I have a size small N20. The DME lady fit that one. I am smaller than a the smallest measurement for the N20. I have a narrow face so I think the small is correct. That's the one that was fine sitting up at the DME but painful lying down.Pugsy wrote: ↑Sun Sep 26, 2021 7:27 pmThe most common error made by anyone with any type of mask is they crank things down way too tight.
Generally speaking if a mask is causing pain in the teeth area....it's way too tight. Should never cause any sort of tooth pain unless bad teeth are already present.
If any mask causes pain of any sort it is either fitted improperly or the wrong size.
I was fit for an F20 at the sleep lab. I thought it was odd that I was given a medium for the F20. How can that be possible? That's the one that pushes my cheeks into between my teeth.
I am wondering if it would help get used to any mask by wearing it around the house really loose. Or would that be counterproductive? I'm wearing the N20 very loosely right now as I type. It doesn't really bother me, but I see I'm getting dents and red marks on the bridge of my nose.
I asked the lab lady about an airtouch to avoid red marks. She said that's not what they are for. She claimed they are for people with folds and bumps in their skin to settle into the folds. She said that's not me.
