Travel CPAP machines are more portable so you can get a good night's sleep no matter where you are. Travel CPAP's provide the same power with added convenience. Whether you're flying, driving, walking, or cycling, travel CPAPs take up less space on your nightstand and are easy to pack in your luggage. Waterless humidification (such as HumidX) is available on various travel devices, such as the ResMed AirMini, allowing you to save weight and space by leaving distilled water at home.
