npub1gxv4vcqfp2ug07fd34t0swq4w2t9gsynu0cmelr6ktcna8xnv38qythh99 (npub1gxv…hh99) Pressurized suit, tethered by clear air supply hose. "Not for pathogens..." is the typical disclaimer from all mfr's of cartridge type respirators. Face-fit respirators, my engineering team (2010) was required to pass medical clinic "fit testing", face seal, proper exhalation valve function, with lung capacity baseline. Cloth masks have been the biggest ruse of my lifetime. Medical, engineering, all complicit. Shameful.
