I originally bought the whole mask with the large nose piece but it seemed to leak occasionally because it was a bit too large. This medium was a good fit and no leaking. Price was good so in the future I will buy extra to save on shipping. Even with shipping this was 3 dollars cheaper then Amazon with free shipping. Delivery was okay.
I have only been on CPAP for three months. I had the res med pillow mask. It took me a while to fall asleep. If I had to get up to use the washroom then put it back on, I could not get back to sleep. I saw the new Air fit N 20 nasal mask. I ordered it and I could not be more happier! So comfortable. It's so easy to inhale and exhale. I have only had it for 4 days now I am able to get up if I need to, pop the hose back in and right back to sleep. I LOVE it. Definitely a 5 star mask.
