A CPAP humidifier is a device that adds moisture to the air you breathe through your CPAP machine. It uses a small tank filled with distilled water and warms the air before it reaches your airway. This helps prevent dryness and irritation in your nose, throat, and mouth that can occur with CPAP therapy. Humidifiers make treatment more comfortable and easier to tolerate, especially for people who experience dry mouth, nasal congestion, or sinus issues. Many modern CPAP machines include built-in humidifiers with adjustable settings to customize moisture levels for your comfort.
