ResMed AirFit F10, Quattro FX & Mirage Activa LT Discontinued: What It Means and Your Replacement Options
If you have been using the ResMed AirFit F10, Quattro FX, or Mirage Activa LT for years, discovering that your mask has been discontinued can feel frustrating. Many CPAP users stay with the same mask for a long time once they find a fit that works.
ResMed has officially retired these legacy models as part of its normal product lifecycle. The good news is that clear manufacturer-recommended replacements are available, and most users transition smoothly to the newer platforms.
Below is a breakdown of what has been discontinued, what replaces it, and how sizing compares.
Which ResMed Masks Have Been Discontinued?
The following models are no longer in production:
- ResMed AirFit F10 Full Face CPAP Mask
- ResMed AirFit F10 For Her Full Face CPAP Mask
- ResMed Quattro FX Full Face CPAP Mask
- ResMed Quattro FX For Her Full Face CPAP Mask
- ResMed Mirage Activa LT Nasal CPAP Mask
If you are currently using one of these masks, you will need to transition to the updated platform once replacement stock is no longer available.
What Replaces the AirFit F10?
ResMed transitioned F10 users to the AirFit F20 platform.

AirFit F10 → AirFit F20

The F20 platform maintains a similar sizing structure while incorporating updated cushion technology and frame design.

If you previously used a Large or Large Wide Activa LT, you may need to review sizing carefully before ordering.
Printable sizing guides are available on product pages to help confirm fit before purchasing.
Why Did ResMed Transition to the F20 and N20 Platforms?
ResMed’s newer generation masks, including the AirFit F20 and AirFit N20, were developed with updated materials and design features intended to improve seal consistency and long term comfort.
These platforms include:
- Adaptive InfinitySeal cushion technology
- Improved frame flexibility
- Updated magnetic clip system
- Simplified frame to cushion compatibility
One important structural change involves frame and cushion sizing.
With older masks such as the F10 and Quattro FX, the frame size and cushion size were often linked. This meant that if your cushion size changed, you might need to purchase an entirely new mask system to match the correct frame.
With the newer F20 and N20 platforms, a single standard frame size is compatible with multiple cushion sizes. For example, if you purchase a Medium cushion and later determine that a Large cushion provides a better seal, you typically only need to replace the cushion rather than the full mask system.
This design simplifies sizing adjustments and can reduce the need to purchase a completely new mask when refining fit.
Will My New Mask Work With My Current CPAP Machine?
Yes.
All standard CPAP masks use the industry standard 22 mm hose connection. You do not need to replace your CPAP machine when upgrading from F10, Quattro FX, or Activa LT to their newer equivalents.
Exception
The ResMed AirMini Travel CPAP uses proprietary tubing and requires AirMini specific masks or adapters.
Frequently Asked Questions
Can I still get replacement parts for the F10 or Quattro FX?
Availability depends on remaining distributor stock. Once cushions and frames are depleted, transitioning to the newer platform will be necessary.
Will the F20 or N20 feel different?
Yes, slightly. While sizing is similar, cushion materials and frame design have been updated. Most users adjust quickly, but reviewing sizing guides is recommended.
Final Thoughts
Mask discontinuations are a normal part of product evolution. While it can be inconvenient to move away from a model you are comfortable with, ResMed’s recommended transition pathways are designed to maintain fit consistency and improve performance.
If you are unsure about sizing, compatibility, or whether to explore a different mask style altogether, guidance and sizing tools are available to help make the transition smooth.
