- Why does my CPAP nose mask get water in it?
As the air cools, the moisture from the air condenses into droplets inside of the tubing. The tubing can fill with water. The water can flow down the tubing and into your mask. This is condensation of the humidified air and is often known as “rainout.”

Recap. Condensation occurs when the temperature outside of the CPAP mask and tubes is lower than the temperature and humidity within. This can cause "rainout" in which the condensed moisture drips on your face.
