What is the role of a CPAP humidifier? Is it necessary to use it?

No. It is not necessary and some people don’t use it at all or only use it during the winter when the air is very dry due to heating. The purpose of the humidifier is to moisten the incoming air so that it doesn’t dry the sinuses. If you breathe solely through your nose, your nasal passages naturally humidify the incoming air.

    1. A humidifier could possibly help. Are you using a Full-face mask? If so, it definitely will, but there could be other causes and solutions to pursue.
