Melting Non-Heating Hose on Resmed Airsense 10

One of the core reasons for upgrading to the Resmed 10 was because my old Resmed S8 didn't have a humidifier. Since I don't need (or want) a heated hose, I use my old S8 hose, as the slimline that comes with the Airsense 10 doesn't deliver enough pressure for me.

I've read that the 10 recognizes whether or not a heated hose is attached, so I'm baffled as to why the machine is melting/softening the rubber end of my hose. I like my humidifier level set to 3 or 4 (out of 10). The machine knows I don't have a heater hose attached (or else it would have offered separate humidity/hose temp options, which it doesn't), yet it still attempts to heat the hose. This melts/softens the end of the hose so that after a few months it no longer attaches firmly to the machine.

So there seems to be no way to use a standard hose with the humidifier...? I have to purchase a (heavier) heated hose and set the hose temperature to off? That makes no sense.

The machine should only be able to heat a hose that's heated by way of electrical contacts at the connection point. The non heated hose shouldn't be getting hot or melting unless you have a short in the connector next to where the non heated hose attaches. I would look very closely at the attachment point on your machine and make sure it's not damaged. With out having something that's electrically conductive there should be no way for your machine to warm or heat a normal hose, even just the end.

Good luck finding out what's wrong with your machine. Let us know what you ultimately find out.

And make sure your home wiring - at least to that room - is in good shape. Even a little glitch can keep an outlet/plug at a slightly higher heat itself that minimally powers - all the time - whatever is plugged into it without your realizing it.

When the rubber end of the hose "melts", it is rarely due to heat.
More likely, it has been exposed to a solvent.
What did you clean it with?
I discovered some time ago that using vetwrap is a very bad idea for that exact reason.
The adhesive makes a sticky, gooey mess over time, and totally yucks up the hose ends.
Vetwrap is only for TEMPORARY use---who knew?
Edit: don't use the old hose--it is deteriorating, due to AGE.
The Airsense machines have a setting for regular or slimline hose.
Use the correct setting for whatever hose you use.

what you suggest is simply not happening, because the "heated hose" is heated by a heater element *IN THE HOSE*, not by the cpap machine itself doing anything (other than supplying electricity to the self heating hose.

buy better hoses.

eh, not applicable.

if the machine is set properly, the slimline hose delivers the same pressure, and flow, as the regular hose, but, only if the hose setting is correct on the machine.

This sounds like a machine malfunction of a chemical exposure (as somebody also suggested).

Another possibility is that this hose is just too old and needs to be replaced. Perhaps the "melting" that you describe is the plastic breaking down.

Thanks, all, for the responses. I've never cleaned the hose with anything other than "clean" soap and water -- same as my masks -- so it wouldn't be a "chemical" issue. I'm still not convinced that it's not a heat issue, but I'll accept that perhaps the hose is just old and subject to self-deterioration. The problem just never showed itself until a few months after I got the Resmed 10. I'll try a new plain hose and cross my fingers.

Thanks!

given that the only "heat" in a resmes airsense 10 is the plate on the bottom of the humidifier that warms the water....
