Agree. I'd only use it to extend my bleach supply. Filters do pretty good on bacteria, but not on virus. IMO, in the early stage of a disaster, bacteria will be the issue, but after a few days and once waste starts to build up, virus will become a problem. Once that happens, filtering followed by oxidation (with chlorine or mixed oxidant) is needed to keep water safe.
