AirFit F40 Replacement Schedule & Compatibility
AirFit F40 Replacement Schedule
Worn mask parts leak, lose their seal, and irritate skin. Replace on this schedule:
| Part | Replace every | Why |
|---|---|---|
| Cushion | 1 month | Silicone softens and loses its seal with nightly use |
| Headgear | 6 months | Stretched headgear forces overtightening and pressure sores |
| Complete mask | 6-12 months | Frame components wear out with daily handling |
What Fits the AirFit F40
The F40 is ResMed newest compact full face mask - it seals under the nose rather than over it. F40 cushions and headgear fit only the F40 frame. F20 and F30 parts will not fit. Cushions come in Small, Medium, and Large.
FAQs
How often should I replace my AirFit F40 cushion?
Every month. A worn cushion is the top cause of leaks and morning face marks.
Will F20 or F30 cushions fit the F40?
No. The F40 uses its own compact under-the-nose cushion design. Only F40 parts fit the F40 frame.
What sizes do F40 cushions come in?
Small, Medium, and Large. Match the size printed on your current cushion.
Why choose the F40 over the F20?
The F40 is smaller and lighter, seals under the nose, and gives a clearer field of vision - while still covering the mouth for mouth breathers.
Do I need a prescription to buy F40 parts?
No. Cushions, headgear, and replacement parts require no prescription.
How fast do F40 parts ship?
Orders ship fast from the US. Shipping is free on orders over $99.
