Question
I've been wondering now for some time if it wouldn't be possible
to clean the smog or at least reduce it in a City like L.A., using a
large version of technology like an ionizer? What am i missing
here? Thanks for your time,
Sincerely, Monte Hill

Answer
The technology and systems required would be so large as to be technologically and financially infeasible. And then it would only be after the fact: populations would be exposed to unhealthful air and their deleterious effects, and environmental damage would have occurred.

It is far far cheaper and far more effective to prevent pollution, then it is to clean up after it.
