It always made a noise as I breathed while using it, but the last day or two, my nose piece would fall off when I took my mask off to get up in the morning or go to the bathroom.
I would snap it back on and it still fell back off a couple of times, so the last time I really push on it, but was scared I might break in mask.
Well this time I guess it was snapped back on really good because I was very surprised that the mask became very silent
So silent that I didn't think it was working and had to put my hand up to the elbow to feel for air. Never having a CPAP before I had no idea how silent they are supposed to be.
Never felt any air escaping though.
