ENGLISH
Thank you for choosing the AirFit™ N20/AirTouch™ N20.
These masks are identical - except for the interchangeable
AirFit N20 silicone cushion and AirTouch N20 foam cushion.
This offers two choices for your mask, depending on your
preferred comfort, stability and seal. These masks may not be
available in all countries.
Using this guide
Please read the entire guide before use. When following
instructions, refer to the images at the front of the guide.
Intended use
The AirFit N20 and AirTouch N20 nasal masks channel airflow
non-invasively to a patient from a positive airway pressure
(PAP) device such as a continuous positive airway pressure
(CPAP) or bilevel device.
The N20 is:
•to be used by patients weighing more than 30 kg for
whom positive airway pressure has been prescribed
•intended for single-patient re-use in the home
environment and multi-patient re-use in the
hospital/institutional environment.
AirTouch N20 cushion
The AirTouch N20 cushion is intended for single patient re-use
in both the home and hospital/institutional environment and
recommended to be replaced monthly.
WARNING
Magnets are used in the lower headgear straps and the
frame of the AirFit N20. Ensure the headgear and frame is
kept at least 50 mm away from any active medical implant
(eg, Pacemaker or defibrillator) to avoid possible effects
from localised magnetic fields. The magnetic field strength
is less than 400 mT.
Clinical benefits
The clinical benefit of vented masks is the provision of
effective therapy delivery from a therapy device to the patient.
Intended patient population/medical
conditions
Obstructive pulmonary diseases (eg, Chronic Obstructive
Pulmonary Disease), restrictive pulmonary diseases (eg,
diseases of the lung parenchyma, diseases of the chest wall,
neuromuscular diseases), central respiratory regulation
diseases, obstructive sleep apnoea (OSA) and obesity
hypoventilation syndrome (OHS).
Contraindications
Use of masks with magnetic components is contraindicated in
patients with the following pre-existing conditions:
•a metallic hemostatic clip implanted in your head to repair
an aneurysm
•metallic splinters in one or both eyes.

2
Fitting your mask
1. Twist and pull both magnetic clips away from the frame.
2. With both lower headgear straps released, hold the mask
against your face and pull the headgear over your head.
Headgear check:
Ensure that the ResMed logo on the headgear is facing
outwards and is upright when the headgear is put on.
3. Bring the lower straps below your ears, and attach the
magnetic clip to the frame.
4. Undo the fastening tabs on the upper headgear straps.
Adjust the straps evenly until the mask sits comfortably
just over the nose. Reattach the fastening tabs.
5. Undo the fastening tabs on the lower headgear straps.
Adjust the straps evenly until the mask is stable. Reattach
the fastening tabs.
6. Connect the device air tubing to the short tube. Attach the
elbow to the mask by pressing the side buttons and
pushing the elbow into the mask, ensuring it clicks in on
both sides.
7. Your mask and headgear should be positioned as shown in
the illustration.
Adjusting your mask
If necessary, slightly adjust the position of the mask for the
most comfortable fit. Ensure that the headgear is not twisted
and for the AirFit N20 the cushion is not creased.
1. Turn on your device so that it is blowing air.
Adjustment tips:
−To resolve any leaks at the upper part of the mask,
adjust the upper headgear straps. For the lower part,
adjust the lower headgear straps. Adjust only enough
for a comfortable seal.
−The upper strap adjustment is the key to seal and
comfort.
−Do not overtighten the lower straps because they
mainly serve to keep the cushion in position.
Removing your mask
1. Twist and pull both magnetic clips away from the frame.
2. Pull the mask away from your face and back over your
head.
Disassembling your mask for cleaning
If the mask is connected to your device, disconnect the device
air tubing from the short tube.
1. Undo the fastening tabs on the upper headgear straps and
pull them from the frame. Keep the magnetic clips
attached to the lower headgear straps.
2. Remove the elbow from the mask by pressing the side
button and pulling the elbow away.
3. Hold the frame by placing your thumb over the side slot.
Pull the cushion away from the frame.
Reassembling your mask
1. Push the cushion into the frame. The frame has a shape
that allows you to insert the cushion only one way.
2. With the ResMed logo on the headgear facing outside and
upright, thread the upper headgear straps into the frame
slots from the inside. Fold them over to secure.

