I brought my AQI monitor to Saigon. I was curious to see the air quality. Saigon’s air is getting worse but I would argue it has always been bad. I still remember my black feet when moving to a villa in Thu Duc back in 2004.
Anyway, here is a reading I got from the room I am staying in. Not bad. With the air conditioner on, it drops below 50 which is healthy.
I did a calibration test by comparing this reader with the US Consulate reading here in Saigon. My AQI gave me a reading of 84 PM2.5 while the US Consulate gave a reading of 78. I was about 1 km away.
I will do a more thorough review later.
