Are the m45 and m50 trading filters adequate for filtering covid-19?

Sir,
The Army Council for Countering Weapons of Mass Destruction (ACCWMD) has a sharepoint set up through the US Army CBRN School website. If you have a valid CAC and nilitary email address, you will be granted access. One of the sharepoint folders is dedicated to COVID-19 FAQ's.
BLUFF:

RFI 1.) Is any Army enterprise currently testing CBRN IPE (JSLIST, M50 filters,
etc.), specifically WRT it's effects against COVID -19?

Answer 1.) The JSLIST and M50 mask protect against COVID. Its just over kill. Its
like a dust or powder agent that you need to keep off your body and out of
your mucus and airways. All the recommendations from the CDC and HHS say a
simple over garment and mask with gloves is enough protection. Its not like
this thing absorbs through material.

There is also a Memo that provides guidance for medical transport of COVID-19 patients from the Office of the US Army Surgeon General. I posted an image of it on this post, but I suggest you go to the CBRN school site and find it for yourself.

Also, as a side note. The M61 filters are considered to be good filters at the time of fielding to the units. (There will be new filters distributed as part of ICE packs during a deployment.) When the indicator on the current filters your organization has, turn blue, then they are only valid for limited training purposes (such as CS gas mitigation during Mask Confidence Exercises).

as well as a retired CA NCO this is the same response I provided Chief Read below:

I would suspect that a training filter that protects against a fine particle aerosol such as CS/CN gas and meets the same criteria for a N95 or KN95 mask would provide the same level of protection you are inquiring about. That said however, you would still need to decon the mask prior to doffing each time its removed as it is not a disposable item. Improper personal sanitizing measures could potentially increase the risk of COVID-19 or other viral spread. A qualified current NBC NCO should be able to provide more precise information.

Positive Pressure SCBA, has more surface area to clean and sanitize as you need to consider the Bottle, carrier, hoses, straps, first and second stage regulators and mask are all part of the PPE envelop depending upon the type and degree of personal protection used.

Most responders would probably wear a Tyvec coverall with hood going into a known hot health environment if available, You are looking at a need for basic respiratory protection from an aerosol droplet versus a finer aromatic hydrocarbon. Thus the current recommendation for N95 masks

Someone, Please get this soldier some info?
