About fashion masks
Two or three yuan masks are printed with cute cartoon dolls such as the Pooh bear and sugar rabbit. They are very popular among fashionable women in winter. However, this kind of fashionable mask has no melt blown cloth and no nose wire, so it has no anti-virus effect. Fashion masks are only two layers thick, making it difficult to filter viruses and dust in the air to prevent diseases. Wearing a mask for a long time tends to accumulate viruses and germs. It should be taken off after two hours of use and cleaned and disinfected in time.
