The filter performance is good, and the barrier efficiency is higher
the diameter of ordinary non-woven fiber used in the traditional mask is more than 1000nm, while the diameter of polytetrafluoroethylene mask is between 100nm and 200nm, which can effectively block PM2.5 in the air, as well as some viruses, bacteria and particles invisible to the naked eye. For the fineparticles with a diameter of 75 nm, the filtration performance is over 95%+, which meets the standards of disposable 3ply face mask, N95 and kn95.It is easier and more breathable when wearing
The traditional mask materials have poor air permeability, and will feel damp and sultry when wearing for a long time, which is not conducive to physical and mental health. meltblown nonwoven has a three-dimensional structure, which has the air permeability unmatched by other protective materials, and it will not feel damp when wearing for a long time.
