"I am a longtime user of the Resmed Quattro mask, as the "least worst" option in terms of fit - I still fight with leaks constantly due to the round shape and asymmetry of my face.

My doc recommended trying a chin strap. The ones available seemed like a pain to use with a full-face mask (mostly due to interference with the mask on the chin). However I saw the HR has the flap under the chin, so I thought I'd give it a try.

It was promising - the chin flap does indeed keep my jaw from dropping and makes a much more stable mask than the Quattro when I turn on my side. However the fit still doesn't work out in the areas under my cheekbones. In order to stop the leaks at all I need to make it quite tight, and the pressure on my cheekbones is then too high to be comfortable.

Pros: Chin flap, pliability of the whole mask gives some chance of a decent fit. Inner flaps help the seal a lot. Less obstruction of vision, if I had a TV I'd be able to watch it with this on. :-) Seems well-made. Easy to clean, reasonably easy to put on and take off. Hose quick-disconnect is also nice.

Cons: Doesn't fit well on my round face. Needed to be cleaned before first use; the mask had some sort of powder on it even though it was sealed in its bag (I presume it's a release agent from the molding process, it seemed harmless). Very loud exhaust, and vents straight at my spouse.

I intend to give it another try when I can afford a couple bad nights of sleep. Again it does seem promising, but for now I'm back to my Quattro."

"This mask is comfortable and the plastic is very soft and pliable. I just had my first successful night with it after the first three nights of trials. The key with this mask is to play with it, play with it, play with it until you get it right. You're not going to adjust your strap tension one time and then be all done.

On the whole this mask seals very well with no leaks at the bridge of the nose like most other masks do. With minimal tension the mask does seal even at my high pressure of 15cm H2O. It also stays sealed through a very high range of motion of turning your head. It does not stay sealed if you contort your face like what might happen when your face muscles become very relaxed during sleep- those leaks that happen when you contort your face are the ones that must be compensated for by snugging up the straps.


Other full face masks are closer to a medical anesthesia mask with their design. This mask is closer to a dust mask or respirator with it's design. It's no wonder they use this mask in sports medicine because once you get it set up right you have an incredible freedom of movement and it doesn't lose it's seal at all. The only time when it does start to lose it's seal is if you really start to relax your face/jaw muscles and your face sort of pulls itself out of the mask in those areas. The key point with this mask is to keep playing with the strap tension until you find a balance between tightness and having too much leak potential. The mask will seal and hold it's seal through a wide range of movement with the straps tightened at a fairly low tension, but any kind of relaxing your jaw or contorting your face will cause a big leak. So you need to tighten the straps until those types of leaks don't happen anymore. If you wanted to, though, you could keep on tightening for every little leak until the mask got so tight that it was painful. You have to accept that a certain amount of relaxing or contorting your face will cause some leakage- but those kinds of movements hopefully won't happen while you're asleep.

This mask is fairly "sharp" and what I mean by that is the points of contact with high pressure are quite narrow. As a result this mask leaves a lot more red pressure marks on your face in the morning- they are the kind that go away pretty quickly, but they're there. The straps are sort of narrow, so likewise, those can tend to dig in especially on the back of your neck.

This mask would be awesome if you only had to wear it for two or three hours at most, or if you could get away with minimal tension on the straps. Unfortunately it's not perfect and you need to snug up until most of the leaks that happen with facial contortion are gone and that puts it just on the other side of comfortable. It's comfortable enough while you lay in bed falling asleep but by morning time your face has had enough and you really want to get it off. It does do it's job well. It seals very well with a moderate amount of strap tension. The amount of tension that I have to use is just a bit too much, and I really want it off in the morning, and it leaves red marks (but they go away fairly quickly.)"

"Mask is too hard at nose contact. Headgear fits too low on neck causing discomfort and changing mask tightness when head is moved back and forward."
