Quick answer: The ResMed Quattro FX is a full face CPAP mask (covering the nose and mouth) known for its distinctive minimalist design: soft, flexible frame "arms" curve along the sides of the face instead of a rigid forehead bar, giving an open, unobstructed field of view and a lightweight feel. The dual-wall Spring Air™ cushion self-adjusts to maintain a comfortable seal. It's magnet-free. Includes frame, cushion, and headgear. Available in Small, Medium, and Large. A prescription is required.
About this mask
The Quattro FX was designed to make full face therapy feel less bulky. Instead of a forehead support, flexible spring-frame arms follow the contours of your face, distributing tension gently and leaving your line of sight clear — so the mask feels lighter and less "in your face." The dual-wall Spring Air cushion has a soft membrane that inflates to conform to your face and self-adjust the seal as you move, which helps with comfort and leak control. Soft, wraparound headgear adds stability without bulk. It covers the nose and mouth, making it a good option for mouth breathers or those with nasal congestion.
