The Replacement Cushion for ResMed AirFit F40 Full Face CPAP Mask is designed to keep your CPAP therapy effective, comfortable, and leak-free. Over time, mask cushions naturally wear down, lose elasticity, and can start to cause air leaks — reducing the effectiveness of your treatment. To maintain optimal performance and hygiene, it’s recommended to replace your cushion regularly, especially if it’s damaged, losing its seal, or if you want to keep a backup on hand. This genuine ResMed replacement part ensures a perfect fit with your AirFit F40 mask frame, delivering the same comfort, seal, and quiet operation you expect from your original cushion. Small Wide, Medium, Large — all fit the same AirFit F40 mask frame. Key Features Genuine ResMed replacement designed specifically for the AirFit F40 Full Face CPAP Mask. Soft silicone seal adapts to facial contours for comfort and reduced skin irritation. QuietAir™ venting for a quieter, more peaceful sleep environment. Easy installation — snaps quickly into the mask frame without tools. Why Replace Your Cushion? ResMed recommends replacing full face mask cushions approximately every 3 month to prevent air leaks, maintain proper seal, and ensure hygienic CPAP therapy. Worn cushions not only affect comfort but can also compromise your prescribed therapy pressure. In the box: (1) Cushion
