The claim: "N95 masks block few, if any" COVID-19 particles due to their size
As many states and communities ease restrictions related to the COVID-19 pandemic, the debate over mask usage has intensified.
Businesses, churches and governments have implemented all manner of policies — some requiring masks, some leaving it up to each person, some even banning masks. And that has spurred many armchair epidemiologists to weigh in, including a Facebook page with nearly 1 million followers.
A June 4 post from
Why don’t you try this? went a step beyond the homemade mask debate to claim that even the N95 masks used by health care workers are pointless in the face of COVID-19.
“COVID 19 virus particle size is 125 nanometers (0.125 microns); the range is 0.06 microns to .14 microns,” the post said. “The N95 mask filters down to 0.3 microns. So, N95 masks block few, if any, virions (virus particles).”
In other words, the post asserts the virus is smaller than the filter on the N95 mask, so the N95 mask doesn’t work. and that was only one medical review there are 100 more online another of them gave specific numbers to how poorly the normal persons mask (non medicaln-95) did and it's even worse. but if you feel better wearing one and it makes you feel safe then do so by all means . so the .05% might be a stretch but so is masks save lives from infections .
