Breathing protection

The lifespan of a filter depends, among other things, on the concentration of the contamination and breathing intensity. A change in the smell and/or taste or increasing resistance to breathing indicates the filter needs replacing.
Make sure there is always enough oxygen in the ambient air.

AT LEAST 21.9% OXYGEN!

FILTER CLASSIFICATION according to DIN 3181, part 1 and EN-141 (gases), part 2 (fine dust)

0.1 volume % = 1000 ppm (parts per million)

+ Only for unopened factory packaging.
Even if they are unused and well-sealed, opened filters cannot be
kept for over 6 months.
Used filters are not suitable for another gas.
