For maximum concentrations of contaminants and other limitations see the instructions for use of
the gas filters.
3.2
Particle filters
Particle filters are classified according to EN 143:2000 in 3 classes: P1, P2, P3 in ascending order
of the filter performance.
The additional marking with “R” [reusable] means, additional tests according to
EN 143:2000/A1:2006 were done to verify, that the particle filter or the particle part of combination
filters is qualified for usage after an exposure against aerosols and may be used for more than
one shift. Filter marked with "NR" [not reusable] must only be used for a single shift only against
particles.
3.3
Service time
The service time of respiratory protective filters depends on the conditions of use. The end of
service time of gas filters or the gas filter part of combined filters, most of the time can be detected
by odour on the clean air side. The filter must then be replaced.
The end of service time of particle filters or the particle filter part of combined filters, most of the
time can be noticed by an increase in breathing resistance. The filter must then be replaced.
Particle filters that have been used against radio active substances, micro organisms or bio-
chemically active substances must only be used once!
In any case applicable National Regulations must be observed, especially to determine
maximum allowable concentrations of toxic gases when using filters in conjunction with
half or full face masks.
Always the lowest concentration applies.
In any case applicable National Regulations must be observed, especially to determine

Always the lowest concentration applies.
Attention!
When using particle filters against radioactive substances, micro organisms
[virus, bacteria, fungi and spores thereof] and bio chemically active substances
[enzymes, hormones], only P3 filters with full face masks must be used.
The filters must be used only once.
The higher particle filter class includes the protective range [retention capability] of the
lower particle filter class when using in conjunction with the same facepiece. Pre-filters
may be used to prevent premature clogging through large particles [e.g. when paint
spraying], therefore a more frequent re-placement of the Pre-filters may be necessary,
if the breathing resistance increases.
