The Ultra Mirage Full Face Mask Replacement Cushion is the seal that fits onto the ResMed Ultra Mirage and Mirage Series 2 Full Face CPAP Masks. It's the component that rests against the face, covering the nose and mouth to maintain a steady airflow during therapy. A secure seal doesn’t need to feel tight. This cushion is made from soft, flexible silicone that gently conforms to facial contours without digging in or causing pressure points. Its shape supports a stable seal throughout the night, even if your sleep position shifts. Replacing the cushion helps keep your therapy consistent and prevents leaks that can affect sleep quality. It attaches quickly to the frame, making routine maintenance simple. Available in multiple sizes and designed specifically for the Ultra Mirage fit, it’s an essential part of keeping your mask working as it should.
