Mask type for airfit n20 in dreamstation

Not sure what to use, x1, x2?

It probably does not matter.
Respironics "probably" invented this confusing system to discourage the use of competitor's masks.
ResMed's mask settings go by type of mask, allowing for use of any similar mask.
Look up the setting on a similar Respironics mask, and use that. --the setting, not the mask--that would be silly.

Actually Phillips Resp. recommends the setting be 0 for all masks not made by them.

Interesting. What would difference be? I left it at x1 and sleep data was similar to previous resp mask. I'll put at zero and see.

You skip over that setting. It doesn't apply for masks not listed on the package. I know this because I actually called my DME on this subject.
