Computed on the US EPA AQI scale from PM2.5 and PM10 concentrations; the city AQI is the higher sub-index (the dominant pollutant). Bars show the sub-index out of 500.

What this air does to your body

0.9
cigarettes/day equivalent
Breathing today's PM2.5 (19 µg/m³) is roughly like smoking 0.9 cigarettes a day — Berkeley Earth's rule of thumb (22 µg/m³ ≈ 1 cigarette).
−1.4 yr
life-expectancy impact
If this level held all year, it would cut average life expectancy by about 1.4 years versus the WHO guideline (5 µg/m³), per the AQLI method.

About air quality in Taipei

This page tracks the Taipei Air Quality Index using measurements from public monitoring stations aggregated by OpenAQ, reported on the US EPA AQI scale — the international standard used by most worldwide air-quality services. The index runs from 0 to 500; the higher the number, the more polluted the air and the greater the health concern. It is calculated here from fine particulate matter (PM2.5) and coarse particulate matter (PM10), the pollutants that most often drive urban air quality.

Air quality in Taipei varies through the day and across seasons with traffic, industry, weather and — in many regions — seasonal biomass or crop burning. Checking the live reading before outdoor exercise or a commute helps you decide whether to adjust timing, wear a mask, or keep windows closed. We only display a number when a recent station reading exists; if you see "data updating", we are waiting on fresh data rather than showing an estimate.
