The principle of filter respiratory protection is to remove harmful components from the air before inhalation. For this purpose, special filter materials are used, which must be adapted to the pollutants present. Therefore it is important to know which pollutants are present.
Duration of Use:
The service life of the filters depends on the filter class, the environmental conditions (temperature, humidity, pollutant content…) and the breathing capacity of the user. Gas filters are exhausted when the smell or taste of the gas becomes noticeable: Particle filters and particle-filtering half masks when the breathing resistance increases noticeably.
