ResMed Mirage Activa LT Cushion with Clip (ActiveCell)

Description

Quick answer: This is the genuine ResMed ActiveCell nasal cushion with clip for the Mirage Activa LT (and Mirage SoftGel) nasal masks — the replacement cushion that restores a fresh, comfortable seal. Its ActiveCell dual-wall design uses a bubble-like inflatable membrane that expands and contracts with your movement and pressure changes, giving a gentle, stable seal without over-tightening the headgear — ideal for active sleepers. Each pack includes one cushion and one clip. Choose your size: **Small (60198), Medium (60177), Large (60178), Large Wide (60179)**.

What’s included

• 1 × ActiveCell nasal cushion (in your selected size)
• 1 × cushion clip

Mask frame, headgear, and elbow not included.

About this part

The cushion is the part of the mask that seals against your nose — and it’s a wear item, so a fresh cushion is the simplest way to fix leaks and restore comfort without replacing the whole mask.

This is the ActiveCell cushion, ResMed’s design for the Activa LT and SoftGel:

• ActiveCell dual-wall cushion — a bubble-like membrane surrounds the cushion and inflates/deflates to varying pressures, creating a gentle sealing force that adapts as you move.
• Great for active sleepers — it decouples mask movement from the face, so the seal holds through position changes, reducing leaks and wake-ups.
• Gentle seal, less tightening — the self-adjusting membrane means you don’t need heavy headgear tension.
• Includes the clip — for fast, easy installation onto the frame.
• Replace regularly — cushions wear with nightly use (commonly replaced about twice a month) as facial oils and pressure degrade the silicone.

Sizing — important (Small uses a different frame)

Match the cushion to your frame:

• Small = 60198 · Medium = 60177 · Large = 60178 · Large Wide = 60179
• ⚠️ The Small (60198) uses a smaller frame — the Small cushion/clip fits only the Small Activa LT / SoftGel frame.
• Medium, Large, and Large Wide all use the same “standard” frame, so those three cushions are interchangeable on a standard frame — but not with the Small.

If you’re unsure of your size, check your current cushion’s part number or contact us.
