ResMed AirFit N20 Nasal CPAP Mask
[63501, 63502, 63503, 63535]

It is very easy to use, and the fit is great, but unfortunately, it is not the correct mask for me. Because the Airsense 11 was new to me, and my old mask did not work well with it, I purchased this one, hoping it would be the right one. I have since determined that I probably need the full mask type.
