I tested out a mask changing the cats’ litterbox. It didnt even stop ammonia.
I’m hip deep reading the stuff that’s out there on Masks, Virus, 1917, World Wars, Spanish Influenza and then I went to a freaking medical dictionary and there it was.
virus is agent that is “filtrable”
https://medical-dictionary.thefreedictionary.com/virus
Excerpt
virus [vi´rus]
any member of a unique class of infectious agents, which were originally distinguished by their smallness (hence, they were described as “filtrable” because of their ability to pass through fine ceramic filters that blocked all cells, including bacteria) and their inability to replicate outside of and without assistance of a living host cell. Because these properties are shared by certain bacteria (rickettsiae, chlamydiae), viruses are now characterized by their simple organization and their unique mode of replication. A virus consists of genetic material, which may be either DNA or RNA, and is surrounded by a protein coat and, in some viruses, by a membranous envelope.
