These masks have been approved by INSPEC, UK and they meet the European standard En 149:2001 for FFP2 masks. This means that the respirators protect you against solid particles and water-based non-volatile liquid particles. Moreover also they have passed the dolomite.
The nominal protection factor is 12 and the protection assigned is 10. Respirators can be used in concentrations not exceeding 12 times the occupational exposure limits.
The Segre P2 mask has been proved in the following aspects: filtration, flammability, resistance to breathing, internal filter, and a general assessment test in accordance with the European standard that included the exposure of 120mg test.
The valve reduces the temperature, the condensation and the humidity inside the masks. It also facilitates the exhalation of the worker and therefore the mask offers less resistance to breathe.
