I wouldn't be able to sleep with only a nose connection; all the air would go out of my mouth. I have no idea how it is possible for anyone to do that. However this piece creates an amazing, solid, dependable seal with my nose and I use it for awake sessions to breathe more fully and deeply and increase my inhalation depth as part of other exercises using a different mode of my device than the one that adapts and makes choices as I'm sleeping. Of course for that I use a full-face mask that is astonishingly good - the f20. That's the first mask out of at least twenty or twenty-five that actually holds during the night even under pressure up to 25 when it ramps up that far.

Just what I needed and it came quickly.

Best CPAP mask but it has been discontinued, which is so sad I have tired dozens. I am grateful that I found the last 3 available anywhere on the internet. Love

Not satisfied at all

Works well in keeping my pillows snug. Waited way to long to replace the old strap, so will be ordering 3 times a year now.

Mom and I love you guys, you are live savers

I think I’m missing something where the elbow connects to the frame seems to be two little holes there. It seems like there should be a filter over it or something. Air is coming out like an air hose, so I haven’t been using it. It’s a shame. Does anybody know what might be the problem?

Seems to fit pretty good, haven't had any problems with it slipping off.

Great machine, replacing an older model.
1800cpap made purchasing easy and I will be doing business with them in the future.

Best mask ever

.

At first I did not think this would fit my 3i, as it said on the website. I had also bought the lid for my 3i.
Both items were for the Elite 4i, but supposedly compatible. Since 3i parts were no longer available. I called customer support and they were patient, kind, and helped me work thru it. Her name was Alyssa. As I followed the steps to video the issues - lo and behold! - both 4i parts fit my 3i. Thank you.

Works great and everything I expected.

Finally a headgear and mask that fits great!!!! Please don’t ever stop with these! 20 year cpap user and it is the best…and I am a stomach/side sleeper. I was so confused about it sizing itself at first, then I discovered the little push on the mask and boom!💥 it self adjusts!!

Excelent product!!!
