How long does a filter last?

The service life of a respiratory filter depends on its size and on the conditions of use. Factors affecting service life:

• concentration of the contaminants

• combination of the contaminants

• air humidity

• temperature

• duration of use

• breathing rate of the user

Since the service life is influenced by many factors, it is not possible to give an estimated service life.

The end of service life is generally recognizable by:

• gas filters by a noticeable taste or smell of the contaminant

• particle filters by an increased breathing resistance

• combination filters a noticeable taste or smell and/or an increased breathing resistance
