Smartly designed air diffusion ports for exhaled air 360-degree elbow and Tube Swivel Set-it-and-forget-it headgear clips Minimal Contact Points The Quattro FX design creates a more secure seal without a forehead support system. This innovative approach to design provides the Quattro FX Full Face CPAP Mask user with complete freedom. Freedom that comes from a clear line of sight-read a book, watch TV, or simply enjoy the view. Spring Air Technology The patented Spring Air technology creates a type of 'shock absorber' between the Spring frame and Spring Air cushion. These features coupled with the ergonomic headgear, work together to eliminate the need for a forehead support. In summary, the entire system works to create comfort, while providing a soft, stable mask during sleep. Dual-Wall, Spring Air Cushion The Mirage FX generation of masks uses a revolutionary design that provides comfort and stability. The dual-wall design takes an inner and outer approach to maintain the seal. The soft inner supportive layer stabilizes the cushion. The outer membrane reduces leaks and pressure points. As airflow increases into the cushion, the outer membrane inflates to surround the nose, as opposed to stretching over it. Swing Seal Technique The ResMed Quattro FX Full Face mask uses a new Swing Technique to create the perfect fit. The Swing Seal technique is the result of the Spring Air technology and the dual-wall membrane that surrounds the bridge of your nose. In summary, as the air enters the mask it slowly inflates and adapts to your facial contours. With the straps unattached, simply place the mask at the bridge of the nose. For there, you slowing drop the mask into place on your face. Once it is place, simply attach the straps to your comfort. There is no need to re-adjust the mask after this. We have provided a video that walks you through this process. For Her Version ResMed also provides a For Her version of the Quattro FX. The same mask with a few added feminine features like pink headgear and smaller size headgear option. This is also available on our site, and a link is provided on this page.
