R&M International ResMed AirFit N30i Cushion - Replacement Cushion - Curved Nasal Cradle Mask - Small

A perfect replacement for my old one.

I was prescribed the F30i because I had some mouth breathing in my sleep study. I figured that since this thing was available for a great price here on Amazon, I'd see if I had mouth breathing because of the sleep apnea, or if I just breathe through my mouth because that's what I do.This piece is interchangeable with the P30i (but NOT the F30i - the attachment is completely different) and is relatively comfortable. Having never used a nasal only mask before, I did not realize how difficult it would be to learn to talk and yawn with this thing on. If you open your mouth while the CPAP is on, air just rushes right out of your mouth. It's kinda funny actually. As it turns out, I was mouth breathing because of the apnea. With this mask on, I don't have any mouth breathing. As I said, if you open your mouth (while relaxed) air just rushes out of it, so the one time I did roll on my back and open my mouth while I was asleep, I woke up immediately.At any rate, my only complaint about this mask is that the first few times I used it (once to see how it was, did not like it, didn't use it for like 2 weeks) it felt like it bruised my nose. It sits under the nose, across the nostrils, and kind of tugs up. I decided to try it a second time (acne from the F30i full face mask bothered me enough to give it another shot) and it was definitely less uncomfortable the second and third times. I now use this as my primary mask and hold the F30i for when I'm congested or just need a change.This is a fantastic mask (not a full mask, but it's the important part). I love the top-of-head hose connection. My sleep study used a mask with a nose hose connection and I woke up 4 or 5 times over night because I was tangled in that hose. That has never been a problem with this mask. I am a side sleeper, I can easily sleep on my side with it. There is slightly more noise with this than with the F30i (that thing is nearly silent), but I also got a P30i (the pillow version) and that thing is so loud I didn't even bother trying to sleep with it. It whistles incredibly badly. There's none of that with this thing. Give it a try. It needs the frame and headgear to make it work.

Excellent just as needed

Fit perfectly to my existing ResMed setup.

Very good
