I'm still not sure if this is fake news or not.

For bronchitis you should inhale very small water salt solution.

I get it for incent or smoke but why would water do harm or my cooking smells?

It's not the water. It's the minerals in the water, which become fine airborne particulates as part of the process. Other types of humidifiers don't have this problem, though some can be prone to mold instead.
