ClimateLine heated tubing is designed to improve your CPAP therapy experience by delivering air at consistent, comfortable temperature and humidity levels. It is a key component of ResMed’s Climate Control humidification solution for S9™ devices.  

For use with devices in the S9 series and only, when the H5i humidifier is attached. If you are using your S9 device without the H5i humidifier, please use the SlimLine or Standard air tubing.

Products available on this store are intended for sale in the United Kingdom only. 


The ClimateLine heated tube is a key component of ResMed’s Climate Control humidification solution. Smart technology delivers air at your desired temperature and comfortable humidity levels. This can prevent water from accumulating in the tube, so you can enjoy the simple pleasure of a restful night.

  • Comfortable: smaller, slimmer and sleeker than a standard mask tube, ClimateLine tubing offers greater flexibility and less mask drag for a more comfortable night’s sleep. 
  • Adjustable temperature: thanks to a temperature sensor built into the tube, the Climate Control algorithm is able to deliver consistent, comfortable temperature at the mask. 
  • Adjustable humidity: the Climate Control algorithm automatically adjusts to changes in ambient conditions. It protects you from rainout by maintaining a target humidity level, even if the temperature drops overnight. 
  • A complete solution: the ClimateLine tube is part of ResMed's Climate Control solution based on S9 devices and the H5i™ heated humidifier. 

Please refer to the user guide for relevant information related to any warnings and precautions to be considered before and during use of the product. Ask your doctor about using this medical device to treat your obstructive sleep apnoea.
