The DeltaWave is designed to provide comfort and breathing ability. As uncomfortable masks may be one of the reasons patients discontinue their therapy, the DeltaWave nasal pillow interface employs fluid dynamics to ensure each breath has adequate airflow to satisfy demand, allowing users to breathe at their normal respiratory rate with no mechanical interruption. 

In addition to supporting breathing rate with no noticeable resistance to exhalation, other features of the DeltaWave include low noise, one simple and loose-fitting head strap, and less or sometimes no need for humidification, according to the company’s website.
