There is uncertainty about the effects of face masks. The low to moderate certainty of evidence means our confidence in the effect estimate is limited, and that the true effect may be different from the observed estimate of the effect. The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks. There were no clear differences between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers when used in routine care to reduce respiratory viral infection. Hand hygiene is likely to modestly reduce the burden of respiratory illness, and although this effect was also present when ILI and laboratory-confirmed influenza were analysed separately, it was not found to be a significant difference for the latter two outcomes. Harms associated with physical interventions were under-investigated.
Welp, time for me to buy a new mask cause I accidentally tossed my old one out when I replaced my old purse. :|
Disposable KF94’s are the way to go. I re-use them as safely as I can, because I’m not rich, but then discard them when they become compromised
Cloth masks don’t do shit anyway. Neither do N95s apparently. You are out of date on the literature.

Counterpoint: Wearing and maintaining a clean mask takes nearly zero effort and provides peace of mind for a lot of people.
