Hadkan aktiviti luar yang berpanjangan. Kanak-kanak, warga emas, ibu mengandung dan pesakit pernafasan atau jantung dinasihatkan berada di dalam bangunan. Pelitup muka N95 membantu di luar.
US AQI (PM2.5) by city
Values are calculated from DOE’s rounded API and a 24-hour PM2.5 average. Unknown or other dominant pollutants show as unavailable. How the conversion works

Looking for weekly trends? Explore Malaysia's 7-day national average API, peak readings, cleanest and most polluted monitoring stations, and major city comparisons.
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.

Malaysia air quality and haze today: Kuala Lumpur air quality and haze
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.
