Your other 3/4 won't even know you have a mask unless she turns on a light, opens her eyes, and LOOKS at you.
This is one of THE POINTS of the Airfit P10.
There is a special defusing screen on either side of the tube that exhausts the air near silently.
It LOOKS like just very small pin holes placed close together, but likely they did a lot of turbulence modeling and testing to find the exact size to reduce noise and keep the air from streaming out.
You will be hard pressed to feel the air at even one inch away. Or to hear it at 3 (2.5cm to 7.5cm for you Swiss types

The vents are actually on the SIDE of the FRONT, but you aren't going to want to fool with any of that vent baffling; it isn't needed.
The only time I FEEL the air outside the mask is when I BURY my nose into a pillow, and even then there is not "stream of air" but rather a VERY slight "coolness" on my my upper lip of cheek or where ever the air escapes eventually.
To me, this coolness feels like a VERY SMALL and SILENT leak that is in no way uncomfortable.
Now that I know what that is, I just ignore it and snuggle into my pillow, but at first I would just move my head a little and it would disappear.

Anyone done an all night sound sampling or checked the exhaust feel late in the sleep session or on waking?
I have ramp OFF. I measure it mostly at 11 but when waking up I do investigate it at 12-14.
Although my pressure is only moderate, it doesn't change the sound noticeably even when at higher pressures.
It should be possible for me to just crank up the pressure and investigate....if that is really worrying you.

The pigtail hose is flexible enough (very light, very flexible) that it will route in any direction you need -- others have reported using it with various hose routing schemes including head gear.

Would vendor #1 sell you one? $99 free shipping (might be extra to Switzerland) and free RETURN INSURANCE? http://www.apneaboard.com/forums/Thread-CPAP-Supplier-List
