How do LifeStraw water filters work?

LifeStraw products use hollow fiber membrane filtration technology. Microfilters (~0.2 microns) remove bacteria, parasites, microplastics, and dirt. Ultrafilters (~0.02 microns) can additionally remove viruses. Some systems combine filtration with activated carbon and ion exchange to reduce chemicals and heavy metals like PFAS and lead.

What contaminants do LifeStraw filters remove?

LifeStraw microfilters are designed to remove bacteria, parasites, microplastics, and dirt/silt. Ultrafiltration products can remove viruses in addition to bacteria and parasites.

Performance varies by product—check product-specific documentation for exact specifications.
