If I live in a polluted city, is there any facial mask that is proven to filter some—most?—of the pollution?

Let's say that moving out is not an option :)

The best thing you can do is to get a good quality indoor air filter for your home, office and if you have one, personal vehicle. And change the filters as appropriate.
