Dual-Wall Spring Air Cushion for Mirage FX Nasal CPAP Mask

The ResMed Mirage FX replacement cushion uses Dual‑Wall Spring Air technology to create a stable seal with light contact. That means fewer interruptions from leaks and a softer feel against your nose during therapy. Made from soft silicone with a supportive frame, it balances comfort and stability so you don’t have to overtighten your headgear to stay sealed. It’s a single replacement cushion—swap it in to refresh your mask and keep therapy on track. *Because great nights start with a great seal.*
