Product Features

Compatible with Series 10 Machines

The ResMed HumidAir™ Humidifier Replacement Water Chamber is specifically designed for use with ResMed AirSense 10, AirCurve 10, and AirStart 10 machines. The replacement water chamber ensures that your device continues to deliver optimal humidification and the comfort you expect.

Designed to Last

The water chamber has a durable design with a metal base plate for long-lasting performance. The circular metal base plate enhances the stability and durability of the humidification system. Consider a protector mat to protect your nightstand from spills.

Essential for Device Operation

A water chamber or a replacement side cover must always be installed in the AirSense, AirStart, or AirCurve device for it to work properly. The device can operate with an empty water chamber when set to Airplane Mode, but the chamber must still be in place.

Water Chamber Installation

The ResMed Standard Water Chamber is crucial for optimal comfort during CPAP therapy for your AirSense, AirStart, or AirCurve device.

  • Always install a water chamber or a replacement side cover for proper function of the CPAP machine.
  • If humidification is not desired, the device can be operated in Airplane Mode with an empty water chamber.

Cleaning and Care Your Water Chamber

The ResMed Standard Water Chamber is designed for straightforward maintenance.

  • Weekly Cleaning: Wash with warm water and mild detergent to remove dust or debris.
  • Drying: After washing, allow the chamber to air dry completely away from direct sunlight and heat sources to prevent mold or bacteria growth.
  • Replacement: Replace the water chamber every 3-6 months for optimal hygiene and performance.

Water Chamber Wide Compatibility

The ResMed Standard Water Chamber is compatible with a range of ResMed devices, enhancing your therapy experience. Compatible models include: AirSense 10, AirSense 10 Elite, AirSense 10 AutoSet, AirSense 10 AutoSet for Her, AirStart 10, AirCurve 10 S, AirCurve 10 ST, AirCurve 10 VAuto, and AirCurve 10 ASV.

ClimateLineAir Compatibility

When used with ClimateLineAir heated tubing (sold separately), the Standard Water Chamber integrates with the HumidAir humidifier to provide temperature-controlled, humidified air. This system, known as Climate Control, helps reduce rainout by maintaining the air temperature and humidity, thereby minimizing condensation in the tubing. This ensures less dryness and congestion while enhancing overall sleep comfort with warm, humidified air.

Important Tips

  • Always use the water chamber with your AirSense or AirCurve 10 device for full humidification benefits—this prevents dryness and enhances sleep comfort.
  • Fill the chamber only with distilled water to avoid mineral buildup that can damage your machine.
  • Never overfill the chamber—use the fill line as a guide to prevent water from leaking into the machine.
  • If you're not using humidification, operate your device in Airplane Mode with an empty chamber or insert a replacement side cover.
  • Clean the chamber weekly with warm water and a mild CPAP soap to remove dust and residue.
  • Let the chamber air dry fully after washing—avoid placing it in direct sunlight or near a heat source to prevent warping or mold.
  • Inspect the chamber regularly for cracks or discoloration, which are signs it's time for a replacement.
  • Replace your water chamber every 3 to 6 months to ensure hygienic and efficient therapy.
  • For a deeper clean, use a CPAP cleaning machine that sanitizes the chamber along with your tubing and mask.
  • Pair the water chamber with a ClimateLineAir heated tube to enjoy Climate Control—warm, humidified air that reduces rainout and congestion.
  • Add a CPAP tubing cover to improve insulation and further reduce condensation in the tube.
  • If you notice dryness despite humidification, double-check the chamber’s water level and verify that the heated tubing is properly connected.
  • Cleaning your entire setup regularly—including tubing, mask, and water chamber—is easier with a complete CPAP cleaning kit.
  • Always insert the water chamber fully into the device to ensure a proper seal and avoid leaks.
  • For side sleepers or anyone sensitive to airflow changes, combine your setup with a CPAP pillow for better positioning.
  • Wipe down the outer surface of the chamber with CPAP wipes to keep the housing area clean and dust-free.
  • Use the part finder if you're unsure about compatibility or need a replacement chamber.
  • Keep a spare water chamber on hand in case of damage or travel needs, so your therapy never gets interrupted.
  • Compatible with a wide range of ResMed models, including AirSense 10, AirCurve 10, and AirStart 10—always verify compatibility through the part finder before purchasing.

Why do CPAP machines have humidifiers?

CPAP humidifiers add moisture to prevent dry mouth, throat irritation, and nasal congestion caused by pressurized air.

Are all CPAP humidifiers the same?

No, there are two types: - Integrated humidifiers (built into the CPAP machine) - Standalone humidifiers (separate units that connect to the CPAP)

Do I have to use a CPAP humidifier?

No, but it helps reduce dryness and discomfort. If you experience dryness, adding a humidifier can improve comfort.

What type of water should I use in my CPAP humidifier?

Use distilled water to prevent mineral buildup and bacteria growth. Avoid tap or bottled water.

How often should I clean my CPAP humidifier?

Daily: Empty and rinse with warm water. Weekly: Wash with mild soap, rinse well, and let it air dry.

Why is there water in my CPAP mask or hose?

This is rainout, caused by humidified air cooling in the hose. Using heated tubing or a hose cover can help.

Can I travel with a CPAP humidifier?

Yes, but some travelers prefer to turn off the humidifier to reduce bulk. If flying, empty the water chamber before packing.

When should I replace my CPAP humidifier chamber?

Every 6 months, or sooner if you notice discoloration, cracking, or buildup that doesn’t clean off.
