"The salt coating on the fiber surface dissolves upon exposure to virus aerosols and recrystallizes during drying, destroying the pathogens. When tested with tightly sealed sides, salt-coated filters showed remarkably higher filtration efficiency than conventional mask filtration layer, and 100% survival rate was observed in mice infected with virus penetrated through salt-coated filters."

wow toto znie az prilis dobre/jednoducho, namocit do slanej vody a nechat vysusit. znamenalo by to aj ze kuchynske utierky by fungovali este lepsie kvoli svojej hrubke a savosti.

vie sa k tomu niekto fundovane vyjadrit?
