Keep your humidity consistent and comfortable with the original ResMed HumidAir water chamber for AirSense 10 (CPAP/Elite/AutoSet), AirCurve 10, and AirStart 10 devices.
Not compatible with S9 (H5i) or AirSense 11. This model is specifically for Air10-series devices with the built‑in HumidAir humidifier.
Why replace? Even with good cleaning, hard‑water minerals and heat gradually cloud, pit, or warp the tub. A fresh chamber helps maintain stable humidity and reduces leaks, odors, and scale buildup.
Capacity: up to ~380 mL (filled to the max line).
