Air quality today
The air quality in Haarle today is classified as Good. The primary pollutant measured is PM10, which refers to coarser particulate matter.
Four valid measurements were recorded, and the reported PM10 reference value is 19.79 micrograms per cubic metre. 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 data set for Haarle includes four measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or smaller (PM10). All values are reported in micrograms per cubic metre (µg/m³). The city’s air‑quality profile is built from a single monitoring location, Hellendoorn‑Luttenbergerweg, which supplies one row of data for each pollutant. Because there is only one station contributing to the record, the statistical summary for every compound shows identical minimum, median and maximum values, indicating no observed spread across multiple sites.
The most recent readings were all captured on 2026-02-10 at 21:00 UTC, which places them well within the “updated within 7 days” freshness window. This means that, as of today (2026‑02‑14), the available numbers reflect conditions measured only a few days ago and are therefore relatively current for Haarle. However, the limited spatial coverage – just one sensor – means the figures represent conditions at Hellendoorn‑Luttenbergerweg rather than the whole city, and variations elsewhere may not be reflected.
Specifically, the recorded concentrations are 0.11 µg/m³ for NO, 20.93 µg/m³ for NO₂, 16.56 µg/m³ for O₃ and 19.79 µg/m³ for PM10. Because each pollutant’s dataset consists of a single value, there is no range to describe variability over time or across locations within Haarle. Users should keep in mind that air‑quality can differ by neighbourhood and moment, and the present data provide only a snapshot from one point in the city.

Data notes
The data shown reflects four valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10 21:00 UTC. This snapshot provides a brief overview of current conditions; however, air quality can differ across neighbourhoods and change throughout the day, so values may not represent every location or moment in Haarle.
