Mask Cushion (?) Sizes/Shapes - Ross - 06-12-2015

I have 2 nasal masks (see profile). The Mirage came with my CPAP and I then got the AirFit because I thought the magnetic strap attachments might be more comfortable. Leaks with both masks have always been in the acceptable range, but after 3 nights of increasing leaks with the AirFit (10, 13 and 16L/min), I went back to the Mirage and the results were much better (1 and 4 L/min). Although I realize that various factors could account for this, I notice that shapes of the mask cushions (?) differ—the Mirage is more slender (and it certainly feels more snug).

It certainly stands to reason that there would be different sizes/shapes of nasal cushions, but is there a way to determine the size/shape of the one I prefer? Could I get one of that size/shape that would fit the AirFit? It doesn’t look like I could just switch them.

I’ve gotten a great deal of help and information from this site, and I’ve just made a donation!

Not exactly sure what you are asking. If you are asking if your face needs, say, a size 9 mask size and then you can wear a size 9 mask from any maker and it fit the same, the answer is no. Each mask is different even within the same type.

But it could be you could go a size down in the Airfit to get that snugness you like in the Mirage.

When I see an increase in leaks, I've found that washing the mask will eliminate the problem. The worst thing that can happen is this trick won't work for you.

I got an e-mail from ResMed today on "finding the right mask fit" that addressed my (apparently puzzling) question.Smile It included templates for determining proper "cushion" size. Clearly, the one I prefer is standard and the other is wide. Since switching to the standard I have minimal leaks. I assume other manufacturers have their own guides, I wonder why no sizing was done by the DME.

FWIW here's an excerpt:
Q. Where can I find mask fitting guidelines?
