Air quality today
The air quality in Isperih today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 value of 12.93 µg/m³ and a PM10 value of 13.26 µg/m³, based on seven valid observations.
Data are shown via OpenAQ. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
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 Isperih air‑quality feed currently provides seven recorded rows covering the full set of measured pollutants: humidity, PM1, PM10, PM2.5, PM4, pressure and temperature. All values come from a single sensor snapshot taken on 2026‑02‑10 at around 22:28 UTC (the temperature reading is logged one minute later at 22:29 UTC). Because each pollutant shows the same figure for its minimum, median and maximum – for example humidity is consistently 66.23 % and PM2.5 is exactly 12.93 µg/m³ – the dataset reflects a single observation rather than a range of measurements over time.
The data are very fresh in the sense that the most recent timestamps are less than two days old, but the coverage is limited to one reporting moment per pollutant. This means there is no information on how values fluctuate throughout the day or across different locations within Isperih; conditions can therefore differ by place and time even though the current snapshot shows a uniform set of readings. The pressure reading stands at 979.03 hPa, temperature at a chilly 3.47 °C, while particulate matter concentrations are modest – PM1 at 12.44 µg/m³, PM4 at 13.24 µg/m³ and PM10 at 13.26 µg/m³.
In summary, the dataset offers a complete but singular view of seven key atmospheric variables for Isperih, all recorded within the last two days. The lack of multiple rows or older entries means there is no historical spread to assess variability, so any interpretation should consider that actual air quality may vary across the city and over time despite the recent snapshot.

Data notes
The data shown for Isperih reflects seven valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑10T22:29:00+00:00. These values provide a recent snapshot of ambient conditions but represent only limited sampling points; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this overview.
