Cleaning the exhalation valve

For reasons of hygiene, clean the exhalation valve once a week. To do so, proceed as
follows:

1.  Clean the exhalation valve with mild soapy water. Do not use any other agents!
2.  Rinse the exhalation valve thoroughly with clear water.
3.  Let the exhalation valve air-dry completely.

When using other exhalation valves, the manufacturer’s instructions must be observed.
Exhalation valves not designed for reuse must be disposed of properly.
