I find myself feeling a little sorry for Hedd here; I think all he was implying, and rightly so, was that face masks should not be assumed to offer significant protection from Sars Covid19 on their own.
They are used primarily to prevent the wearer from transmitting virus particles to others, not to prevent the wearer from inhaling particles (though they are partially effective in this role) They do not form a perfect face seal and sneezing or coughing will allow virus to escape from the mask. Virus particles are much smaller than the filter mesh (though small wet particles are trapped) They should be changed regularly and not screwed up in a pocket with loose change, this will reduce mask effectiveness. In short, they are one tool that in the real world “probably” reduces the transmission of Covid19 and should be used in conjunction with social distancing, hand washing and avoiding crowded public places.
“Probably” the most effective action to reduce your chance of contracting Covid is to stay home and not interact with anyone outside your close family bubble. Anything else is a risk…
…But so is venturing out in a 90 year old car with poor brakes, poor lights, poor crash protection and an engine mostly not capable of exceeding 45mph…
You decide what and how much risk you want to take, for yourself and others you might affect by your actions.
