Can straw filters remove viruses?
Reviewer consensus
Most hollow-fiber straw filters in this category (Sawyer, LifeStraw Peak/Personal, Membrane Solutions) are rated for bacteria and protozoa, not viruses. Reviewers note the LifeStraw Family gravity purifier is one of the few in this lineup that claims virus removal, which matters more for international travel than North American backcountry use.
