Maintain structure, fit, and airflow performance with the ResMed AirFit F40 Frame. Designed for the AirFit F40 full face mask, this soft, flexible frame forms the foundation of the system—holding the cushion and headgear in the correct position to ensure a stable seal and consistent airflow.
 
With a universal one-size design, the frame is engineered to adapt to different facial shapes while maintaining alignment across compatible cushion sizes. Lightweight and low-profile, it supports the F40’s streamlined feel, reducing bulk while allowing natural movement during sleep.
