Using distilled water in a CPAP machine serves multiple benefits, especially for travelers. It not only guarantees cleanliness but also prolongs the life of your equipment by preventing mineral buildup.

This means that while purified or spring waters are safe for drinking, they may still contain minerals that could damage your CPAP machine over time, leading to symptoms like runny nose and sore throat if used regularly in place of distilled water.

Careful use of distilled water ensures the seamless functioning of the CPAP machine, offering quality sleep irrespective of where you’re traveling.
