ResMed AirFit F30i Mask cushion

The AirFit F30i Mask Cushion is a replacement ultra-compact full-face seal designed for active sleepers who use a tube-up-the-head mask configuration. Regular movement during sleep puts physical strain on a mask's seal, and older silicone can easily slide out of position, causing loud leaks and dropping therapy pressure. This replacement cushion restores the mask's intended sealing capability, sitting neatly under the nose and over the mouth to deliver quiet, consistent airflow regardless of your sleeping position.This component features an innovative minimal-contact shape that avoids the nasal bridge entirely, shielding you from top-of-the-nose skin irritation and pressure marks. The specialized interior design distributes air pressure evenly across the sealing surface, allowing the silicone to mold gently to your unique facial structure. Swapping out your old cushion for this fresh part helps preserve an efficient, leak-free system, ensuring your airway remains supported throughout the night.
