Sizing for your AirFit F20

  1. You can print your ResMed sizing guide here. Remember to print to scale, as you’ll have to cut out your guide from the document you print.
  2. Once you have your sizing guide:
  3. use a mirror and hold the sizing guide to your face. The top of the guide should correspond with the top of your nasal bridge.
  4. the lower part of the guide indicates which mask size is best for your face. The size that aligns with the crease below your lower lip will be your recommended fit.
  5. If you’re between sizes, we recommend selecting the larger option for greater comfort.
  6. As an alternative to using a sizing guide, you can also use a straight ruler to measure the distance from the bridge of your nose (between your eyes) to the dip between your lower lip and your chin. Different measurements correspond to the following sizes:
  7. Between 74-86 mm: Small
  8. Between 86-98 mm: Medium
  9. Between 98-110 mm: Large
  10. Before purchasing or trialling the AirFit F20 mask, your CPAP provider will follow the same process using the sizing guide to help select the mask size that best fits you.

  3. Bring each of the magnets up to meet their corresponding clips on the frame.
  4. Adjust the tabs on the upper headgear straps.
  5. Adjust the tabs on the lower headgear straps.

Managing leak with your AirFit F20

  1. Leak often occurs when your mask’s seal is compromised by movement, incorrect fitting or improper sizing.
  2. To find a source of leak, run your finger along the edge of your mask’s seal. Once located, adjust your headgear.
  3. Resolve any leak in the upper part of your mask by adjusting your upper straps.
  4. Resolve lower mask leak with your lower straps.
  5. Do not overtighten as this may cause discomfort.
  6. If leak persists, with your device still switched on, reseal by briefly pulling your mask away from your face, letting your cushion reinflate, and resettling your mask cushion so the cushion membrane is sitting at the top of your nasal bridge.
  7. If leak continues, you may need a different size mask. Try our sizing guide or speak to your CPAP provider about using a different sized mask.

Maintaining your AirFit F20

  1. Your mask should be checked regularly for signs of damage and deterioration.
  2. When cleaning your mask, you should also check each component for damage. Your cushion, frame, tubing, elbow and headgear should all be regularly checked for cracks and tears.
  3. If any component of your mask is cracked or torn, it may be damaged and in need of replacement.
  4. We also recommend that you regularly replenish your mask cushion.
