The Covid masks were championed to filter out viruses and keep Covid out. A wood workers treat…….. you no longer have to purchase safety rated masks!! So I did some turning/sanding with a Covid mask. The results were not good. I was turning Walnut (toxic) and soon started sneezing.
I went to a mirror & saw the places where there were small gaps and bad seals. I also saw walnut dust on my nose. I finished my turning with my safety rated dust mask.
Question: if wood dust gets through, how does it keep out viruses that are a million times or more smaller?
My conclusion is never to use them again as a wood working mask
what do you think?
