ResMed AirSense 11 HumidAir CPAP Water Tub

The ResMed HumidAir 11 is a heated humidifier tub designed for use with ResMed’s AirSense 11 series machines. It adds moisture and warmth to the airflow, helping prevent dryness, nasal irritation, and congestion during CPAP therapy.

Comfortable Humidification

The HumidAir 11 delivers warm, moist air that soothes your airway and reduces the common side effects of dry mouth, throat irritation, and nasal discomfort. Its integration with the AirSense 11’s Climate Control settings allows for automatic adjustment of temperature and humidity to maintain comfort.

Compatible & Integrated

Designed specifically for the AirSense 11 lineup, the HumidAir 11 is recognised automatically by the machine and works seamlessly with the device’s controls. You can choose between a standard water tub for single patient use, or this cleanable version suited for multi-user or clinical environments.

Prevents Condensation (“Rainout”)

When paired with ResMed’s ClimateLineAir 11 heated tubing, HumidAir 11 helps maintain stable air temperature and minimises condensation in the hose, ensuring your therapy remains comfortable and dry throughout the night.
