Replacement Water Chamber for Respironics DreamStation Humidifier

Designed to work with any Respironics DreamStation CPAP /APAP /BiPAP /BiPAP ST /BiPAP AVAPS humidifier, Philips has you covered with this replacement chamber. This water chamber is designed to be hand-washed daily after every use. Designed to improve the humidity from your DreamStation Machine Humidifiers, this chamber will hold up to 325 mL which is the maximum fill line. Humidification can help relieve potential congestion that can occur during CPAP use. The amount of water used will be different depending on the user and the machine and should be changed daily with distilled water for best results.

Key Features

  • High Capacity - Holds 325mL (11oz) of water to help improve humidity
  • Compatibility - Will work with DremaStation devices with the exception of DreamStation Go
  • Easy maintenance - Can be opened and cleaned to improve hygiene

Reviewers Tip:

 This water chamber can be washed in the Dishwasher on the top rack once a week however it is recommended to handwash it daily with mild detergent. Once washed, it is best to allow it to dry out completely away from direct sunlight or a heat source prior to re-using for the night. For optimal use, the chamber should be replaced every 6 months or if it appears damaged or worn. 

No Prescription is Required.


Can I use normal tap water in my Respironics water chamber?

While you can use tap water, we recommend using distilled water for all water chambers in order to provide the best results with your CPAP device. Distilled water will also extend the life of the Respironics water chamber.

How often should I be cleaning my water chamber and with what materials?

We recommend cleaning your Respironics water chamber daily. Warm water and a mild detergent usually do the trick.

Is a humidifier really necessary for my CPAP device?

Your CPAP machine will work without humidification and therefore you do not need a humidifier and water chamber, however, many CPAP users find that they are congested in the morning or experience discomfort after using their CPAP machine. Humidification will add moisture to your tube and help relieve any potential discomforts from congestion.

the water level in the humidifier chamber usually goes during the night so I have to refill each night before bed. How come the level now stays the same every night?
The level will change as the environment changes outside is the main reason or if you humidifier setting is different
