AirFit N30i – ResMed’s most adaptable mask to date

The AirFit N30i from ResMed is an under-nose mask.  This makes it easier to seal; a smaller contact area means less risk of leakage. The minimal-contact design gives you the freedom to move into any sleeping position comfortably.

The N30i is one of the latest in the AirFit range of nasal masks but has little in common with the masks before. 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 your 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 Resmed N30i frame 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 focuses on patients who change position regularly or spend most of the night on their side. The AirFit N30i’s flexibility and hose positioning is particularly beneficial for those who frequently move in sleep.

The N30i also has QuietAir technology integrated into the mask. The QuietAir elbow reduces noise by 89% and makes exhaled air leave the mask 70% more gently. This reduces noise levels emitted from the mask, minimising disturbances for both the wearer and their bed partner.


Sizing your ResMed AirFit N30i

There are two starter packs, each of which is delivered with 1 frame and 1 cushion as follows:

  • Small starter pack: 1 small frame and 1 small cushion
  • Standard starter pack: 1 standard frame and 1 standard cushion

Please note: the standard frame is bigger than the smaller frame. Generally, most men should select the standard frame, and most women should choose the small one. See below for more information on this.

Additional cushions can be ordered as spare parts:

  • Small wide cushion (SW size): for small, flat noses
  • Wide cushion (W size): for large, flat noses

Please note that these cushions must be purchased separately if required; ResMed does not include them as standard. See the guides below for more information about sizing.


Sizing your ResMed AirFit N30i frame

Step 1 – In general, men should select the standard frame size, and women should select the small frame size. These general recommendations can be disregarded if you feel you have a smaller/larger face than average.

Step 2 – The frame should sit on the top of the head, like a headband. If the frame is too small, it will feel tight and sit too close to your forehead. If the frame is too large, it will feel loose and sit too far back on your head.

Cushions are also available in Small, Wide (for small flat noses), and Wide (for large flat noses). Should one of these additional sizes be required, it can be ordered here – they will automatically be half-price when ordered at the same time as the N30 itself. Use the guide below to determine if you need one of the additional sizes.


Sizing your ResMed N30i cushion

Step 1 – Download the N30i Sizing Guide. Print it in the right dimensions (check the scale).

Step 2 – Place the template below your nose, perpendicular to your face. If you have a narrow nose, start with the blue/red side of the template. If you have a wide nose, start with the black/purple side of the template.

Step 3 – Look into a mirror and assess whether your nose falls inside or outside the margins on the template. If you are between two sizes, choose the larger one.

Step 4 – If your nose is size S (red) or M (blue), select the appropriate cushion from your starter pack. If your nose is SW (purple) or W (black), then you will need to order the cushion in addition to a starter pack; ResMed does not include these as standard with either pack.


Who is the N30i suitable for?

Nasal breathers: This mask is designed to deliver air through the nostrils, making it far more suitable for individuals who breathe through their nose.

Side sleepers: This mask is ideal for those who prefer to sleep on their side due to its minimalism and small scale.

Claustrophobia: If you are someone who experiences claustrophobia and prefers minimal facial coverage, this mask is a great choice. The freedom and clear line of sight provided by this mask make it comfortable for individuals who may feel restricted by larger masks.

Facial hair: Nasal masks are ideal for users who have a beard or moustache, as they offer a far better seal than a full face mask.

Adapting to your mask can take time, and you may not experience the effectiveness straight away. Facial features, Sleep Apnoea severity and personal preferences can all play a role in deciding which mask is right for you. It is recommended to discuss which mask you require with your healthcare provider or sleep specialist so you can gain the most from your therapy.

Mask Fit Insurance is available for this mask

If you are considering trying this mask for the first time, you can order in confidence using Mask Fit Insurance.

Mask Fit Insurance costs £14.99 for nasal masks and £19.99 for full face masks, and allows you to return this mask for a refund if unsuitable.

You have 28 days from the dispatch date to assess the mask and notify us that you are unhappy with it for any reason. You can return it and have it refunded (we must receive it back within 7 days of being notified).

The fee for the insurance is non-refundable once the mask is opened, as are any outgoing postage costs. The mask itself will be refunded in full.

A pre-paid returns label will be included for customers in the UK. We strongly recommend getting a proof of postage (which is free) as returns not received cannot be refunded. For overseas customers, the return postage will need to be arranged by the customer and this cannot be reimbursed.

CPAP masks purchased without insurance cannot be returned/refunded once opened for hygiene reasons, as explained in our returns policy.

Mask Fit Insurance must be ordered at the same time as the mask in question, and cannot be added retroactively.

Intus Healthcare reserve the right not to honour any orders containing multiple masks purchased with Insurance; please instead choose which mask you feel is most suitable and select the size required as per the sizing gauge (if applicable). Should you subsequently determine a different mask or size is required, you can of course return the first and order the other.

If you need any further information, please use the chat function (if available), or contact us.
