Quattro FX CPAP Masks

The Quattro FX is a full-face CPAP mask designed for people who breathe through both their nose and mouth during sleep — or whose therapy pressure makes a nasal-only mask impractical. Full-face coverage keeps therapy effective for mouth-breathers, patients with nasal congestion, and anyone prescribed higher pressures. This collection brings together the Quattro FX mask and its replacement parts so you can keep an existing setup running rather than replacing the whole system.

What set the Quattro FX apart in its class was the focus on getting bulk off the face. The frame uses flexible arms that shift much of the structure away from the cheeks and out of the line of sight, which matters if you read, watch TV, or wear glasses before falling asleep. The dual-wall cushion is built to seal across a range of pressures without the strap tension that leaves marks in the morning — a common complaint that pushes people to abandon therapy altogether.

A frequent question from buyers: do I need the whole mask, or just a part? If your seal has degraded or you're waking to leaks, the cushion is usually the culprit and the first thing to replace on a regular schedule — most users swap cushions monthly. Headgear stretches over time and is worth replacing when it no longer holds tension. Sizing follows the standard small/medium/large cushion range, and the frame is fitted separately, so confirm both when reordering.

If you're comparing full-face options, the Quattro Air is a lighter successor worth a look, and the Mirage Quattro offers a more traditional full-face design. Prefer something smaller? A nasal mask like the Mirage FX or a nasal pillow system such as the Swift FX suits nose-breathers who want minimal contact. Whichever platform you're on, matching genuine replacement parts to your exact model keeps your prescribed pressure accurate and your seal reliable night after night.
