With regard to chiffon and silk, researchers noted that they have "the combined effect of mechanical electrostatic filtration and. »
It is interesting to note that even if a homemade mask composed of cotton and silk can be effective as a N95 mask, if theFinal result does not match correctlyAnd reveals the gaps of the air around the face, then the efficiency of the mask goes down.
