while I am sure there could be a better mask, the N99 I wear is pretty comfortable. Cleaning the air will never directly deal with Covid though. Short range interaction with people is the largest transmission source, indoors and out, because of the intensity of the aerosols so close to the source a partial second away, while air cleaning takes 15 minutes. Technology that immediately shows whether covid is in the air… that might change things. Marcos (npub1gdt…g9jd)
