I don't know if it's because I have a deviated septum or weird shaped nose or what, but no matter how tight I get the P10 on, it always still leaks out of my left nostril. Loudly... hissing and whistling. And that is with the large ones. I've had a couple of nights right after I wash it where it's been OK, but mostly it's a nightly game of "is it tight enough?".
My AHI is up to 3 with the P10 (it was < 1 with the Wisp) and I just can't seem to consistently get the mask on tight enough. My large leaks are usually at 12-17%. I feel like a truck hit me and I have a headache when I wake.
I've given it 2 weeks. I've changed the cushions and I've washed them every day. Nothing seems to work.
Sadly, it's just not the right fit for me
I'll let you know how it goes now that it's cooler. ( I think the heat has contributed to the rash)
