Live with my family in Haarlem. Born in Manchester, UK.

I've found this https://www.cpap.com/productpage/resmed-climatelineair-oxy-tube-airsense-aircurve-10 And on another site was written that Climate Line Max for an S9 is not suitable for Airscense 10.
I've never heard about that and my husband has never told me such things. Maybe your mask is very tight and switching on another one would be a good decision...
