Filter type Colour Application
A brown Vapours from organic compounds with a boiling point higher than 65 °C
B grey Inorganic gases and vapours, e.g. chlorine, hydrogen sulphide, hydrogen cyanide
E yellow Sulphur dioxide, hydrogen chloride, acid gases
K green Ammonia and derivatives of ammonia
P white Against particles of hazardous materials with a negligible vapour pressure
For the gas filters A, B, E and K, the filter class to be used depends on the possible maximum concentration of the
hazardous gas and the required service time.
The classification, which is determined by the minimum breakthrough time of gas filters or gas filter part of a
combination filter in laboratory tests under specified conditions, does not give any indication of the possible service
time in practical use. Depending on the conditions of use, possible service times can deviate positively or negatively
in both directions from the breakthrough times determined according to the present document. The classification of
a filter does not reflect actual usage performance in the workplace and does not relate to any established workplace
exposure limits.

class 1

class 3
Important notice: 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 Germany, the following applies: When using filters with half masks, the maximum 30-fold limit value applies as
the limit of use, and in conjunction with full-face masks, the maximum 400-fold limit value applies as the limit of use.
In any case, the limit values for filter classes 1 to 3 must not be exceeded.
3.2 Particle Filters
Particle filters are classified according to EN 143:2000 or EN 143:2021, GOST 12.4.246-2016, DSTU EN 143:2002,
in 3 classes: P1, P2, P3 in ascending order of the filter performance.
Important notice: 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.
WARNING!
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. In Germany, the restrictions of BGR 190 apply. The filters must be used only once.
Failure to follow this warning can result in serious personal injury or death.
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
replacement of the Pre-filters may be necessary, if the breathing resistance increases.
The additional marking with "R" (reusable) means, additional tests according to EN 143:2000 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.
