About Ground-level Ozone
A harmful gas created by chemical reactions between pollutants in sunlight.
Measured in ppb
Health Impact
Air quality is considered satisfactory, and air pollution poses little or no risk.
What Is a Safe Level of Ozone?
By the EPA Air Quality Index, ground-level ozone is Good — safe for everyone up to 54 ppb (AQI 0–50). From 54 to 70 ppb is Moderate (AQI 51–100): acceptable for most people, though unusually sensitive individuals may notice symptoms. Above 70 ppb the air turns Unhealthy for Sensitive Groups and EPA health guidance applies.
Lansing is currently at AQI 28 (≈30 ppb, estimated) for Ozone — within the Good range, so Ozone levels are safe for everyone right now.
Thresholds are the official EPA AQI category breakpoints for ground-level ozone (8-hour standard). The current concentration is estimated from the measured AQI sub-index; the exact value within a band is not recoverable from the index alone.
Sources of Ozone
• Chemical reactions between NOx and VOCs in sunlight
• Vehicle emissions
• Industrial facilities
• Gasoline vapors and solvents

Today's main pollutant in Lansing is ground-level ozone (AQI 45). Important: standard HEPA filters do NOT remove ozone — only a purifier with a substantial activated-carbon bed adsorbs it. The biggest wins are cutting indoor sources (gas appliances, certain "ionizer" purifiers) and ventilating when outdoor ozone is low (early morning). A high-carbon unit helps with the gases and VOCs that linger indoors.
