Actually the most detailed study of masks and Covid19 spread did show that masks work but only for a relatively short time. In close face to face proximity to an infected person, if only one person had a mask, protection was about 20-30 minutes before a sufficient viral load was transmitted to the uninfected person. If both people were wearing masks, the time increased to just a bit over an hour.
N95 Masks can work for a short period but are not very efficient if you are near an infected person for any significant amount of time.
While a mask cannot stop all COVID from passing through, it can increase the time it takes for a sufficient viral load to pass on to an uninfected person. Viral Load is the key and it is something many people are not understanding. Everybody has probably ingested some COVID virus but not in sufficient viral loads to actually make them sick.
Literally just stop with the garbage. The most detailed review did no such thing, in fact it showed they were ineffective. Cochrane is literally the established leading standard of medical studies and reviews. The study found.. and I quote!
“The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks.”

Also laying out provisos and qualifiers like 20- 30 minutes and against close proximity, and note even stating what kind of mask, literally is nothing more than trying to fabricate a supporting narrative.
You know full well masks were presented as a cure all, the intent to wear in all social settings and no one was expected to real an N95 only the stupid paper ones. Stop with the sophistry!
RE you stating: “While a mask cannot stop all COVID from passing through, it can increase the time it takes for a sufficient viral load to pass on to an uninfected person. Viral Load is the key and it is something many people are not understanding.”
Do you have any data to support this? I think is is only theoretical, particularly for C19. the infective dose likely can sit on the head of a pin....besides, that agreement is mute cause data shows masks don’t work (enough viruses go through or around masks to infection you). N95 masks are likely helpful for large bacteria size infections...like tuberculosis.
Consider this:
• Many studies have been conducted that provide information on the minimum infective dose (MID) of human viruses. However, due to differences in the epidemiology and culture methods for each virus and differences and limitations of experimental procedures, estimations of the MID should be interpreted with caution (Food Environ Virol. 2011; 3:1–30 doi:10.1007/s12560-011-9056-7). Notwithstanding these limitations, the MID of respiratory and enteric viruses appears to be low and should be viewed in relation to the likely host characteristics of the at-risk population of interest. These include host factors such as age, health status, and previous exposure to the virus; pathogen factors such as virulence of the viral strain and passage in cell culture; and experimental factors such as the route of inoculation and the sensitivity of the assay used to determine the viral dose administered.
Baloney. Covid was never a circulating respiratory disease.
