I believe there are some concerns here dealing with the use of "masks" during the COVID-19 Pandemic.Features, Evaluation and Treatment Coronavirus (COVID-19)Viable viral efficiency of N95 and P100 respirator filters at constant and cyclic flow.
These NIOSH-approved FFRs and particulate respirators equipped with these cartridges can be anticipated to achieve expected levels of protection (consistent with their assigned protection factor) against airborne viral agents, provided that they are properly selected, fitted, worn, and maintained.
Most masks are NOT used as defined in the guidelines above
Most people "assume" a mask will protect them .....
then WHY do we have first line health care PROFESSIONALS dying of COVID-19 despite wearing PPE ?
Will wearing an N-95 help ? maybe
I use a P-100, please look it up and I still use ALL the protective measures
STAY 6 feet apart
avoid sick folks
WASH WASH hands and face = REPEAT !!!!!!
don't touch your face etc.my P-100 filters 99.7% of ALL aerosols
an N-95 gets about 95% at best and it all depends upon PARTICLE SIZE IN THE AEROSOL DROPLETS
the P-100 protects against particles about 10 times SMALLER than an N-95
People here advising folks that an N-95 IS good protection is not science based IF they have extenuating circumstances in their OWN lives.
Will it help ? maybe
Will it PREVENT ?
I believe the answer is NO.
DO everything else and if you need to use a mask, OK
but please do NOT rely on an N-95 to "PROTECT YOU"
I sincerely pray ALL here stay safe
