I have a full beard and 'stache --I've spent HOURS with the RT trying on different masks at different pressures. Here is what I have learned:
1) Facial hair has the potential to make any mask leak, expecially if you roll/move around in your sleep. Because the hair is keeping the silicone away from your skin, you will simply not get as secure of a seal as you will without facial hair. Having said this, the best seal that I obtained, without having to crank the straps tight, was with an
Activa. I believe the
Activa really is a tremendous mask but, it still leaks somewhat no matter how long, or short, my beard is. Also, the
Activa, like every other nasal mask I've tried, chews a nasty groove into the bridge of my nose. Even with the straps really loose and the
Activa cushion nicely inflated, I still get a bleeding, chewed-up nose bridge.
2) A
nasal pillow system (Breeze,
Swift, Aura, Comfort-Lite) has no seal problem related to facial hair.
I found the
Breeze gave a great seal and was really stable when I rolled around, but I did not like it pushing against my upper lip and I did not like the hard piece at the back of my head.
The
Swift is comfortable, seals well and stays fairly stable, but makes a bit of a "woosh" noise upon inhalation -I got used to it and use the Swift most nights.
I have been using the
Respironics Comfort-Lite Pillows for about 4 months and find it remarkably stable and comfortable as long as your pressure is not above 14. Some others on this site love to bash this interface, but I find it to be very quiet, comfortable, easily adjusted, and easy to sleep with. I roll around like crazy and this sucker stays in place.
I'm waiting for my Aura to arrive, so I don't have an opinion on it, yet.
Overall, if you have facial hair, try out the
nasal pillow systems, train yourself to not mouth breath and use lots of heated humidity. I found that a few months of Flonase (to reduce inflamation in the nasal/sinus system) use of the pollen filter in the XPAP machine, and a chinstrap (and occassional tape/ACE bandgage) helped me to stop mouth-breathing. Also, having an AutoPAP makes a HUGE difference as, overall, your pressures will be lower.
Good-luck and keep with it!
