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.
