ResMed AirFit N20 CPAP Nasal Mask
£81.99
The ResMed H5i Heated Humidifier is designed for use with compatible ResMed S9 series devices to help improve comfort during CPAP therapy by adding heated humidity. By delivering consistent moisture, it can help reduce dryness and irritation associated with pressurised airflow, supporting a more comfortable therapy experience for many users.
This listing is for the H5i humidifier unit only. Please note that the water chamber is not included and must be purchased separately.

The H5i integrates directly with the ResMed S9 platform and supports heated humidification for improved comfort. It is designed to work with compatible tubing options and climate control accessories (where applicable), allowing therapy to be tailored to individual comfort needs.
