ResMed Mirage FX Nasal CPAP Mask

A proven, lightweight nasal CPAP mask trusted by long-term users. The Mirage FX features a Spring Air dual-wall cushion, flexible butterfly-wing forehead support, SoftEdge headgear, and a four-part design. Standard and Wide sizes.

The ResMed Mirage FX is a proven, lightweight nasal CPAP mask that has built a loyal following among long-term users — and with good reason. At under 70g with headgear, it remains one of the lightest nasal masks available, and its four-part design makes it as simple to clean and reassemble as any mask on the market. The Mirage FX was the direct predecessor to the AirFit N20 series and introduced the Spring Air™ dual-wall cushion and SoftEdge™ headgear technologies that carried through to the current ResMed nasal mask range. Standard and Wide sizes are available on this page. If you need a Small, please see the Mirage FX For Her listing.

Key Features

• Spring Air™ dual-wall cushion with soft-touch frosting — the cushion uses a dual-wall silicone construction: a firm outer wall for support and stability, and a soft inner wall coated with a frosted texture that sits gently against the nose; the inner wall is cut away at the nasal bridge so the softer outer layer makes contact there instead, reducing the pressure and soreness that a harder inner wall would cause in this sensitive area; the in-moulded vent ring at the front of the cushion quietly disperses exhaled air away from the face and bed partner
• Flexible butterfly-wing forehead support — the integrated forehead support uses a flexible winged design that stretches and moves with the user rather than pressing rigidly against the forehead; it distributes pressure gently across a wider area and provides a dynamic range of fit adjustment without adding bulk or hard contact points to the face
• SoftEdge™ headgear — no plastic touches your face — the headgear uses a soft, breathable textile with rounded, seamless edges that eliminate the strap marks and pressure points caused by traditional headgear; the only materials that contact the skin are the silicone cushion and the soft fabric headgear straps
• Squeeze-tab elbow — one-handed release — squeeze the tab to disconnect from the machine without removing the mask; tubing can be attached to the elbow before fitting it to the frame, eliminating the hard push-and-snap of traditional elbow connections; the one-piece construction means no lost parts
• Four-part design — fast to clean and reassemble — the mask consists of just four components: frame, cushion, headgear, and elbow; straightforward to disassemble for daily cleaning and just as quick to reassemble
• Standard fits 9 out of 10 users — the Standard size is designed to accommodate most face shapes; the Wide is available for users with broader nasal features; note that the Small cushion is only available in the For Her range and is not compatible with the Standard or Wide frame

Who Is This For?

The Mirage FX suits existing users who know it works for them and are reordering, and new patients who want a proven, lightweight nasal mask with a straightforward four-part design. It's particularly well suited to users coming from other Mirage-series masks who want to stay within the platform they trust. If you need a Small size, or are a woman looking for a version sized for smaller facial profiles, the ResMed Mirage FX For Her is the appropriate variant. If you're open to a more modern design, the ResMed AirFit N20 is the direct successor to the Mirage FX and uses the same Spring Air cushion heritage in a more refined package.
