ResMed AirFit F40 Full Face Mask Cushion

ResMed AirFit F40 Full Face Mask Cushion (AdaptiSeal™)

Soft. Secure. Designed for Comfort.

Overview

Upgrade or refresh your AirFit F40 Full Face Mask with a genuine AdaptiSeal™ replacement cushion from ResMed. Made from ultra-soft silicone, the F40 cushion is designed with a minimal-contact shape that seals below the nose and around the mouth — reducing pressure points and eliminating contact with the nasal bridge or upper cheeks.

Perfect for comfort-seekers and side sleepers, the AdaptiSeal cushion adapts to your unique facial structure to provide a secure, leak-free fit all night long.
