You won't often catch covid from stray particles but from the person breathing next to you, which these filters can't help. This study was in a hospital where everyone is wearing serious PPE, so its a super edge case to get rid of covid in the air because the main use case of catching covid has been handle by plain old PPE. This doesn't have sweeping applicability. It won't stop covid among the general population. Its for maybe hospitals that are on super covid lockdown that want a little more protection for their most vulnerable patients. We get rid of covid through mass vaccination like any other virus. There's no shortcuts for those who refuse masks and vaccines.

What if the air is being actively refreshed and filtered. I believe this is what needs to start happening in most indoor environments. This would definitely help with reducing the amount of cases.

As far as I can tell, COVID has two predominant modes of spread: - Extended time indoors, with high viral loads. It spreads ridiculously well with no protection (even among the vaccinated). - Isolated superspreader events, where one person infects many, even with distant contact. Filters would seem to target the latter more than the former.

>You won't often catch covid from... how do you know? it seems like most cases are attributed to the nebulous "community spread" and nobody is really sure who they're coming from or how we're catching it. maybe we are getting it from the person breathing near us - if masks help, i don't see a reason that improved air filtration wouldn't.

  Because understanding how viruses spread is a solved art. None of this is "unknown."

    In the same way that people are dumbfounded that natural immunity from having it is superior than the vaccine. It’s as if we all forgot how viruses work.

      In terms of safety, vaccines are much better then getting COVID. One of the big factors of "better protection" of immunity gained after recovering from the virus is survivor bias. In data about mortality after reinfection there are no people who died after getting it for the 1st time. This leaves only ones who had body strong enough to recover. There's no surprise that later that group fares better.

  All the data suggest that its not someone breathing on you in passing that's going to result in covid infection, but spending long periods with someone indoors in close proximity. Within a half hour in the massive grocery store? I would be shocked if you caught it. Drinking in someones living room, swapping stories within arms length, swapping spit flecks for 5 hours straight? Definitely going to spread everything you have in such a small enclosed space where the viral load is able to reach a much higher concentration over a long period of time.
