DoE clarifies discrepancy between API readings and third-party air quality indices
The Department of Environment has explained why air quality measurements displayed on independent applications often differ significantly from official API readings. The variance stems from variations in measurement methodology and data sources used by different monitoring systems.

KUALA LUMPUR — The Department of Environment (DoE) has issued a clarification addressing public confusion over discrepancies between official Air Pollutant Index (API) readings and figures reported by third-party air quality monitoring applications.
The DoE attributed the differences to methodological variations between monitoring systems. While the official API utilizes data from a specific network of monitoring stations operated by the government, independent air quality applications may employ alternative measurement techniques, different sensor locations, or interpolated data to generate their readings. These technical distinctions can result in notably different air quality assessments for the same geographic area.
The department emphasized that the official API remains the authoritative measure of air quality in Malaysia and is the standard used for issuing health advisories and triggering air quality management protocols. Members of the public are advised to refer to official DoE channels and the Malaysian Air Quality Index portal for accurate, government-verified air quality information.
The clarification comes as air quality concerns continue to affect the region during certain seasons, prompting increased public monitoring of pollution levels through various digital platforms.
