Compact nasal mask

The ResMed AirFit N20 Nasal Mask has got a very nice soft cushion and nothing that comes in front of the eyes.

The other advantage of the N20 is that it has magnet clips to put it on and off. Its previous model, the N10 had magnetic clips too, but what we found with the N10 is that it pressed quite hard on people’s lips.

The N20 doesn’t have anything in front of the eyes meaning that in the little period before we fall asleep, nothing is in front of the eyes to block our vision.

Also, with the Mirage FX, we did have a little bit of a problem with the seal in here breaking after a period of time. The N20 has as a far simpler connection point meaning this issues does not exist any more.

Overall, we have found the N20 to be a much sturdier mask. We are getting a much better seal, it’s softer on the face, which in the end means you are getting comfortable, effective therapy.

  • InfinitySeal cushion made from silicone is designed to allow for movements and tolerate misfitting
  • Flexible material-lined frame allows breadth of fit and adds extra comfort
  • Magnetic clips allow for quick, easy fitting.
  • Plush, soft headgear allows a more comfortable night’s therapy
  • For Her version is also available.

An easy fit with the InfinitySeal technology

ResMed’s recent international study, showed AirFit N20 InfinitySeal cushion  fit 99.4% of faces.1
The uniquely, contoured silicone cushion will adapt to the profile of your face. The mask moves with you throughout the night. The secure fit and comfortable seal are designed for your needs.

Patient tested and preferred

The N20 has been back tested extensively and is an excellent chose for an over the nose mask.  ResMed’s latest study showed 75% of patients found the AirFit N20 was more stable compared to their current mask.

With unique cushion technology and a softer fabric frame, the N20 features combine to deliver an exceptional nasal mask –  71% of  patients tested said they preferred the AirFit N20 over the nasal mask they were currently using.

    I recently upgraded from an N10. The cushion is much softer and I find the mask much more comfortable. The magnets are making it much easier to use as well. Nice work ResMed

  2. Rated 3 out of 5


    very comfortable, easy to clean, only problem I have, is water accumulates often in mask through the night. hanging to dry the next day, only filling water to half way mark, doesn’t seem to do anything. cant fix it so I don’t get a goods night sleep.

    I find the N20 very comfortable and easy to keep a good seal all night. Doesn’t leave a mark on my face in the morning either.

    I was using a full-face mask but found this too cumbersome so switched to the N20. It works quite well and is comfortable. The magnetic clips are excellent.

    I love my new N20 nasal pillow mask ,it doesn’t leak,it’s not in the way ..I don’t have marks on my face in 6he morning.The only thing I have found because it’s new it’s leaving blisters on the bridge of my nose but once I put a soft bandaid on it ,it’s solved the problem.
    I’m so happy with it ,I love everything about it.

    i upgraded from a resmed activa which i have used for 13 years. Great product until it breaks, the nose cushion is hard to remove for cleaning, it broke from the base, very flimsy, and a magnet clip broke whilst i was sleeping (used for 2 weeks) Resmed replaced it straight away. otherwise I find it great can read in bed even have a drink.

    I have had the airfit n20 since mid February… man what a difference from my last mask…. I have tried numerous makes since being on cpap for approx 5 years and this is by far the best one yet. The magnets are a great touch and make it very easy…. the fact there is no straps towards the front of the face means I can have my mask on with my glasses when I read which means if I fall asleep I have my mask on and not fall asleep without it

    Great design! Easy to put on and take off, easy to clean. I found the nasal mask itself a bit too prone to leakage when laying on your side inspite of several adjustment attempts. A small annoyance but overall very comfortable and doesn’t leav those deep lines in your face after wearing it for the night like the standard strap type masks.
