I too sleep with my Mutt. He is lovely, but does not like me wrapping the hose over him. I have had a few squeaks and whistles too, but I think they were coming from him....LOL

Thanks for the reply and I guess it was dust in the exhalation port. Mine (maybe everyones?) had tiny little holes in it almost like a screen. I finally just took the mask and BLEW really hard in those little holes and the noise stopped. 2 of my 3 dogs sleep in bed w/ me so between normal dust, dog hair and dog dander, no bit surprise if a bit of microscopic fluff got in there. I'm about 6 weeks into my CPAP and though I don't LOVE my mask I do love the better sleep quality I am getting.

I didn't realize that I really avoided and almost dreaded going to sleep even though I was dead beat tired. And every single morning when I got out of bed, all I wanted to do was go back to sleep, because by the wee hours of the AM I was sleeping like a dead person out of sheer exhaustion. Now I wake up when my alarm goes off and sometimes I even TRY to go back to sleep. NOPE not happening. I think because I've actually had sufficient quality sleep. What a novel concept. That being said... off to bed!!

I answered this, but apparently it did not post.

Whistling can be due to air leaks, dust in the exhalation port. etc.

Did you resolve the issue yet?

Thanks again. I guess I have the humidity so low that it hardly uses much water at all. I'm now filling it to half full instead of max. I still have water left in the AM.

As for the whistling, I'm not sure that we're talking about the same thing, but my mask sometimes makes this faint whistle. And it's not a leak. But on my make there is an air outlet (for want of a better term) that has air coming out it. After I do a weekly thorough cleaning of my mask, I blow into those teeny tiny holes and i haven't had any more whistling. You'd have to actually have the mask on to hear what I hear, but it drives me NUTS!!!!! I'm like the princess and the pea.... the least little thing can keep me awake.

My DME also said I could put in whatever I discovered I needed. She also told me that if it ran out of water while I was sleeping that it wouldn't harm the machine at all.

I use a ResMed S9 Series Apap.

Yes, it works fine only partly filled. During really dry weather when I crank my humidity up, I can go through all/most the water in a night. I am assuming that it still works properly when it is running on the last of the water. It is a pretty simple device. Just a warming plate and water to make steam. The only problem would be if you ran out of water half way through the night and was cooking that aluminum plate with no water to protect it.

Be sure to ask your DME this question the next time, but in the meantime just use a little more water than you think you will need. Best of luck.

Im hardly an expert as i have only had mine for about a week or so but the tech suggested to me that I could watch how much the machine uses and put less in once I was sure what it needed. Hopefully someone else will answer too

I use a Respironics Remstar with a humidifier. The DME rep and the instructions say to fill the humidifier reservoir to the Maximum line. But I don't like a lot of humidification (usually set at 1 or 2 as Texas summers are HUMID). So when I wake up in the morning I have 3/4 of the water still in there. I know it's not ultra expensive but why waste it? Does anyone know if it functions just as well only being filled to 75% or even 50% capacity? The reps. therapist at the DME provider is on vacation til next week so I could always fill it to 100% until she's available. There is an emergency tech on call but this is hardly an emergency.

Thanks for your advice.
