ResMed AirFit F40 Cushion – AdaptiSeal Full Face Cushion Replacement
The ResMed AirFit F40 Cushion is a replacement AdaptiSeal full face cushion designed for use with the AirFit F40 CPAP mask system. Replacing the cushion when signs of wear appear helps maintain a reliable seal and consistent CPAP therapy performance without the need to replace the entire mask.
This cushion is manufactured from soft, supple silicone elastomer and features a design with no hard parts, allowing it to adapt comfortably to facial contours. The flexible structure supports an effective seal while helping to improve comfort during sleep. Its lightweight construction and smooth surface also contribute to ease of use and routine maintenance.
The AirFit F40 cushion is easy to remove and replace as part of regular CPAP care. It is available in multiple sizes to support an accurate fit for different users. This product is supplied as a cushion only. The mask frame, headgear, and other components are sold separately.
Users should consult the official user guides for full information on contraindications, warnings, and precautions. Patients are advised to speak with their healthcare professional regarding the use of this medical device for the treatment of obstructive sleep apnoea.
