Ratings and reviews

Consider use this app if you believe in data accuracy of Thailand Air quality and noise management bureau or trust it. If not, there other apps with a lot more air quality monitoring spots, independent from government, friendly UI, much more in detail and statistics, or even including satellite images. Judging from existing apps, I rate this only 1 star.

This app is not as bad as many people here seem to think. The Thai PCD was already collecting air quality data long before people even knew what PM was, since 1996. They're the reason we have good historical data to compare against. Do note that the app provides the raw PM2.5 number in microgrammes per cubic meter. It's not the (American EPA) AQI number. Also the PCD uses vastly more accurate machinery compared to the consumer-grade particle counters in use by AirVisual et al.

This is worse than useless. It is dangerous, because of its gross inaccuracy. It reads "Very Good" air quality (PM2.5) for my location, yet at the same time numerous other weather sources (and Thai news reports) report it as "Very Unhealthy" air quality -- while I am looking out the window and am unable to see a building one kilometer away because of the thick haze.
