What is Rainout in CPAP Masks? 

Rainout in CPAP masks occurs when the humidity reaches the unheated tube, and the temperature difference creates condensation. Due to this, small droplets of water occur around your face, and you get up from it. 

The heating air cooling inside the CPAP mask generally causes this rainout. If there are warmer humidifiers and cooler bedrooms, there are more chances of rainout.

How to Prevent Rainout from CPAP Hose and Masks? 

  • Use CPAP Tubing: You can use heated tubes that help to manage the humidification in real-time based on the ambient temperature levels of the bedroom. This heated tubing helps to reduce the rainout from the CPAP masks as it keeps the air consistent while traveling to the humidifier to your mask. 
  • Cover the CPAP mask: You can use some tube covers that are specially designed for this purpose. These masks help to insulate the hose and block the ambient temperature of your bedroom from causing rainouts in the CPAP mask. In addition to this, you can also run your hose underneath your bed, which will provide additional warmth to the tube, and thus, it will become effective. 
  • Adjust the Room Temperature: The rainout occurs when there are changes between the temperatures of the tube and the room. If you keep your room extra cool during the night, there is a high chance that your mask will face the rainout. So, as per the warmth required by the masks, you should adjust your room temperature. 
  • Adjust Humidifier Settings: There are options for setting the warmth and coldness of the masks, and therefore, to protect the masks from rainout, you can adjust the settings and set them as per the warmth and temperature of the room. However, before changing the temperature of the humidifier, you must consult professionals about whether it will suit you.
