I found this on ResMed's site under FAQs
The red was added by me for emphasis only.
It does refer to the humidified air as being "warmed" - but does NOT specify a temperature.
Water in my Hose
I can't use my humidifier during some nights because my hose fills up with water condensation. What can I do about this and why does this happen?
This condensation is called "rainout."
If your room is cold, the warmed humidified air hits the colder room temperature and cools. When air cools, the amount of humidity (water vapor) that it can hold is reduced, which causes the humidity to "rain out."
The amount of water air can carry varies with temperature: warmer air can carry more water while cold air can carry less. As warm air becomes cooler (eg, overnight), it has less capacity to carry water, so water condenses and forms droplets.
Also, page 29 of the 2011 Clinical Guide for the S9 states (under H5i Technical Specifications) that the "Maximum gas temperature at mask is less than or equal to 106 degrees F (41 degrees C)". Not quite sure how to interpret that !
My H5i settings for the Summer are Auto (80% Humidity) with ONLY the temperature changed to 72 degrees F.
During the winter, I will return to full Auto (80% Humidity with the default temperature of 80 degrees F.
I definitely feel warm air at the mask even on the Summer setting. With the Winter setting, that air at the mask is felt even more. Just how warm is not known to me.
