Almaty also has terrible air quality, but looking both at averages and extremes, it's about 3-4 times cleaner than this place.
As I said, it currently looks okay due to some wind, but it's a short abnormality and the first relatively clean "window" for the past ten days. Look at this station's history and you'll see conditions more typical for this region.
Even historical data shows "only" 310 µg/m³ of PM2.5, but this is also misleading. The new network includes 26 more accurate stations spread all over the city, but the public portal for these data is being worked on. Hopefully next time this subject comes up on HN I'll have something to link to.
Several of the nearby stations are simply not working and always show zero.
All I'm trying to say is that using IQAir data to rank anything global is exceedingly misleaing.

No. I would have mentioned Almaty as it's big enough so that at least some people would have heard about it. I'm in this dump:
