Adjust straps evenly. The forehead support "anchors" your mask and should sit firmly on your forehead.

To achieve a comfortable fit using the AirFit™ P10, adjust the split-straps by spreading them apart to loosen, or draw them closer together to tighten.

Headgear may be too small. Additional headgear sizes are available to order separately.

If the mask includes a MicroFit dial, wind out the dial to position 24, where the forehead support is fully extended. Adjust in small increments until you achieve a comfortable fit that is not too tight.

Remove and refit your mask according to the instructions in the mask fitting guide. The headgear should sit at the crown of the head.

Check that the top and bottom headgear straps are correctly positioned.

Ensure that the Velcro tab is correctly aligned with the headgear material and not cutting into the top of the ear.

Check headgear positioning against instructions in the mask fitting guide. The headgear should sit on the crown of the head and not too far back.

Headgear may be the wrong size. Additional headgear sizes are available to order separately.

It is important to note that sizing across different masks is not always the same. The Quattro™ FX cushion is designed to sit mid-bridge (vs top-bridge like a conventional FFM). Talk to your clinician to have your face size checked against the sizing tool/fitting template.

  • Leak in eyes: Top straps
  • Leak on lip: Bottom straps

Turn off the CPAP or bilevel device and remove the mask. Refit your mask according to the instructions that came with your mask. Ensure that you position the cushion correctly on your face before pulling the mask down the face during fitting as this may lead to folding or curling of the cushion.
