8 Month old Resmed Airsense 10 making a whirring noise

[JonMichael85]

Hey guys,

First I wanted to say hey as this is my first post, even though I've lurked for awhile.

So my Resmed Airsense 10 has started making this odd whirring noise whenever I breathe. It doesn't do it in the beginning of the night, I woke up about an hour and a half into sleep last night and noticed that it was starting up but was still kind of faint. By the time it was time for me to get up, it was pretty loud.

The whirring stays constant until I breathe, and it raises to match my breath. It's been doing it for three nights now, and I changed my filter and mask two days ago, and the noise continued. Someone had suggested to me that it was my reservoir, and while that's possible it seems like it's clicked in tight and the noise doesn't seem to be come from the tank. The noise seems to be coming from around the area where the air comes in through the filter and into the CPAP, not directly at the filter but a little bit deeper into it. It's been keep me up at night and is extremely frustrating. I plan on taking it by my supply shop to see if they can look at it on Monday.

My questions are:

1. Has anyone else experienced this noise and what the heck is it?

2. Is this a simple fix and something I could fix myself?

3. If there is an issue with my machine, is it safe for me to be wearing my mask? As in, I'm not breathing in and burning plastic or anything like that?

4. If it's something that is either replaced or repaired, in your experience, how does that work? I'm sure it differs from company to company, but I'm (probably unjustifiably at least in the short term) terrified of sleeping without my CPAP for any amount of time

Thanks in advance!

Quite a long time since you posted this and no reply. Did you get the problem solved? My 4 month old unit started doing the same last night.

I, too, have the same issue. I spent a significant portion of time bouncing in and out of bed last night to try to stop the insane noise coming from the hole directly behind the filter. I will carefully disassemble the thing tonight to see if there's something in there. I had changed the filter, changed water reservoirs, clicked in properly, not overfilled...still no luck fixing it. Slept sans the machine last night as a result. It drives me absolutely batty!

In three years, only three people . . .
Out of thousands sold.
Since the OP never came back, the problem must have been solved or just vanished..
The other two of you can go back to your dealer, reproduce the phenomenon, and let them deal with it.
Or it went away already--such a bummer!
