  • Three sizes available – Small-Wide, Medium, and Large to match your current mask cushion size.

Description

The ResMed AirFit F40 Full Face CPAP Mask Cushion is the OEM Adaptiseal replacement cushion for the AirFit F40 mask — the direct swap when your current cushion starts to lose its seal, feel stiff, or show visible wear. Available in Small-Wide, Medium, and Large to match your existing mask setup exactly.

The Adaptiseal silicone design conforms to your facial contours to create a consistent, leak-resistant seal with minimal forehead and nose bridge contact. Replacing the cushion on schedule — every 1–3 months — restores the fit and seal performance of your mask without replacing the entire frame and headgear assembly, making it a cost-effective part of regular CPAP maintenance.

Product questions & answers

How often should I replace my AirFit F40 cushion?

It is recommended to replace the ResMed AirFit f40 mask cushions every 3-6 months to maintain an effective seal and optimal therapy. Silicone cushions tend to soften over time, and regularly replacing your f40 CPAP mask cushion helps ensure you continue to receive the benefits of an effective seal and optimal therapy from your CPAP device.
How do I clean my AirFit F40 cushion?
The AirFit f40 cushion, along with the vent ring, short tubing, and elbow, should be cleaned daily. It is recommended to refer to your AirFit f40 mask User Manual for complete cleaning instructions to ensure proper maintenance and longevity of your mask components.
What are the size options for the AirFit F40 cushion?
The ResMed f40 cushion is available in three sizes: small-wide, medium, and large, allowing users to find the perfect fit for their facial structure and achieve an optimal seal during therapy.
What is the material of the AirFit F40 cushion?
The entire f40 mask cushion is made of soft and comfortable silicone material. This silicone construction is designed to move and adapt to the contours of the face, providing and maintaining an effective seal throughout the night for a comfortable therapy experience.
Can I use a different size cushion with my existing F40 mask frame?
Yes, all ResMed f40 Masks use a single frame size, which means any AdaptiSeal Full Face cushion can be used with any F40 series mask frame. If you need to change the size of your mask, you can simply purchase a different cushion size and attach it to your existing f40 ResMed mask frame.
What is the AdaptiSeal technology in the AirFit F40 cushion?
The AdaptiSeal technology in the ResMed mask cushion ensures that the cushion rests securely under your nose and stays in place, no matter how you move during the night. It is designed to support compliance and provide a soft silicone cushion that adapts to the face and seals securely for an effective and comfortable therapy experience.
