Q: Is this cushion compatible with other ResMed masks?
A: No. This replacement cushion is designed exclusively for the ResMed AirFit™ F40 Full Face CPAP Mask and is not compatible with AirFit™ F20, AirFit™ F30i, or other ResMed mask models.
Q: How often should I replace the AirFit™ F40 cushion?
A: ResMed recommends replacing the cushion every 1–3 months, or sooner if it becomes worn, damaged, discoloured, or no longer provides a secure seal.
Q: How do I choose the correct cushion size?
A: Choose the same size as your current AirFit™ F40 cushion. It is available in Small, Medium, and Large to match your existing mask.
Q: Does the AirFit™ F40 cushion contain magnets?
A: No. The AirFit™ F40 AdaptiSeal™ Cushion is completely magnet-free, making it suitable for users who need or prefer a non-magnetic CPAP mask component.
