Air quality today

The air quality in Taipei is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 25.85 µg/m³ and a PM10 level of 31.0 µg/m³, based on 47 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 OpenAQ feed for Taipei contains recent measurements for ten pollutants: CO, NO₂, O₃, PM1, PM2.5, PM10, RELATIVEHUMIDITY, SO₂, TEMPERATURE and UM003. Data come from 70 rows representing 11 distinct monitoring stations across the city. The most recent timestamp in the whole set is 2026‑02‑10 23:00 UTC, and every pollutant shown has at least one reading updated within the past seven days, so the dataset is broadly fresh.

For particulate matter, the median PM2.5 value is 18 µg/m³ (range 10–25.9 µg/m³) recorded at the 萬華 site, while PM10 shows a median of 27 µg/m³ with values spanning 13 to 34 µg/m³ at the same location. The newer PM1 sensor reports a maximum of 17.44 µg/m³ and a median of about 12.19 µg/m³, both from a Taipei‑wide station, indicating finer‑particle data are available but from only two rows. Gas pollutants show narrower spreads: CO median is 0.47 ppm (range 0.2–1.22 ppm), NO₂ median 0.0225 ppm (0.0055–0.032 ppm), SO₂ median 0.0016 ppm (0.0008–0.0037 ppm) and O₃ median 0.002 ppm (0–0.0589 ppm). Relative humidity values are clustered between 48 % and 63 %, with a median of 55.6 %.

Coverage is uneven: while PM2.5, PM10, CO, NO₂, SO₂ and O₃ each have data from ten or eleven stations, PM1 and RELATIVEHUMIDITY are represented by only two rows, and temperature/UM003 are not present in the current snapshot. About 17 % of rows are classified as “old” and six rows lack a clear freshness label, so some parts of the city may rely on less recent observations. Consequently, conditions can differ across neighborhoods and times, and the available data reflect a snapshot rather than continuous monitoring everywhere in Taipei.

Data notes

The dataset for Taipei includes 47 valid measurements and is updated within 3 days, with the most recent data recorded at 2026‑02‑10T23:00:00+00:00. These values represent a single point in time and may not reflect conditions across all neighborhoods or throughout the day; air quality can vary by location and time within the city.
