CPAP Water Chamber (Humidifier Chamber)
A CPAP water chamber is a small, built-in container that holds distilled water inside your CPAP machine. As air flows through the machine, it passes over the water and picks up moisture—helping to create a more comfortable breathing experience throughout the night.
Adding humidity can help reduce:
