iqair has pretty sparse coverage, especially in developing areas. A lot of places with really shitty air do not hit the top simply cause the service is effectively blind in those places.

However, I regularly see a lot of Balkan cities hitting the top 10. Sarajevo was #1 quite a few times. Not sure whether it's really worse than Delhi or Beijing, but sometimes it's really really bad. Like, if you imagine the most smoky bar you ever visited, where you see nothing but the cigarette smoke and can't breath. That's how you feel on the street.
