For me, both of them leak and leak a lot. Even though my insurance covers the liners, Apria doesn't have them and doesn't have a supplier for them.
I like the headgear with the Amara gel and I like that it is easy to take off the clips but the leaks wake me up a lot. I also like that you can change cushion sizes without having to get a new head gear and frame.
I don't like the headgear with the Quattro fx or the Mirage. I also don't like the clips on the Mirage. For me, where the clips are placed, they are hard to unclip, hard to get the headgear strap in them without a mirror. The headgear wears out faster than the Amara gel headgear.
This is just how it works for ME. I am sure others like both of these.
The place where I am having my sleep study titration in early December has a lot of masks and I am hoping they will be able to help me find one that works for my face! I am thinking positively on this one!
