The exhalation “valve” on the SleepWeaver is a series of very small holes that gently and quietly exhaust the exhaled air from the mask. These holes provide quiet operation without creating a jet of air that make a lot of noise or can blow on the patient’s bed partner. The leak rate provided by the exhalation holes is comparable to competitive PAP masks.

As long as the mask is properly maintained and washed the exhalation valve will provide consistent exhaust performance.
