Heated CPAP hoses typically contain embedded metal coils that use electricity to generate heat, similar to a heated blanket. This specialized type of CPAP hose is designed to be paired with a CPAP humidifier. Humidifiers increase the amount of moisture in the CPAP air to prevent uncomfortable symptoms like dry mouth, thirst, dry nose, and nosebleeds. CPAP humidifiers can make your CPAP therapy more comfortable, but sometimes excess moisture leads to condensation that pools inside of your CPAP tubing. By adding heat to your CPAP system, a heated hose allows the pressurized air to hold more moisture. This helps prevent condensation from forming and water from pooling in your CPAP hose.
