This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Canton, Ohio is classified as Good today. The primary pollutant measured is PM2.5 (fine particles). Recent observations show a PM2.5 concentration of approximately 4.43 µg/m³ and a PM10 level near 46 µg/m³, based on eight valid measurements collected through OpenAQ.
These values indicate that the ambient air meets the criteria for the Good category under the current assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The Canton air‑quality record draws from four monitoring rows, but the data are uneven across pollutants. Carbon monoxide (CO) appears in a single row dated 2019‑08‑22 13:00 UTC, showing a constant value of 0.3 ppm at the Canton site. Fine particulate matter (PM2.5) is reported from two recent rows, both updated on 2026‑02‑11 00:00 UTC at the Canton Fire St8 location; values range from a low of 32.2 µg/m³ to a high of 37.4 µg/m³ with a median of 34.8 µg/m³, and the 10th–90th percentile band spans roughly 32.7‑36.9 µg/m³. Coarse particulate matter (PM10) is captured in one row, also refreshed on 2026‑02‑11 00:00 UTC at Canton Fire St8, reporting a single measurement of 46.0 µg/m³.
Overall, the freshest observations are from early February 2026 for PM2.5 and PM10, while CO data are more than six years old, indicating limited recent coverage for that gas. The station count shows two rows providing PM2.5 values versus one each for CO and PM10, highlighting a modest bias toward fine particles in the current dataset. Because most rows are recent except the lone CO entry, the snapshot offers a clear picture of particulate conditions on 2026‑02‑11 but provides little insight into current carbon monoxide levels.
In practice, Canton’s available data give a narrow temporal window: PM2.5 values sit within a roughly five‑microgram range and cluster around the mid‑30s µg/m³, while PM10 is recorded at a single 46.0 µg/m³ point. The scarcity of rows—four in total—and the age of the CO measurement mean that air‑quality conditions can still differ across neighborhoods and times not captured here.
