The mask comprises of a frame which acts as a holder for nasal pillows. The pillows are held in place by a larger pillow that surrounds the nose and inflates to spread the pressure over the entire surface of the nose and to align the nasal pillows. The mask almost does not need headgear except to stop the hose from pulling it off the face. The mask is one size, which works very well as it inflates to adjust to most nose shapes. The headgear is also currently one size, which is one of my major complaints with the mask.
I love the fit. I have a large nose that has been broken. This mask spreads the pressure over the entire nose. The mask stays on properly no matter what position I toss and turn at night, even when the mask is in contact with my pillow.
I hate the one size fits some. Not every head is the same size. I have a very large head and when you streach the elastic the pressure increases, and the mask is being crushed into my nose. If I release the pressure slightly it is so comfortable. An easy fix would be to have the head gear adjustable, possibly with a
Velcro section at the back of the head. Others that I have talked to have the opposite, a small head, then the elastic does not supply quite enough pressure. I have made the suggestion to F&P and received a nice reply. I am planning to purchase one after the trial and make my own adjustments to the headgear.
A second minor issue is the noise. I have a pressure of 14 and I find that there is a slight whistle from the mask. The noise occurs on breathing in. I use an S9 with an epr of 2. It may be the angle of the vent holes or a sharp edge that may be causing the noise. The noise can be reduced by repositioning the mask on the nose and may be partially caused by the pressure that the headgear is applying on the mask. This adjustment does not cause the pillows to leak.
The mask has a short hose extension that has a lot of flexibility in it's connections but I find that it does not have a smooth action and tends to knot rather than swivel. This is just a slight inconvenience and not a reason not to try the mask.
I feel that F&P will have a real winner here, right now it is for an average sized head. For the rest of us with larger and smaller heads, some adjustments to the head gear may be required.
