Quick answer: This is the genuine ResMed replacement cushion for the Ultra Mirage Full Face mask (also fits the Mirage Series 2 Full Face) — the soft two-layer silicone cushion that seals against your face. A fresh cushion is the simplest way to fix leaks and restore comfort without a new mask. Choose your size and profile: Small (16604 standard / 16671 shallow), Medium (16605 standard / 16672 shallow), Large (16606 standard / 16673 shallow). This is a vented CPAP cushion. Note: the cushion clip (outer ring) is not included — order separately. No prescription required.
What's included
- 1 × Ultra Mirage Full Face cushion (in your selected size/profile)
Not included: outer-ring cushion clip (sold separately), mask, headgear.
About this part
The cushion is the part of the mask that seals against your nose and mouth — a wear item that degrades with nightly use. This is the genuine two-layer cushion for the Ultra Mirage / Mirage Series 2 full face masks:
- Two-layer design — an outer membrane forms the seal over the face, while the inner layer presses gently against the skin to distribute pressure and reduce marks; seals well without over-tightening the headgear.
- Sizes & profiles — three sizes (S/M/L), each in standard or shallow depth (shallow suits flatter facial profiles). Match to your current cushion.
- Replace regularly — cushions typically last about 1–3 months (longer with good cleaning); if it yellows, hardens, or leaks, replace it.
Compatibility: the ResMed Ultra Mirage Full Face and Mirage Series 2 Full Face masks. This is the vented CPAP cushion (not the non-vented ventilator version).
