The AirFit N30i is a nasal cradle mask from ResMed which gives the freedom to sleep in any position. The discreet, minimalist design features a convenient top-of-the-head tube design, a comfortable nasal cradle cushion and a self-adjusting frame for a stable fit.



AirFit N30i Nasal CPAP Mask

The AirFit N30i from ResMed is an under-nose mask, and is very similar in design to the popular DreamWear mask from Philips. Unlike a typical nasal mask, the Resmed AirFit N30 sits underneath the nose, rather than around it. This makes it easier to seal; a smaller contact area means less scope for leakage. The bottom of the nose is also more flexible, being primarily cartilage rather than the bone of the nasal bridge, making it easier to adjust a mask to.

As well as using an under-nose cushion, the CPAP tubing now connects on the drop of the head rather than the front of the mask. This significantly improves freedom, with the tubing far less likely to be pulled when changing position. It also reduces the weight of the front of the mask, reducing the effects of gravity when sleeping on your side.

The N30i is also entirely flexible; the frame itself is flexible (on most masks this is rigid), allowing a degree of automatic adjustment throughout the night. Every aspect of the AirFit N30i's design is focused on patients who change position regularly, or who spend the majority of the night on their side. The AirFit N30i's flexibility, and hose positioning, are particularly beneficial in such instances.

What our customers say

Beechfield Sleep is an excellent company. They're reasonably priced and have a great range of products.

My patient manager Rosin is very well informed and provides a great back up service. She is always there at the end of the phone or to call out. I feel very safe with Beechfield Sleep.

Edel Gallagher

I am delighted with the CPAP machine from Beechfield Sleep. I have been using it for over a month and even after the first night of using it, I couldn't believe how well I slept. It's fantastic to wake up feeling well-rested & refreshed. Thanks for the demonstration and information, you explained everything perfectly and I felt very confident using it on the first night and thereafter. It's also great to have you at the other end of the phone if I've any questions or concerns.

Jenny Sheridan

Thank you so much for all your help. After years of feeling exhausted, it's great to wake up feeling like I've actually slept. I would like to pay special thanks to all the staff who really explained everything in detail and who have been at the end of the phone for my constant questions! They have shown unbelievable patience, especially in getting the right mask! Thanks again, this has been life-changing
