FAQs of Thailand's Air Quality Index

(Frequently Asked Questions)


Some facts about air pollution level in Thailand and what quality of air you breathe in your region.


The real-time air quality in Thailand is 59 MODERATE AQI now. This was last updated .

The current concentration of PM2.5 in Thailand is 25 (µg/m³). The World Health Organisation (WHO) recommends 15 µg/m³ as the threshold concentration of PM2.5 for 24 hrs mean. Currently, the concentration is 1.00 times the recommended limit.

Generally, the air quality at Thailand starts deteriorating in late October. The winters are the worst-hit season in terms of air pollution.

You should wear a good N95 mask when you go outdoor in Thailand until the AQI is improving upto moderate range.

Office going people should avoid personal vehicles and use public transportations or carpooling.

(i) The primary causes of outdoor air pollution are solid, liquid particles called aerosols & gase from vehicles emissions, construction activities, factories, burning stubble & fossil fuels and wildfire, etc.

(ii) Main causes of indoor air pollution are harmful gases from cooking fuels (such as wood, crop wastes, charcoal, coal and dung), damp, mould smoke, chemicals from cleaning materials, etc.

Indoor air pollution in Thailand is as dangerous as outdoor pollution, because the air pollutants come inside the houses or buildings through doors, windows and ventilation.

In Thailand, you must use an air purifier or fresh air machine at home or office indoor and close all the doors, windows and ventilations when the outdoor air quality index (aqi) in Thailand is very high. Proper ventilation is highly recommended only when outdoor air quality is improving and moderate AQI range.
