FFP2 mask

FFP2 masks talk about masks that meet the actual European (CEEN149: 2001) requirements. The European standards to get protective masks are separated into three levels: FFP1, FFP2, in addition to FFP3. The difference in the American standard is which its detection flow quote adopts 95L/min, and DOP oil is used to generate dust. The role is usually to absorb harmful aerosols, as well as dust, smoke, mist, toxic gases and poisonous vapors, with the filter material, and prevent them from being inhaled by people.
Different FFP2 kinds of masks use different sieve materials. On the just one hand, the filtering effect is related to the particle size belonging to the particles, and it is also affected by whether the particles contain oil. FFP2 masks are usually classified according to filtration efficiency and whether they may be suitable for filtering slimy particles. Oil-free particles just like dust, water-based mist, color mist, oil-free fumes (welding fumes), microorganisms, and many others. Although the filter materials of "non-oily particulate matter" are definitely common, they are not worthy of oily particulate matter, like oil mist, oil fume, try to sell fume, coke oven fume, for example. The filter material made for oily particles can even be used for non-oily particles.
The outer layer regarding FFP2 masks tends to accumulate lots of dust, bacteria and other dirt while in the outside air, while the inner layer blocks exhaled bacterias and saliva. Therefore, each sides cannot be utilized alternately, otherwise the dirt to the outer layer will always be directly It becomes a cause infection by inhaling our body when it is towards the face. When you usually are not wearing the mask, you ought to fold it into some sort of clean envelope, fold along side it close to your nostril and mouth, and don't just stuff it in your pocket or hang the item around your neck.
FFP2 masks are similar to N95 and KN95 masks and can not be cleaned. Because it will get wet, the mask will certainly release static electricity, and it is definately able to absorb dust using a diameter less than 5um.
High-temperature steam disinfection resembles cleaning. Water vapor will even cause static discharge, that can cause the mask that will fail.
