Using your mask

When using your mask with ResMed CPAP or bilevel devices that have mask setting options, refer to the Technical specifications section in this user guide for the correct setting.

For a full list of compatible devices for this mask, see the Mask/Device Compatibility List here. If you do not have internet access, please contact your ResMed representative.

Use a standard conical connector if pressure readings and/or supplemental oxygen are required.


  1. Twist and pull both magnetic clips away from the frame.
  2. Ensure that the ResMed logo on the headgear is facing outwards and is upright. With both lower headgear straps released, hold the mask against your face and pull the headgear over your head.
  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. Pull the straps evenly until the mask is stable and positioned as shown in the illustration. Reattach the fastening tabs.
  5. Undo the fastening tabs on the lower headgear straps. Pull the straps evenly until the mask is stable and sits comfortably on the chin. Reattach the fastening tabs.
  6. Connect the device air tubing to the elbow. 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.

Cleaning your mask at home

Handwash your mask and headgear by gently rubbing in warm (approximately 86°F/30°C) water using mild liquid detergent. Rinse all components well under running water and allow to air dry out of direct sunlight.

  • 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.

Visible criteria for product inspection: If any visible deterioration of a system component is apparent (cracking, discoloration, tears etc.), the component should be discarded and replaced.

Daily/After each use:
  1. Disassemble the mask according to the disassembly instructions.
  2. Rinse the frame, elbow and cushion under running water. Clean with a soft brush until dirt is removed.
  3. Soak the components in warm water with a mild liquid detergent for up to ten minutes.
  4. Shake the components in the water.
  5. Brush the moving parts of the elbow and around the vent holes.
  6. Brush the areas of the frame where the arms connect, and inside and outside the frame where the elbow connects.
  7. Rinse the components under running water.
  8. Leave the components to air dry out of direct sunlight. Make sure to squeeze the arms of the frame to ensure that excess water is removed.
  1. Disassemble the mask. The magnets can remain attached to the headgear during cleaning.
  2. Handwash the headgear in warm water with mild liquid detergent.
  3. Rinse the headgear under running water. Inspect to ensure the headgear is clean and detergent free. Wash and rinse again, if necessary.
  4. Squeeze the headgear to remove excess water.
  5. Leave the headgear to air dry out of direct sunlight.


If necessary, slightly adjust the position of the mask for the most comfortable fit. Ensure that the cushion is not creased and the headgear is not twisted.

  1. Turn on your device so that it is blowing air.

    Adjustment tips:
    • With air pressure applied, pull the mask away from your face to allow the cushion to inflate and reposition onto your face.
    • 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. Do not overtighten as this may cause discomfort.
