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.

ResMEd masks seem to get a lot of love and after buying the N20, I agree. It's well made but also lightweight. Secures/seals well and is also comfortable. Highly recommend.

I was looking for a mask to upgrade from the AirFit N10 and figured checking out the N20 was the logical next step. AirFit products have always been quality for me so I had no fears about purchasing the N20. It was advertised as being quieter and more comfortable, and so far it’s lived up to those promises.

The nasal cushion is excellent, it seals just as well as my N10 one did. I would also argue it’s more comfortable and holds on better. Before I would occasionally have slippage on off nights but I haven’t had any of those wit the N20. The new diffuser design is also whisper quiet which is great for me and my partner.

The frame is also great. It’s well-padded, lightweight, and spreads out the pressure evenly. It also holds on very well and is a cinch to take off thanks to the quick release mechanism. The elbow has quick release tabs too so it’s easy to eject the hose when you have to do a quick errand. It’s been easy to adjust and as such, I haven’t had any issues with fit and feel. Make sure to use the size gauge to find the right size cushion for you.

Long time Airfit F20 here, I’m a huge advocate of Resmed products. Decided to give nasal masks a try recently and naturally, I picked up the N20. So far it’s been great, all the glory of the F20 with an excellent nasal cushion.

The features that made the F20 my favorite mask are here as well. Magnetic clips make taking the mask off a cinch, and helps prolong the longevity of the Velcro straps. Headgear is soft, light, breathable, and fits well. Well designed to hold the head and mask in place. Quick release elbow on the air feed tube is probably your quickest way to disconnect for midnight excursions.

Of course, the part that changed for me is that the N20 is a nasal cushion rather than full face. Resmed really makes great cushions and these are no different, supremely comfortable. Fits without issue, didn’t have any leakage issues from day 1. Sizing gauge on Respshop was very accurate as well, I’m very certain that I picked up the right size cushion right off the bat. Easy to clean too, I just run it under some warm water and let it air dry. They recommend that you replace the cushion every month but my experience is that it can last some time longer than that.

Resmed is always top of the class in my opinion. The N20 is just another excellent product in their lineup and it’s quickly even supplanting my longtime F20 as my favorite mask. You can’t go wrong either choice.

I'm pretty new to the whole CPAP thing, but I heard good things about the Airfit N20 from some of my buddies and decided to give it a try. First things first, this mask was a little on the uncomfortable side for me. In all honesty, this might be because I'm new to CPAP in general, so take my experience with a grain of salt.

Otherwise, I would say this mask is pretty ideal for me. Setting up the mask was very intuitive even for me, and I'm able to use my mask without much trouble when I browse my phone before bed. The mask definitely does its job when I'm sleeping. I usually set my pressure on the lower end, and I haven't noticed my mask leaking yet. Also, I sleep on my back, but I haven't really noticed any lines on my face in the morning. A lot of my friends talked about that, so I feel lucky to not really be experiencing that problem.

I'm still on the search for a more comfortable mask, but for now, I'll continue using my Airfit N20. I'm pretty happy with this mask.

Like the product very well lightweight easy for a night but being a mouth breather have a hard time with the chinstrap. If there was a way to add a chinstrap to the mounting piece it would be fabulous.

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

Does this mask work ok for people who sleep on their side? (Asked on 04/10/2021)
Yes, it has a pretty small profile so it should work okay. Some side sleepers prefer a mask with the tube on the top such as the DreamWear or N30i however, while others don't. It's really a personal preference!
