What is the difference between a water filter and a water purifier?

LifeStraw purifiers are designed to remove bacteria, parasites, and viruses through ultrafiltration technology (~0.02 microns). Microfilters remove bacteria, parasites, and microplastics but not viruses. LifeStraw purifiers with virus removal provide comprehensive protection for the harshest water conditions.

How does LifeStraw test its purifiers?

LifeStraw purifiers are tested using protocols aligned with WHO, US EPA, NSF, and WQA standards. The brand emphasizes log-removal performance framing, maintains an ISO-certified in-house water lab, and conducts external accredited lab testing. Evidence dossiers document performance for transparency and credibility.

What contaminants do LifeStraw purifiers remove?
