Can you depend on the mask fit feature on a Resmed cpap? Struggling with micro and Swift Lt t he better ones of my bunch. I use the remstar auto c flex.

Are you referring to the online measurement guide? It can be helpful (for any mask fitting), but I wouldn't go solely with it as it told me some time ago that a mask I already had and liked wouldn't be good for me, and recommended the wrong size in another one. You need to either just get the DME to let you try on (in-house) as many masks in diff. sizes as possible, hopefully while lying down with a pillow, or spring for the return insurance Cpap.com provides to let you try different ones. It helps, of course, to go through all the masks on their site and look hard at different features, but even then it can be misleading as we all have different faces and sleep differently.

No, the mask fit feature on the resmed elite11 auto epr.

It depends on your pressure. The Mask Fit feature's pressure is 10cmH2O.
