thresholds are the official EPA AQI category breakpoints for fine particulate matter. The current concentration is estimated from the measured AQI sub-index; the exact value within a band is not recoverable from the index alone.
