InfinitySeal™ Nasal Cushion

The ResMed Airfit N20 Nasal Mask seal is suited to fit 99% of all unique facial structures and provides some of the best comfort for your sleep apnea therapy. With specially-designed loops and varied thickness, this design helps prevent leaks or blowout.  

Multiple Sizes Available

The AirFit™ N20 is available in multiple sizes and there is a size gauge available so you can determine which would be the best fit for you.

Soft and Flexible Frame/Magnetic Clips

The  AirFit™ N20 comes with soft plush headgear and flexible frame which sits underneath your eyes and allows clear visibility for those nights where you want to read a book or sit up and watch TV. The frames adapt to different face types while the integrated padding offers softness for a better nights sleep. One of the most popular features to the mask are the magnetic clips which guide the headgear to the frame quickly and easily.

Quick Release Elbow

The quick release elbow makes it easier for you to disconnect and reconnect the mask from the tubing without having to take the complete mask off, allowing you to get up during the night without having to worry about re-adjusting any straps.

How often should you replace the AirFit™ 20 mask?

In order for the mask to continue giving you the best sleep apnea therapy available, we recommend that you replace the silicone cushion every 1 month. Mask tubing should be every 3 months and headgear every 6 months.

The mask straps are not short enough for my small head. I have to remake the top of the mask to keep it from resting solely on my ears. It is a good thing I have a sewing machine and know how to remake the mask to fit more comfortably. It doesn't make any difference what type of mask I use, they are all just a little too big for me.

This is the most comfortable mask I've had yet. The strap placement is perfect for my face/head and the fitting card that you can print out got me a perfrect fit. When I wake up, I forget I'm wearing it sometimes.

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.

I have been using CPAP for approximately 7 years and tried several different nasal masks. Thought the Resmed Airfit N10 was fairly comfortable, however, bad leaks occurred when lying on my sides. Totally would NOT recommend. The new Airfit N20 has been redesigned, as well as headgear, with great comfort, without feeling the need to over tighten due to leaking and the best AHI I've ever achieved. Extremely pleased and I highly recommend this to anyone that prefer nasal masks. By the way, I have been a Respiratory Therapist for 36 years
