Rainout/condensation

[ap12]

I just started 3 days ago with a ResMed AirSense 10 AutoSet. I am getting some moisture in the mask and want to eliminate it if possible. 2 nights ago I had my tube temp at 70 degrees and moisture level at 8. In the middle of the night, I was awoken with water gurgling in the tube. For all of you that have not experienced this, it's accumulated condensation in the tube which then begins to block the airflow and it's called "rainout". I had to pull off my mask for the night.
I keep my room temp at 66 degrees, the humidity in my room is 66%, and I'm 75% mouth breather. I have now moved my ClimateLineAir tube up to 80 degrees and my Humidity level down to 5. No rainout anymore, but still have some moisture forming in the mask and it's beginning to barely drip.
Questions: 1. Should I always expect some moisture in the mask or can that be eliminated? 2. What are positives or negatives that y'all have experienced in raising the tube temp or lowering the humidity? Thanks for the help!

So, low tube temp and max humidity... not a good combination.

Thanks for the education. btw, google has over 3000 hits for rainout, just on this site.

Most people just raise the hose and let the water drain back into the tank, or out onto the floor, and go back to sleep with the mask on

If you'd filled out your equipment profile, then people could offer mask specific suggestions, like a mask wrap/liner from padacheek.com if one exists for your particular mask.

Great idea to let the condensation drain back out to the machine. I have the machine on my nightstand so the 6ft tube has to go down before it goes back up to the machine. The condensation starts to build up and can't of course work it's way back up to the machine. If I placed the machine on the floor or at the very least in a lower area than level to the bed. Thanks!

I put hose on the bed by my pillow. I have also put my machine on a library step-stool so it's lower than the bed but NOT on the floor sucking all the floor gunk into the filter.

Different masks vent better and have less issues with mask condensation. I have my Climateline set at 86 degrees, which is max. Auto for humidity. I always had condensation in my DreamWear nasal cushion (sometimes waking me at night to the point where it would wake me and I would have to shake the water out), but have no condensation in the N30i nasal cradle cushion. The N30i has many vent holes positioned along the length of the cushion, so this eliminates the condensation completely.
