ResMed H5i Heated Humidifier

The ResMed H5i heated humidifier delivers relief from dryness and nasal congestion by integrating seamlessly with the ResMed S9 CPAP. It requires no separate power supply — your existing S9 device will automatically detect the H5i when connected.

The H5i includes intelligence that helps deliver consistent humidity and minimize rain-out during standard humidification. It can be used with the standard SlimLine tubing or the recommended ClimateLine heated tube. Using ClimateLine heated tubing further optimizes relative humidity and reduces rain-out.

Tip: For best results use the H5i with ClimateLine heated tubing to optimize humidity control and reduce condensation in the tube.

Supported Modes (H5i)

• Patient: Traditional humidifier mode — warms until it reaches the selected humidity setting (or 80%).
• Auto: Recommended when using ClimateLine heated tubing. Auto mode defaults to a Climate Control setting of 80°F (approx.) and can be adjusted up or down as necessary to maintain comfort and prevent rain-out.
• Off: The H5i can be set from OFF to 6 (via the S9 HOME screen). A setting of 3 is average; higher numbers produce more humidity.
