Desperate for help. My lungs are being affected and today I am struggling to breathe from all the rainout going into my lungs.
I am constantly either coughing from the water and have dry mouth every single day. Or I get stuffy, congested nose with a headache.

What am I doing wrong? What am I missing? Is it the coldness in the bedroom? I already called Resmed and was told " I can't tell you what to set your machine at".

Facts: I'm a long time CPAP user (years). I am in Arizona where it's very dry (dry as low as 19-21% in the house). I use a Resmed Airsense 10 Auto Set and been using this for over 3 years. I use Bleep Eclipse Halos mask.

I have been using a bedroom standalone humidifier for over 3 years with no issues affecting the CPAP machine. It doesn't blow out water, only air.
Temperature in the bedroom is between 62-68 degrees. I don't turn on heat in the house and don't sleep with the windows open if bedroom humidifier is on.

Problem:Over the last 6 months, out of the blue, I am experiencing severe rainout every night. Nothing has changed with the mask, the machine, my house.

Things I have tried and didn't fix the issue:
1. Moving the machine almost to the floor on a very low table. Hanging the hose high up enough so any water would drop down into the machine.
2. Adjusting humidity, adjusting tube heat, turning off both, turning off just one.
3. I have a hose cover and I have wrapped every inch of the hose with thick towels, sleep with the hose under my covers
4. Turned off CPAP humidity and left water in
5. Turned off CPAP humidity with no water

For months, I write down on my phone what temp/humidity level I use and this rainout never leaves. I'm at my wits end. Thanks.

dry mouth

That's a sign that your lips are not closed when using CPAP. Just a few minutes of lip leak can cause a dry mouth.

Can you give a more detailed description? Does part of the hose lead down to your nose?

Turned off CPAP humidity with no water

So, you still had rainout under this condition???

Water from rainout does not get into your lungs. It wakes you up.

A gurgling cough with trouble breathing is a reason to get yourself to a doctor ASAP and I do mean ASAP!
Do you want me to name some serious medical conditions that might cause that? Or will you let a physician decide if you're healthy or not?
Machines to do not suddenly develop rainout in dry conditions.
People on the other had do suddenly develop health problems they never had.
Get thee to a doctor.
Rule out problems with your health, then start troubleshooting your machine and mask.

If you haven't already, you could get yourself a heated hose. That should take care of "rain-out".

If you still have the problem, you could try resetting the machine back to its original specs.

If you then still have the problem, you could try reducing the humidity setting a notch or two.

I'm in Arizona. Keep my bedroom aprox 68 in winter. I don't have rainout since I got rid of the heated hose. I mostly use a 1 humidity level a max of 2 if I have to have the house heater on. I hate humidity.

First, where is the rainout accumulating? In the pillows of the Bleep Eclipse Halos mask? In the short hose that connects the pillows to the main hose? In the main hose?

Second, if you are getting rainout when the humidifier is urned OFF and there is no water in it, then the moisture that is condensing in your mask or hose must be coming from your own exhalations or the ambient humidity in the air.

Now, you also write:

What is the relative humidity in the bedroom when you ARE running the bedroom standalone humidifier?

Also worth noting: condensation from your own exhalations will be worse when the bedroom is 62 degrees than when it is 68 degrees.

Finally, I'll second what ozij said:

"5. Turned off CPAP humidity with no water"

There is a condition called over active salivary glands (hypersalivation) which can cause too much saliva in your mouth. I'm wondering if this condition may be mistaken for 'rainout' from the CPAP, particularly when you have the CPAP humidity turned off and no water in the humidifier tub. The CPAP can not create water on its own. Excess saliva very well could be going down your throat as you sleep and causing a cough to clear the saliva.

Googling 'overactive salivary glands' may help describe the condition and symptoms.
