protection from poisonous and deleterious kinds of dust, smoke, and aerosols
when working with oncogenic or radioactive substances or pathogens such as viruses, bacteria and fungal spores FFP3-class respirator masks are recommended
total leakage may amount to a maximum of 5%
OEL transgression to the thirtyfold value
Protection class FFP3 respirator masks offer maximum protection from breathing air pollution. The total leakage may amount to a maximum of 5% and they must filter 99% of all particles measuring up to 0.6 μm. This kind of mask also filters poisonous, oncogenic and radioactive particles. Protection class FFP3 masks are used in working environments transgressing the OEL by the thirtyfold industry-specific values. They are often used in the chemistry industry.
