Specifications of FFP2 protective masks

Regardless of whether it is a European protective mask or an American protective mask, it is designated to use the US TSI-8130 Automated Filter Testers instrument for testing. The US standard N class uses the NaCl method, the R class uses the DOP method, and the European standard uses the DOP method. European testing uses DOP oil to generate dust. The particle diameter of DOP oil is 0.33μm in aggregate average particle size and 0.20μm in count average diameter. The filtration efficiency is required to be no less than 94%. On the one hand, the filtration effect is related to the particle size of the particles, and in addition, it is also affected by whether the particles contain oil.Ear Belt Type Fashion Color FFP2 Mask passed the test of ffp2.

The breath test standard of the FFP2 protective mask is also very harsh. The detection flow rate used in the inhalation resistance test is 95L/min, and the detection flow rate used in the expiration resistance test is 160L/min.

Strict filtration efficiency and breathing resistance test standards make (Ear Belt Type Fashion Color FFP2 Mask) protective masks have high requirements for filter materials. The FFP2 protective mask is made of high-end nano new materials, which not only has a lot of comfort, but also has better adhesion. The filtration efficiency test exceeds 96%. It protects the health of personnel by filtering and blocking the infiltration of harmful substances such as dust particles, bacteria, viruses and oily particles in the air. The surface morphology of the new nano material is a spider web-like microporous structure, which is a flexible and elastic microporous material with high porosity, uniform pore size distribution, and air permeability and impermeability. At the same time, it has a breathing function to ensure the comfort of wearing. This material is a high-performance material with high temperature resistance, corrosion resistance, high toughness and strength, and very good biocompatibility. Different from the meltblown cloth which uses the principle of electrostatic adsorption to filter bacteria and viruses, the fiber and pore size of the nano material are all at the nanometer level, which can directly block bacteria, viruses and dust through the function of a physical barrier.
