Clueless you are not. Your question is very interesting. We often accept so many things without challenge. The question is "why do you need to humidify air when using PAP when you wouldn't otherwise? I would believe you are correct in saying the volume of air (to the lungs) is essentially the same with or without PAP. And I do accept the results; that PAP will dry out nasal passages and that a heated humidifier will remedy that. One thing that might be different with PAP (I am tossing it out for consideration) is that the static pressure in flow is higher than the atmospheric pressure (or there would be no flow). Because the PAP static pressure is higher than atmsopheric, it can hold less water vapor. Therefore it's drier than room air and the need for a humidifier with PAP. I can't think of another reason or answer to your very reasonable question.
