Air quality today

The air quality in Hanau today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of approximately 29.33 µg/m³ and a PM10 level near 13.09 µg/m³, based on nine valid observations.

Data is shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Hanau air‑quality record draws on 11 measurement rows collected at two monitoring sites. All eight key pollutants tracked by the OpenAQ network are represented: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM₁, PM₂·₅ and PM₁₀), sulfur dioxide (SO₂), relative humidity and temperature (the latter is present in the raw feed but not listed among the latest values). The most recent observations for most substances were recorded on 2026‑02‑10 around 17:00–19:00 UTC, giving a snapshot that is only a few days old. Two exceptions are older: NO was last reported on 2024‑03‑11 and SO₂ on 2023‑01‑25, so those two parameters rely on data that is several years out of date.

Across the pollutants the measured values show modest variation. For PM₂·₅ the five‑day window contains readings from a low of about 7.9 µg/m³ to a high of roughly 29.3 µg/m³, with a median near 18.6 µg/m³; the interdecile spread (10th–90th percentile) runs from 10.1 to 27.2 µg/m³, indicating that most recent concentrations cluster in the middle of the range. PM₁ and relative humidity each have a single reported figure – 19.3 µg/m³ for PM₁ and 65 % for humidity – both captured at the Steinheim site on the same day as the PM₂·₅ update. The other gases are also represented by single values: NO at 2.87 µg/m³, NO₂ at 29.39 µg/m³, O₃ at 31.81 µg/m³ and PM₁₀ at 13.09 µg/m³, each measured on 2026‑02‑10.

Because the dataset contains only two stations, spatial coverage is limited; conditions can differ across neighborhoods or over short periods that are not reflected here. Moreover, the presence of older entries for NO and especially SO₂ means those pollutants are less current than the rest, so any interpretation should keep in mind that the picture is incomplete and varies by both location and time.

Data notes

The data for Hanau are based on nine valid measurements and were refreshed recently, with the latest update recorded at 2026‑02‑10T19:00:00+00:00 (updated within 3 days). This snapshot reflects conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
