you are right, CO is about the same as air. That is a myth...
We had a situation where a guy in a tent got CO poisoning but the people walking around were unaffected. I guess that supported the myth...
If CO floats then that is worse as it can float into your windows.
CO2 is harmless, you exhale it and breath it in. The mask-breathers are breathing it constantly inside their gross mask.
CO2 is harmless in "normal" concentrations. But In high concentrations can also lead to oxygen starvation and death. It is indeed rare, but can happen with inadequate ventilation when used a MIG or TIG welder running CO2 with inadequate ventilation.
