P100 masks carry a virus rating backed by independent testing. These are the same grade filters our military uses for its biological.warfare masks. Are you.going to say with a straight face that the military.doesn’t know how to.protect our.troops from bioagents. A true P100 mask has a silicon seal and is air.tight around the nose and mouth I own five.different versions ranging from full NBC qualified 40mms NATO threaded gas masks to half masks with replaceable P100 to single use P100 with silicon edge seals that you heat up and mold to your face. At least know what you are talking about. There are masks and more importantly respirators that can and do filters down to 0.01 micron they will.stop any airborne respiratory virus, Ebola or H5N1 or Hanta Virus. They are not cheap good ones are $500 or more each custom.fitted general grade are $80 with $30 filter pairs all will make someone a walking immune in any bioagent live environment. For really nasty bugs like Ebola you.need skin protection as well as in full body suits they are available for $3000 from any reputable prepper shop. Cloth masks are worthless , but virus rated respirators are the real.deal.
Understand
Now the true question at hand
In a cost/benefit analysis, is the cost and discipline necessary to wear such a mask (Retired Military) valid for a virus with a 99.9% survival rate?
