This is the mask my doctor's office decided was the best fit for my face. I have to agree that it did work best out of the masks in their selection. But I found a much better mask (Philips Amara) here on Cpap. com.
I have a big nose, which is a problem for most full face masks. This mask actually was pretty good at keeping a seal, though I'd regularly get leakage along the sides of my nostrils that would shoot air directly into my eyes. The big issue with the Evora, though, is the low quality white tube that connects the mask to the main tubing. From the moment it came out of the package, that tube would leak air from the joint where the flexible tube meets the hard nozzle that inserts into the ClimateLine tubing. It was the same issue on multiple tubes, so not a single defective tub. I had to wrap the tube in electrical tape to reduce the leakage so my CPAP usage reports would actually show a halfway decent seal.
