Vietnam Air Quality

[Watawattana]

How do you generally find the air quality in Vietnam?  Hanoi, Hot An, Ho Chi Min.

 

I see that Thailand is struggling, example is one of today's AN articles.  

 

 

I'm sure I could find the raw data online, but wondering about the general feeling on this from people who live in Vietnam.

Visually, the Hoi An / Danang area has very similar pollution to Hua Hin.  Definitely not as bad as Chiang mai, not as clear as Samui or Phuket.

 

At street level, the pollution smells much worse in Vietnam.  After walking around a city in Vietnam, my clothes smell strongly of exhaust.
