ResMed S9 Climate Controlled Heated Humidifier for Superior Comfort

Created to reduce potential nasal congestion and dry mouth, the ResMed S9 H5i Heated Humidifier is available as an attachable add on for the ResMed S9 CPAP device in order to provide bonus comfort and superior performance.

Climate Control

Using the ResMed ClimateLine technology, the S9 H5i Heated Humidifier has a unique climate control system that tracks airflow and the surrounding temperature in the room to adjust the humidity accordingly to provide the best relief. Managing the humidity in the CPAP device, the S9 H5i can effectively eliminate condensation from forming inside the tube, eliminating the threat of rainout in the mask resulting in superior comfort.

Two tubing options available

The ResMed S9 H5i Heated Humidifier has two different tubing options available to allow the owner to choose whichever best fits their needs. The SlimLine tubing is lightweight and flexible which reduces potential mask drag and increases comfort.

Heated tubing in the form of the ClimateLine model is available for customers who prefer heated tubing. With its temperature sensor attached at the mask side, the ClimateLine Heated Tubing manages condensation inside the tube and mask area and helps eliminate excess condensation that can cause discomfort.

Key Features

  • Climate control - Recognizes the surrounding temperature helping to automatically adjust humidity levels.
  • Two different tubing options available - ClimateLine and SlimLine tubing options are compatible with the ResMed S9 H5i Heated Humidifier.
  • Water tub - Sealed water tub that can be hand washed.

Reviewers Tip:

Using distilled water in the water tub will allow you to help lengthen the operating life of the tub. Distilled water will limit the buildup that regular tap water will not reducing the amount of foreign materials entering your humidifier, CPAP device, tube, and eventually mask, resulting in greater results and added health benefits.

Assembling and disassembling the ResMed S9 Humidifier


Is the water tub dishwasher safe?

While we recommend cleaning the water tub regularly, it is not dishwasher safe. Hand cleaning with warm water and a mild detergent, while using distilled water over tap water, will help you preserve life and reduce damage to the tub.

Are there heated tubing options available so I can minimize the moisture in my tube and mask?

Yes, you can find the ClimateLine Tubing for sale for those who prefer to have heated tubing. Like the standard SlimLine tubing, the ClimateLine tubing is lightweight and flexible and has a temperature sensor to manage the condensation levels to help prevent rainout.

Worked very well, I liked that you dont have to have a prescription to get replacement parts. Most places want you to buy the whole unit. So for that it was a great buy and will definitely order again. And it was here on time as promised.

I am getting a message "motor life exceeded, please contact service provider". I'd like to know how to replace this machine (Asked on 05/10/2021)
The message would be about the Cpap vs the humidifier. The S9 is no longer made by Resmed. The replacement is the Airsense S10.
Is item new (Asked on 05/05/2021)
Yes, this is a new item.
