Medical masks are divided into ordinary medical masks, medical surgical masks and medical protective masks.
Ordinary medical masks are not required to have a blocking effect on blood and have no tightness requirements, so they are only used in ordinary medical environments.
Medical surgical masks can block blood and body fluids from passing through the mask and contaminating the wearer. At the same time, the filtration efficiency for bacteria is more than 95%, but the filtration efficiency for particles is limited, and most of them are rectangular in design.
The ffp2 mask filter material is prepared using a unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.
When used for gas filtration, it can achieve 100% interception of various phages, bacteria and particles above 0.02um.
