Compatible Water Chamber for AirSense 11 HumidAir Humidifier

This compatible water chamber is designed to fit the AirSense 11 and AirCurve 11 HumidAir heated humidifier, providing a practical alternative to the original chamber. With a 380 ml capacity, it delivers a full night of heated humidification to help prevent dry mouth, nasal irritation and condensation in the tubing. The chamber opens easily for daily emptying and rinsing, with a clearly marked maximum fill line to prevent overfilling. Made from BPA-free plastic with a silicone seal, it fits securely within the S11 series humidifier housing. Distilled water is strongly recommended to prevent mineral deposits and bacterial growth.
