Don't think this would be true in any city in Asia or for city centers around the world.

- clairity 6y agoi live in LA on a relatively busy neighborhood street and according to my air quality meter, it’s true. concentrations go down during the day (windows open) and up at night (windows closed). edit: i mentioned the road to note that outdoor pollution is higher during the day, yet opening the windows despite that lowers overall particulate levels indoors. it may be different in indian cities or cities like beijing with much higher pollution levels.
