I am coming from a very old Philips Respironics Series 60 CPAP machine which served me well for more than 10 years, and still works. I was offered a new AirSense 11 and was able to test it on site. This thing is noisy as *ell. When I inhale and exhale, I hear strong (white-like) noise which is extremely disturbing. They had AirSense 10 units as well, and this is what I got. The noise level is OK.
The humidifier does not do much though. Most of the water remains unused. I wake up with slight headaches. I tried Auto, then humidity level=3. Tonight, I will try the maximum level. The Philips worked just fine at level 2 or 3.
I've used a PR Remstar System One for 11 years myself and recently also got an Airsense 10. No experience with the 11.
In my case, the Airsense 10 is near silent. The System One was very quiet but the Airssense is really next level. Very happy about that because I'm very sensitive to noise. I also never had such great numbers in Oscar but that's another conversation. I've used a Dreamstation too for about 2.5 months in late 2019 early 2020 and the Airsense 10 feels even better to me than that. That machine was noisy af... Therapy was better than the System One but nowhere close to the Airsense.
As for the humidifier, they are very different beasts. My System One humidifier barely worked anymore so I had it at 3. With no heated tube, sometimes my mask remained dry, and sometimes it had a lot of condensation in it in the morning
With the Airsense, I have the heated tubing and I tried temperature and humidity at Auto and ended up with condensation in my mask. Not rainout exactly but similar to the System One. After experimenting a couple nights, last night I had temp at maximum and humidity at 5 and everything was great. We sleep with the window open even at this time so room temperature at night is probably lower than average. The other nights it barely used any water but it used at least 75% of it last night. I was also testing a new mask (new for me at least). Been on a Resmed Activa LT for over 10 years. I need to replace it as it's no longer made and, while its bulk didn't bother me before, it was starting to. So last night I used the minimalist Airfit N30 and I loved it. No condensation, plenty humidity for me and pretty quiet overall plus no leaks.
From what I understand, there's more variation than one would hope between machines of the exact same model in terms of noise. Pressure settings also make a difference. Humidity will require experimentation. Took me 4 nights to get it right for me with my new Airsense 10 and I'm sure my settings will change as weather changes (I live up in Quebec, Canada).
