ResMed Aifit N20 – Ultimate comfort and performance

The ResMed AirFit N20 Nasal CPAP Mask features the InfinitySeal cushion – which ResMed claims is the most adaptive they have ever designed – along with a soft and flexible frame that includes integrated padding. The result is a mask designed to comfortably move with you and provide a reliable seal throughout the night, regardless of sleep position.

Key AirFit N20 features:

  1. InfinitySeal cushion was shown to fit 99% of all faces in internal ResMed studies.
  2. Quick-release elbow makes it simple to disconnect from the tubing without removing the mask.
  3. Plush headgear is specifically designed for extra softness and stability.
  4. Soft and flexible frame sits underneath the eyes and adapts to different facial types, while its integrated padding provides added softness.
  5. Magnetic headgear clips guide the headgear to the frame quickly and easily.

A recent ResMed internal study conducted internationally showed that the AirFit N20 CPAP Mask fitted 99% of patients; they may well have achieved that target. Please ensure you use the sizing gauge in the Downloads section to ensure you get the correct size and maximise your opportunity to get a comfortable fit from the InfinitySeal cushion.

The headline advancement with the mask over previous ResMed nasal CPAP masks is the new InfinitySeal, a cushion that works by inflating towards the face. This balloon-type seal allows the mask to move and adjust as required rather than be a rigid, defined shape, and can, therefore, more easily adapt to different facial variables and position changes during the night. In addition, the frame also has a degree of flexibility, so the entire mask is better able to compensate for movement and adjustments when required.

A full range of spare parts are available

The AirFit N20 has a number of improvements over the previous AirFit N10 when it comes to durability, but no mask lasts forever. It is reassuring to know that every part of the mask can be replaced if and when necessary.

The ResMed N20 small mask comes with small headgear & the medium and large masks come with the standard (medium) headgear. If you require a smaller or larger headgear you can find all replacement parts for the N20 here.


AirFit F20 Full Face CPAP Mask is also available

Like the sound of the N20 but require a full mask? The AirFit F20 incorporates many of the same key design aspects of the N20 but in a full-face format. Even if you are predominantly a nasal CPAP patient, having a full face mask on hand in case, you get a cold or similar will allow you to continue to benefit from CPAP therapy. The F20 would provide a natural backup to your N20 in such a circumstance.

Due to the magnets used in this mask, it should not be used by patients that have implanted devices that may be affected by magnets. This extends to those with household members, caregivers, and bed partners that may be in close vicinity to the masks. Such devices include but not limited to:

* Pacemakers
* Implantable cardioverter defibrillators (ICD)
* Neurostimulators
* Magnetic metallic implants/electrodes/valves placed in upper limbs, torso, or higher (i.e. neck and head)
* CSF (cerebral spinal fluid) shunts (e.g., VP (ventriculo peritoneal) shunt)
* Aneurysm clips
* Embolic coils
* Intracranial aneurysm intravascular flow disruption devices
* Metallic cranial plates, screws, burr hole covers, and bone substitute devices
* Metallic splinters in the eye
* Ocular implants (e.g., glaucoma implants, retinal implants)
* Certain contact lenses with metal
* Implants to restore hearing or balance that have an implanted magnet (such as cochlear implants, implanted bone
conduction hearing devices, and auditory brainstem implants)
* Magnetic denture attachments
* Metallic gastrointestinal clips
* Metallic stents (e.g., aneurysm, coronary, tracheobronchial, biliary)
* Implantable ports and pumps (e.g., insulin pumps)
* Hypoglossal Nerve Stimulators
* Devices labeled as MR (magnetic resonance) unsafe
* Magnetic metallic implants not labeled for MR or not evaluated for safety in a magnetic field

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.

How often should I change my AirFit N20 cushion?

CPAP masks need to be cleaned daily to remove bacteria, and oil build-up transferred from your skin. The cushion should be changed every six months or when it starts to show wear and tear. To get the most from your AirFit N20, change the mask parts when necessary, so you do not need to buy a whole replacement mask.

What mask type is AirFit N20?

The AirFit N20 is a nasal CPAP mask designed for users who breathe through their nose while sleeping.

How do I clean my AirFit N20 cushion?

Begin by disassembling your Resmed N20 and use warm water and soap to soak your CPAP cushion. You should clean your mask cushion daily.

How long does an AirFit F20 mask last?

If you take care of your mask, regularly clean it and replace parts, it should last between 6 to nine months.

Will I be able to us the Airfit N10 with my CPAP machine?

The Resmed Airfit N10 will be compatible with all CPAP machines on the market.

Do Resmed provide any alternatives to their Airfit N10 Nasal mask?

Resmed offer a number of alternatives to the Airfit N10, such as their Airfit F10 offering a full face mask option as well as the Airfit P10 nasal pillow mask for those looking for alternatives.

How do I know which size of the Airfit N10 is right for me?

Resmed have provided us a sizing guide that is available for you to download, you can find this guide in the Downloads tab on this webpage.

How do I keep my Airfit N10 clean on a regular basis?

It is recommended that you regularly wash your Airfit N10 in warm soapy water before and after usage to keep the mask clean. We would advise against using any antibacterial or bleach based soaps as this can degrade the silicone cushion of the mask.
