Noise is an important factor to consider when shopping for a sleep apnea machine, but it's not the only feature that matters. Other important features include machine size, data reporting capabilities, therapy modes, and comfort settings. You should also consider whether or not the machine has a heated humidifier. A CPAP humidifier can significantly increase comfort by preventing dry mouth and nose. Learn more about what questions to ask and why in our 2024 CPAP Machine Buying Guide.
