Hi @robbie1956, Finding the best mask for yourself is probably the biggest challenge each of us with sleep apnea faces. I've tried at least 6 different masks in the first year and now have settled on a ResMed AirFit F20 full face mask because I mostly breath through my mouth. It's best if you are able to work with a sleep medicine therapist if possible. I got my first one at the Mayo Clinic Sleep Medicine Store and then found a medical supply company closer with easier access that I liked so I was able to work with them to find something that fit my face the best and worked with the least difficulty. Even that was a struggle for the first few months. There is another discussion that you might want to check out as I think there has been discussions on different masks.

Did you have an overnight sleep test to diagnose sleep apnea? Normally when you have the test they try several styles of masks to see which one works better for you. I think they woke me up twice to change the style of CPAP mask and then told me at my follow up with the sleep medicine doctor that they thought a full face mask was the best.
