I am 80 years old and have been using a lung nebulizer four times a day for several years. Why? Because as a stupid young person, I smoked tobacco!
I now have COPD. Why do I want cleaner air? Because, I can't breathe the outside air when there is smog! I have to stay in my home on smoggy days. If I have to go out, I need to wear a nose mask!
One piece of advice for young people, don't smoke!
