Description

The ResMed AirSense 11 CPAP End Cap replaces the humidifier water chamber on your AirSense 11 or AirCurve 11, giving you a smaller, lighter machine profile when you don't need the humidifier. It's the straightforward solution for travelers or anyone who wants a cleaner, lower-maintenance CPAP setup without swapping to a different device.

The end cap clicks into place in seconds and automatically disables the humidifier function — no settings adjustment needed. With the water chamber removed, there's nothing to fill, rinse, or dry, which simplifies your nightly routine considerably. This is the ResMed OEM replacement (Product Code: 39226), designed specifically for the AirSense 11 and AirCurve 11 series.
