Information

The detection of FFP2 masks, whether it is the European standard or the American standard, is specified with instruments for testing. The American standard N type uses the NaCl method, the R type uses the DOP method, and the European standard uses the DOP method.

FFP2 in china The NaCl method is used to detect FFP2: the instrument can automatically generate salt particles with an average diameter of 0.2μm (average aggregate diameter of 0.26μm, arithmetic average diameter of 0.07μm). After setting a certain flow rate to pass through the sample, the instrument automatically prints out the flow rate, resistance, transmittance.
The DOP method was used to detect FFP2, and DOP oil was used to generate dust. The diameter of DOP oil particles was 0.33 μm in aggregate average particle diameter and 0.20 μm in average counting diameter.
Daily masks: The FFP2 manufacturers tell you that the so-called daily masks refer to the kind of textile masks that can completely cover the mouth and nose, and even a scarf or head scarf can play the same role.
The FFP2 manufacturers tell you that when the user exhales, this kind of mask can slow down the speed of the airflow, which can greatly reduce the risk of infection to the surrounding people. But everyday masks don't protect the wearer from infection because they don't stop the virus from entering the body through breathing.
However, The FFP2 manufacturers tell you that if everyone wears masks and maintains proper social distancing, everyday masks can also slow the spread of the virus.
Through the above introduction and analysis of the Instruments used to detect FFP2, hope it helps you.
