Understanding the Malaysia API

Memahami Indeks Pencemaran Udara

The Air Pollutant Index (API), or Indeks Pencemaran Udara (IPU) in Bahasa Malaysia, is published by the Department of Environment. It follows Malaysia's own scale, which differs from the US AQI. Compare station readings and their observation times to understand conditions across the country.

About Kuala Lumpur air quality

The main number is PM2.5 US AQI calculated from Malaysia’s official Air Pollutant Index (API). We derive the 24-hour PM2.5 concentration from the rounded API and apply US thresholds. It is not an official all-pollutant AQI or a real-time NowCast.

The source API comes from the nearest DOE monitor within 75 km of the city centre. It is a station reading, not a city average. The app checks for updates every five minutes and shows the age of the observation.

The Petronas Twin Towers artwork is an illustration. The haze effect follows the API reading; it is not a camera view.