Cleaning your mask at home
It is important to follow the steps below to get the best
performance out of your mask.
WARNING
•As part of good hygiene, always follow cleaning
instructions and use a mild liquid detergent. Some
cleaning products may damage the mask, its parts and
their function, or leave harmful residual vapours that
could be inhaled if not rinsed thoroughly.
•Regularly clean your mask and its components to
maintain the quality of your mask and to prevent the
growth of germs that can adversely affect your health.
CAUTION
Visible criteria for product inspection: If any visible
deterioration of a system component is apparent (cracking,
crazing, tears etc), the component should be discarded and
replaced.
Once you have disassembled the mask, clean the components
as follows.

each use)
1. Soak and agitate the AirFit N20 cushion, elbow and short
tube in warm water (approximately 30°C) using a mild
liquid detergent for up to 10 minutes.
2. Clean the components with a soft bristle brush, paying
particular attention to the small vent holes on the elbow.
3. Thoroughly rinse the components under warm flowing
drinking quality water.
4. Inspect each component to ensure that they are visually
clean and free of detergent residue. If required, repeat
washing.
5. Allow the components to dry out of direct sunlight before
assembling.
Headgear, frame (Weekly)
The magnetic clips on the frame can be left on for washing.

CAUTION
•The cushion must not be submerged in liquid as this
may damage the cushion and affect mask
performance.
•Discard the cushion if it is submerged in liquid or
heavily soiled.
•Do not expose the cushion to domestic cleaning
products or cleaning devices.

4
You do not need to clean the AirTouch N20 cushion every day.
It is recommended to replace your cushion every month. If any
visible deterioration of the cushion is apparent, the cushion
should be discarded and replaced. If required, wipe the
outside of the foam cushion with CPAP wipes or similar
alcohol-free wipes and allow to dry. Do not store or place the
cushion in direct sunlight.
Troubleshooting
Problem/possible cause
Solution
Mask is too noisy.
Vent is dirty.
Clean the vent according to the instructions.
Mask is incorrectly assembled.
Disassemble the mask, then reassemble
according to the instructions.
Elbow and short tube
incorrectly installed
Remove the elbow and short tube from your
mask frame, then reassemble according to the
instructions.
Mask is leaking. Refit or reposition your mask.
Readjust the headgear straps to bring the mask
closer to the face and improve your seal.
Check that your mask is assembled correctly.
Mask leaks around face.
Mask is not positioned
correctly.
Check that the mask size indicator is facing
downward on the bottom of the cushion along
the bottom of your nose.
Mask may have been fitted
incorrectly.
Pull the mask away from your face and
reposition, ensuring that the lower corners of
the mask fully enclose your nose. If necessary,
readjust the headgear straps to keep the mask
in the right place.
Cushion may be dirty.
Clean the cushion according to the instructions.
Problem/possible cause
Solution
(For AirFit N20 only) Cushion
membrane is creased or
folded.
Remove and refit your mask according to the
fitting instructions. Ensure that you position the
cushion correctly over your nose before pulling
the headgear over your head. Do not slide the
mask down your face during fitting as this may
lead to folding or curling of the cushion.
Cushion is not positioned
correctly.
Reposition the mask on your face. If leak
continues, turn off device, resettle your cushion
and then turn device back on.
(For AirTouch N20 only)
Cushion is nearing the end of
its life
Cushion performance may deteriorate as the
foam nears the end of its lifespan. Adjust your
headgear and if the problem persists, replace
the cushion.

correctly.
Ensure that the headgear straps are not
overtightened or too loose. You may find that
this mask does not need to be tightened as
much as other nasal masks.
Check that the headgear is not twisted.
Mask may be the wrong size. Talk to your clinician to have your face size
checked against the fitting template. Note that
sizing across different masks is not always the
same.
