What Is The FFP2 Mask
FFP2 mask refers to masks that meet European (CE EN1409: 2001+A1:2009) standards. The standards of European protective mask are divided into three levels: FFP1, FFP2, FFP3. Europe uses DOP oil to dust.
The FFP2 category of masks, both European and American standards, are specified for testing with the American TSI-8130 Automated Filter Testers. The American standard uses the NaCl method for class N, the DOP method for class R, and the DOP method for European standards.
The TSI-8130 instrument uses the NaCl method. The instrument can automatically generate salt particles. The average diameter of the particles is 0.2 μm (aggregated average diameter 0.26 μm, arithmetic average diameter of 0.07 μm). The sample is set to pass through the sample at a certain flow rate, and the instrument automatically prints the flow rate, resistance, and transmittance.
According to the tested particle transmission rate, it is divided into three levels: P1 (FFP1), P2 (FFP2), P3 (FFP3). FFP1 Minimum filtering effect ≥80%，FFP2 Minimum filtering effect ≥94%，FFP3 Minimum filtering effect ≥97%.
There are 3 the most common standards for the face masks USA standard, China standard and European standard, We can compare these standards here here：
| Standard | Class | Filter Efficiency |
| USA Standard (NIOSH 95 42CFR84) | N95 | ≥95% |
|
European Standard (EN149:2001) |
FFP1 | ≥80% |
| FFP2 | ≥94% | |
| FFP3 | ≥99% | |
|
China Standard (GB 2626-2006) |
KN90 | ≥90% |
| KN95 | ≥95% | |
| KN100 | ≥99% |
