The humidifier's water chamber works hard. It fills up every night, empties every morning, and is frequently washed, so it eventually shows deposits or marks that won't go away. This water chamber for the DreamStation 2 replaces only the container, without the lid, when the one you have is still in good condition.

• Slides into the DreamStation 2 just like the original water chamber, with no adjustments or additional parts
• New container, free of embedded deposits at the bottom, easier to rinse every morning

You reuse the existing lid and resume your evening routine with a clean container.
