Air quality today

The air quality in Brașov is currently classified as Good. The primary pollutant identified is PM10, with a measured reference value of 16.79 micrograms per cubic meter based on the latest data set.

Thirteen valid measurements were used to determine this assessment, and the information 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 dataset for Brasov contains measurements from seven monitoring rows, covering ten different pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter of 1 µm (PM1), 2.5 µm (PM2.5) and 10 µm (PM10), sulfur dioxide (SO2), relative humidity, temperature and an additional variable labelled UM003. The most recent observations were recorded on 2026‑02‑10 at 19:00 UTC for CO, NO2, O3, PM10 and SO2, meaning that half of the pollutants have data refreshed within the last week. In contrast, PM1, PM2.5, relative humidity and temperature are only available from an older snapshot dated 2025‑10‑04 at 06:00 UTC, so those parameters reflect conditions from several months ago.

Across the recent measurements, CO reached a maximum of 233.21 µg/m³ while its median value was not reported (the dataset lists –1000 as placeholder). PM10 shows a typical concentration around 16.79 µg/m³ with values ranging from about 9.18 to 532.91 µg/m³, indicating considerable variability in particulate levels. NO2’s recent median is 32.76 µg/m³ and spans roughly 17.26 to 39.82 µg/m³, whereas O3 averages 58.71 µg/m³ with a narrower spread between 34.83 and 70.49 µg/m³. SO2 remains low, peaking at 6.11 µg/m³ and centering near 4.95 µg/m³.

The coverage is uneven: three pollutants (PM1, PM2.5, relative humidity) rely on a single old record, while the other five have multiple recent entries from six to seven rows each. Consequently, the current picture of air quality in Brasov is most reliable for CO, NO2, O3, PM10 and SO2, whereas assessments involving fine particles, humidity or temperature should be treated as dated snapshots that may not reflect present‑day conditions across the city.

Data notes

The data shown for Brasov is based on 13 valid measurements and was refreshed recently, Updated within 3 days (last update: 2026‑02‑10T19:00:00+00:00). 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.
