You don't need to filter out the viruses, you need to filter the aerosol the viruses are sitting in. That is a major plus of Covid, verification (repeatedly) and acceptance of that fact.
- chitowneats 5y agoExcept that we know now Sars-Cov-2 transmission is airborne. As the aerosol caught in your mask evaporates, the virus sheds into the surrounding air, where it is later contracted by someone else. I think you'll be a little disappointed at the level of "acceptance" of mask wearing & efficacy going forward.
