PM2.5 pollution level: Manila better than us

S’pore does very well in global standards but Manila does even better. Having lived in Manila, and knowing that that traffic conditions there have not improved since I lived there, I’m surprised.
Neither Manila nor us meet the World Health Organisation PM2.5 recommended level of 10µg/m³. But very few cities except in Oz and NZ.
