It has been widely understood that Masks can protect someone from inhaling the Covid19 virus and also prevent someone who has the virus from transmitting it, including those who are not manifesting symptoms.
Some people opt to add an additional filter inside their masks as an extra protective layer to mimic the powerful N95 masks used in hospital settings.
According to the Huff Post article, “use of filters helps promote safe breathing and ensures that particles are removed properly.”
Your filter (which you should replace often) is very important. Filters must be sandwiched between two layers of fabric to prevent the inhalation of filter materials.
