Hi
I started out a few years ago, with my NHS-issued Respironics ComfortGel mask. On my search for a better mask, I found an on-line guide (no longer available, alas) which asked for various detailed facial measurements, and recommended a mask. It suggested the Respironics ComfortCurve which was a revelation.

As you can see from the pictures, it's fairly minimal, with the "business end" just sitting under my nose. There's one big hole that sits under both nostrils. The hose is a bit like a stethoscope with two tubes which join. That's been the only weakness in the design as the thin tubes eventually split. I loved the mask, and when I found it had been discontinued, I bought three spares. I also bought a Circadiance Sleepweaver Advance which fast became another favourite. But masks don't last forever.
My recent experiences have been by comparison very disappointing. I have looked for something similar to the ComfortCurve and bought an F&P Pilairo Q. I cannot get on with it. The nasal "pillows" are uncomfortable and although I might get used to them I feel as if I am not getting enough air. I've also tried the new Sleepweaver Elan. I really don't get on with that either... it feels like a big cloth "box" which doesn't sit well as I move around in bed. Oh Respironics, why did you stop makng the ComfortCurve?!
My local hospital continues to offer Respironics kit, and at my last CPAP "service" offered me a choice of another ComfortGel, or the GoLife. I took the GoLife, but it's very similar to the Pilairo and again I cannot get on with it.
It looks like the old Sleepweaver Elan is still available, but it's always good to have a choice of masks (a change is as good as a rest, as they say). I'm wondering what to try next - this is getting to be an expensive habit. I've read the review here of the Wisp, and that looks like a contender, but even then I'm not sure if I'd get on better with the silicone or fabric frame.
Any thoughts? For information I use a humidifier and used to have a fixed pressure of 9cmH2O but I now use an autoPAP machine (which I love).
Thanks,
Jonathan.
