Air quality today
The air quality in Köflach, Styria, is classified as Good. The primary pollutant identified is PM10. Three valid measurements contribute to this assessment. The PM2.5 reference value is not applicable for this report. The precise PM10 reference value recorded is 34.5752754 µg/m³.
Data is shown via OpenAQ, reflecting the latest available readings for the city. These figures represent the current state of ambient particulate matter without indicating trends or forecasts. 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 Köflach air‑quality record contains measurements for nitrogen dioxide, particulate matter ≤ 10 µm and sulphur dioxide, all reported in micrograms per cubic metre. The dataset is built from a single monitoring station, and a total of six data rows are present. Three of those rows have been refreshed within the last three days – the most recent update for each pollutant was recorded on 2026‑02‑10 at 20:00 UTC – while the remaining three rows are older, indicating that half of the available observations are not current.
For nitrogen dioxide the observed values span from about 19 µg/m³ up to 48 µg/m³, with a median of roughly 33.5 µg/m³; the 10th percentile sits near 22 µg/m³ and the 90th percentile around 45 µg/m³, showing a moderate spread around the centre. Particulate matter 10 follows a similar pattern, ranging from 34.6 µg/m³ to 54 µg/m³, a median of 44.3 µg/m³, and percentiles of 36.5 µg/m³ (10th) and 52.1 µg/m³ (90th). Sulphur dioxide displays far less variation, with values clustered between 1.99 µg/m³ and 2.0 µg/m³, a median of 1.994 µg/m³ and both the 10th and 90th percentiles essentially identical to the minimum and maximum.
These figures illustrate that Köflach’s public data set provides a complete set of three key pollutants, but the coverage is limited to one location and only half of the records are recent. Consequently, while the available numbers give a snapshot of typical concentrations and their range, they may not capture short‑term fluctuations that can occur across different parts of the city or at times beyond the older entries.
