"The researchers swabbed the ferrets’ noses and throats every other day to measure the amounts of viral RNA and infectious virus present. By the end of the 13-day experiment, all indirect recipient ferrets in the influenza and SARS-CoV groups had caught the viruses from the donor ferrets, while two of the four SARS-CoV-2 recipients were infected. The four donor and four recipient ferrets infected with SARS-CoV became seriously ill, exhibiting breathing difficulties and less activity than usual, while those infected with SARS-CoV-2 were fully asymptomatic."

So, all the breath escaping out the sides of the mask or the meshing will find its way to others. This is why masks have NEVER been used against airborne viruses as a public health policy. It's pointless. Apart from that it's of course an absolute basic human right to breathe freely.
