Philips DreamStation Water Chamber

This is the water tank that sits inside the heated humidifier of the original Philips DreamStation. It holds the water the humidifier warms overnight, which adds moisture to your therapy air and can make long nights on CPAP easier on your nose and throat.

It fits the humidifier module that slides onto the back of first-generation DreamStation CPAP, Auto CPAP, and BiPAP machines. You get the tank by itself, Philips part 1122520, since the lid and lid seal stay with your humidifier.

Key features:

• Holds 325 mL: Filled to the max line, one tank is meant to see you through a typical night's sleep.
• Second level guide: Keep the water below the bottom of the rear tube as well as the max line, so the tank won't spill going back in.
• Dishwasher safe: Philips rates it dishwasher safe on the top shelf, so weekly upkeep takes no extra effort from you.
• Simple to seat: Lower it into the humidifier, close the lid until it snaps, and your therapy is ready to start.
• Distilled water only: Room-temperature distilled water with nothing added is what Philips specifies, and you fill it with the tank out of the humidifier.
• Travel ready: Empty it, let it dry, and put it back in the humidifier before packing the pair in your carry-on.

It suits anyone still sleeping with a first-generation DreamStation and its heated humidifier who wants a fresh tank. If your machine is a DreamStation 2, or a System One, it uses a different tank, so check the model name on the device before ordering.

Note: The DreamStation 2 and System One 60 Series tanks look similar but are separate Philips parts, and this tank is made for the original DreamStation humidifier only.
