Step 1

How to size

Every size is in the box
No measuring — try them in order, keep the one that seals
XSSML
Start with Medium. It suits most adult faces. If you hear whistling or feel air on your top lip, size down. If you feel pinching or red marks in the morning, size up.
  1. 1
    Open the box and find the labelled cushions
    XS, S, M, L are bagged separately.
  2. 2
    Fit the starting size first
    Connect to your machine and lie down briefly to test the seal.
  3. 3
    Swap if it leaks or pinches
    Swapping takes seconds — cushions click on and off the frame.
  4. 4
    Reorder your winning size
    When it's time to replace, you only need that one cushion.

Step 2

Getting a good seal

A correct size plus light strap tension is the goal. Marks and leaks usually mean the cushion is the wrong size — not that you need to tighten more.

Fit tips for the ResMed AirFit P10
  • Ships with all pillow sizes (XS–L) — no template needed.
  • Pillows seal at the nostril opening, not inside.
  • Use the smallest that seals; swap sizes if you get leaks or marks.
Leak troubleshooting
Air on my eyes
Loosen the upper straps half a turn and shift the mask down a few millimetres. If it returns, try the next size down.
Whistling at the cushion edge
The cushion isn't fully seated. Lift it off your face, let it inflate, then lay it back gently — don't tighten.
Red marks on my cheeks or nose
You're over-tightening to chase a leak. The seal should work at "barely snug". Re-check your cushion size.
Mask shifts during the night
The top strap should sit high on the crown of your head. If it slides, lift the strap higher and re-snug evenly.
Step 3

Cleaning & care

Quick daily wipe, gentle weekly wash. Avoid alcohol-based cleaners — they degrade silicone.

Daily: detach the cushion and wipe with a damp cloth or mild soap and warm water; rinse and air-dry out of direct sunlight. Weekly: hand-wash the headgear and frame in warm soapy water and air-dry. Avoid alcohol, bleach and harsh detergents.
Step 4

Replacement schedule

Cushion: about every 1 month. Headgear: every 6 months. Frame: every 6 months. Replace sooner if the cushion tears, hardens or won't seal. General guide only — follow your clinician/supplier advice.

FAQ

Common questions

What size ResMed AirFit P10 do I need?
You don't need to pick a size — every cushion size ships in the box. Start with Medium (or the marked default) and swap if it leaks or pinches.
How often should I replace the ResMed AirFit P10 cushion?
About every 4 weeks. Silicone (and especially memory foam) absorbs facial oils and stops sealing properly — leaks that start "out of nowhere" are almost always a worn cushion.
How often should I replace the headgear?
Every 6 months, or sooner if the elastic loses its stretch. Worn headgear is a common hidden cause of leaks.
Can I use this with my current CPAP machine?
Most likely — modern CPAP / APAP / BiPAP machines from any brand work with any mask via the standard 22mm hose connector. Use the Mask Finder to confirm against your specific model.
Do I need a prescription?
In Australia, CPAP masks are available without a prescription — though we recommend buying through a clinician who can match the mask to your sleep study.
These are general guides — your clinician or sleep specialist can confirm what's right for you. We don't provide medical advice.
