Popping moisture noise from Airsense 10

[robo2084]

I've generally had good luck with my Airsense 10. I have found I have had to up the humidity a bit (to 6 or 7) and reduce the temperature a bit (to 72 - I also like to sleep in cold temps and feel claustrophobic when the air is blowing warm).

I'm finding that after about 5 hours, moisture tends to build up in the hose, creating a popping sound as the water drops move about.

Any thoughts on solving this? Are other machines more or less prone to this problem?

you're battling physics, high humidity, low temps, condensation... maybe if you get a hose cover... or reduce the humidity.

theoretically, putting the machine lower, so there's no dips in the hose, with the hose coming out upwards from the machine, should let any water run back in... though there've been reports that doesn't always work on the air10 machines.

Thanks! Trying to move the machine lower seems like a great idea. I've noticed that when the hose is completely on the bed the problem is lessened, but it tends to fall off. Lowering the machine would create a similar effect, I think.

From experience, I have found I may get water in my hose if there is a dip in the hose. At home, I run the hose up over the headboard of the bed. When we travel, I use a hose boss to keep dips out of the hose. I also use a heated hose with a hose cover when at home. When traveling, I do not use a hose cover.

The changes you posted in your first post in this thread, are what made the problem, you broke the laws of physic's. Water will stay a vapor only if the air temp will allow it. Jim

You will have the same problem with another machine.
As previously mentioned...you are battling physics in action here and you have to find some way of keeping the air in the hose from condensing which means you have to keep it from cooling to the point it can no longer hold onto the moisture.
That involves keeping the air in the hose warmer or reducing the moisture content of the air. Those are pretty much your choices.
Having the machine lower or no dips in the hose won't prevent condensation...all it does is allow gravity to maybe help the moisture drain down into the humidifier and sometimes that works and sometimes it doesn't but I have found that just the tiny droplets of water adhering to the walls of the hose will cause a horrible racket and they don't drain so easily even if I hold the mask directly vertical.
Plus this involves the noise waking me up and I don't like anything to wake me up.

I think it's better to prevent the condensation in the first place.
A hose cozy might help enough at your preferred lower hose air temp. Or maybe just a degree or two warmer would keep that air in the hose warm enough to not release the moisture and not feel too much like hot swampy air to you.

I prefer maximum humidity delivery too...and I also prefer a cold bedroom so I know that's a recipe ripe for condensation happening.
So I have been there and done that and that's how come I know that keeping the machine or hose so that things can drain doesn't always work so great.

I have even had the moisture in my own breath condense in the nasal pillow mask and there's no where for it to go except up my nose because of the way the hose comes into the pillows...no way for it to drain unless I get in some really weird positions to get the opening to the hose aligned with the pools of water. Water can't travel uphill and that's pretty much the only way the water in the nasal pillows can go if it were to drain out through the hose unless you are standing on your head or buried face down in the bed pillow.

So it's Physics in action and you have to battle it with Physics.

It could be that you overfilled the water chamber!

Unlikely. You would just have to see how the chamber is constructed to understand why I say unlikely but it would be extremely unlikely because the chamber really can't be overfilled to the point of blowing water into the hole for the hose. It would leak horribly and run water out all over the place before you even closed the lid and with the AirSense chamber you really can't add water without opening the lid.
I have an AirCurve machine...and I can't overfill it with the lid open and to try to fill it using the air hole...way too much work.
The air hole is significantly higher than the highest water level and it's going to be pretty unlikely to have the air blowing over the water to push the water into the hold going to the hose.

Now the old S9 water chamber...real easy to overfill it and have the air push the water into the hose but not with this new AirSense/AirCurve chamber.

Thanks, I will see if I can step up the temp a little bit. I suppose that perhaps the higher humidity isn't really helping if all the moisture is condensing anyway, as well...

...or looping the hose higher. If the moisture first has to climb a hill to the top of the loop it will likely never get over the top to come down the other side. The moisture gathers at the low point in the hose path, not the high point. See https://www.cpap.com/productpage/travel ... ystem.html as an example.

Had the same problem - decided to obey the laws of physics - I adjusted the humidity level and tube temperature until I achieved settings that were comfortable without popping

I solved the isue by getting the heated hose & leaving the settings on Auto. Insurance actually paid for the hose.

OP already has a heated hose, else there wouldn't have been a setting to reduce the temperature.
