In order to avoid the risk of reduced efficiency of the mask during storage and use, electrostatic adsorption cannot be used to capture particles, and particles can only be intercepted through pure physical interception. If you want to rely on pure physical interception to achieve high-efficiency filtration, the fiber The size must reach the nanometer level, and the ffp2 mask filter material can meet the above requirements.
The European Union’s respiratory test standards for FFP2 protective masks are also very strict. The detection flow rate used in the inspiratory resistance test is 95L/min, and the detection flow rate used in the expiratory resistance test is 160L/min (the domestic inspiratory and expiratory resistance test uses The detection flow rate is 85L/min).
Such stringent filtration efficiency and breathing resistance standards have caused many manufacturers to back down.
The filtration efficiency of ffp2 mask filter material for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
The ffp2 mask filter materials produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe membrane; using American Imported production and testing instruments are used to test the quality of PTFE film, and have also passed international SGS testing and certification, as well as ISI testing and certification.
