Is it really difficult to understand why people don't like sleeping with a mask that makes noise?
And yes, the mask can make noise, but typically not as much as the person makes snoring for your partner. Modern ones, in particular, are fairly quiet and can be tucked under the night stand such that they make about as much noise as basic forced air venting systems do. Which is not much.
The mask can be uncomfortable some nights. They do have a variety of masks to try, though. And if it isn't working, they have other options.
That last point is actually refreshing for me in this story. So many bounce off a CPAP into nothing. Hopefully efforts like this story will help people find something that can work.
And I have a few reasons more,if you really need.
Also, some people have parters in the room where they sleep and the noise might bother them as well.
