What do the FFP protection classes mean?
The FFP mask (filtering face piece) is a particle-filtering half mask that can be classified into one of three classes according to the European testing standard EN 149. In the context of the corona pandemic, only masks of classes FFP2 and FFP3 offer a sufficiently high enough level of filtering performance.
| FFP2 Masken | FFP3 Masken | |
| Protection against particles (max. 0,6µm) | min. 94% | min. 99% |
| Maximum total leakage | max. 11% | max. 5% |
| What substances does the mask protect against? | Dust, smoke, mist, solid and liquid particles | Toxic substances, droplet aerosols, carcinogenic substances, radioactive substances, enzymes, viruses, bacteria, fungi and fungal spores |
| Filter | Filter for solid and liquid particles with medium retention capacity | Filters for solid and liquid aerosols with high retention capacity |
| Up to what concentration does the mask protect? | Up to 10 times the maximum workplace concentration | Up to 30 times the maximum workplace concentration |
| Maximum wearing time | 8 hours | 8 hours |
The "D" Symbol
FFP masks with the "D" suffix after the EN 149 standard have passed the so-called dolomite dust test. This tests whether the mask still maintains a good level of breathing resistance even after being subjected to high dust levels. It is therefore a quality indicator showing a mask can still be worn over a long period even at high levels of dust concentration.
The "R"/"NR" Symbol
After the EN 149 standard, many FFP masks also have the abbreviation "R" or "NR". This suffix indicates whether the product is disposable or reusable. R stands for reusable and NR for non reusable - i.e. a disposable product that may not be reused.
