So the folks on CBS are telling people that “Normal” masks used for Covid are not gonna work for the particulates causing bad “air quality” in the eas coast states coming from the Canadian wildfires….That AT A MINIMUM one needs an N-95 or better mask for it to be effective. And to be sure you get enough air through the mask when exerting yourself…
Huh. And all that Canadian smoke is so much larger than those Covid (and other) virus particles…..
Whoda thunk that all those Covid masks were useless? Someone should have said something earlier….
