Type IIR
Type IIR medical masks provide the same bacterial filtration performance as Type II masks, but also have splash protection against contaminated fluids.

What does type IIR mask mean?
The type IIR medical face mask has a high splash resistance. According to EN 14683, it must withstand a splash with a pressure of ≥16.0 kPa. Thus, it reliably protects the wearer of the mask from blood splashes or other liquids.
The bacterial filtration efficiency must be ≥ 98%, the same as for the type II mask.
The breathing resistance of the type IIR mask may be higher than that of the type II mask. This is due to the higher splash resistance of the type IIR mask.
Performance requirements
Test | Typ I | Typ II | Typ IIR |
Bacterial filtration efficiency (BFE), (%) | ≥ 95 | ≥ 98 | ≥ 98 |
Pressure differential (Pa/cm2) | < 40 | < 40 | < 60 |
Splash resistor pressure | not applicable | not applicable | ≥ 16,0 |
