Product Description
Ultra-Compact Comfort and a Secure Seal
The ResMed AirFit F40 transforms full-face CPAP therapy by utilizing an innovative, under-the-nose design. Instead of sitting heavily over the bridge of your nose, the adaptive silicone cushion rests gently beneath it while securely covering your mouth. This minimal-contact approach eliminates uncomfortable pressure points and morning red marks, while providing an unobstructed field of vision so you can comfortably read or watch TV before falling asleep.
Flexible Support for Active Sleepers
Designed to move with you, the fully flexible frame adapts seamlessly to the contours of your face throughout the night, making it an ideal choice for active and side sleepers. The frame is softly padded to prevent skin irritation and features integrated magnetic clips for effortless assembly. Additionally, the included short tube boasts a quick-release elbow and QuietAir™ diffused venting, allowing you to easily disconnect from your machine in the dark and ensuring a whisper-quiet sleep environment.
Hassle-Free Maintenance Without a Prescription
Refreshing your CPAP setup is simple and straightforward. Under FDA guidelines, purchasing individual replacement parts like this frame and cushion combination without the headgear does not require a prescription, saving you time and hassle. This kit provides the core components of the AirFit F40 system—just snap on your existing headgear, connect your standard CPAP hose, and you are ready to enjoy a rejuvenated, leak-free seal.

Key Features
Upgraded comfort and freedom of movement for a better night's sleep
- Under-the-Nose Cushion Design: The minimal-contact silicone cushion rests gently beneath your nose, eliminating red marks on the nasal bridge and keeping your field of vision completely open.
- Fully Flexible Frame: A soft, fabric-padded frame bends and adapts seamlessly to your facial contours, making it highly accommodating for side sleepers and active sleepers.
- QuietAir™ Diffused Venting: The exhalation port gently and quietly disperses air, eliminating drafts and minimizing noise so both you and your bed partner can sleep soundly.
- Triple-Swivel Short Tube: The included extension tube features three distinct rotational points to prevent your CPAP hose from binding, kinking, or dragging as you change positions in bed.
- Integrated Magnetic Clips: The frame comes equipped with magnetic clips so you can easily and quickly snap your existing AirFit F40 headgear into place.
- Anti-Asphyxiation Safety Valve: A built-in safety flap automatically opens if your CPAP machine loses power, allowing you to safely breathe room air.
- Prescription-Free Convenience: Because this replacement kit is sold without headgear, it does not require a prescription under FDA guidelines, making it fast and easy to refresh your mask components.
AirFit F40 Setup and Demonstration
- Machine Setting Requirement: ResMed recommends changing your CPAP machine's mask setting to "Pillows" mode rather than "Full Face" to ensure the algorithm tracks therapy accurately with the F40.
- Triple-Swivel Hose Design: The short extension tube features three distinct rotational swivel points to completely prevent the hose from binding or kinking when shifting positions in bed.
- Power-Outage Safety Flap: The frame incorporates an integrated anti-asphyxiation valve that automatically opens if the CPAP machine loses power, allowing safe room-air breathing.
- Hidden Size Indicators: The cushion's size letter (SW, M, or L) is concealed on a clear tab that is only visible when the silicone cushion is completely detached from the outer frame.
- Fit Nuances for Narrow Noses: Users with particularly thin or pointy noses may be more prone to experiencing minor air leaks at the front tip/valley of the cushion, and must ensure the center silicone dividing membrane is centered so it does not shift and cover a nostril.
