Enter the API reading for your area to see its category and what to do. Get today's reading from the Department of Environment, because it changes by the hour.

Live air quality
This is a satellite and model estimate for the chosen city, not a station reading. It can differ from the DOE's official API. The AQI is worked out from the latest hour's PM2.5, not a 24-hour average.
Nothing is calculated from your input except the category. The DOE converts pollutant levels into the API; this page reads the number you enter.
API

0–50
Good
51–100

201–300

301 and above
Hazardous
Today’s live readings: the Department of Environment publishes hourly API by station on its API portal. Use the station nearest you, then enter the number above.
An API reading of 135 is in the 101–200 range, so the category is Unhealthy. Cut back on long or heavy outdoor activity, and wear a well-fitting N95-type mask if you must be outside.
Why your number may differ
The API changes through the day and differs between stations, so use the station nearest you. The advice here is general, not medical. People with asthma, heart disease or other conditions, pregnant women, children and older people should follow their doctor’s advice. School and workplace closures follow official announcements, not this page.
Frequently asked questions
What do the API ranges mean?
Malaysia reports 0–50 as Good, 51–100 as Moderate, 101–200 as Unhealthy, 201–300 as Very Unhealthy and above 300 as Hazardous. The DOE works out a sub-index for each of the five pollutants in the API system and reports the highest one as the API.
Where do I get today's API reading?
From the Department of Environment, which publishes hourly readings by station. Use the station closest to you, because readings can differ a lot between areas.
Do ordinary masks protect against haze?
Cloth and surgical masks catch little of the fine particles in haze. A well-fitting N95, KN95 or FFP2 respirator filters much more. Children and people with breathing problems should ask a doctor.
