LifeStraw Home vs Brita Elite
In our view the Brita Elite wins on what can be verified: it is certified to NSF/ANSI 53 for lead, where we found no active third-party certification behind LifeStraw's contaminant claims. We score proof, not the length of a claim list. If LifeStraw certified its claims, its score would rise.
LifeStraw markets reduction of bacteria, parasites, microplastics, lead, and PFAS, but in our reading those claims rest on the brand's own 'tested to' protocols rather than an active NSF, WQA, or IAPMO certification we could verify in a public registry. The Brita Elite makes a shorter list of claims, but they are genuinely certified.

FAQ
- Does LifeStraw not work?
- We do not say that. We say we found no active accredited certification we could verify for its contaminant claims, so under our rubric they earn no credit. That is a statement about verification, not about whether the product performs in a lab.
- Why does the Brita Elite score higher with fewer claims?
- Because we credit certifications, not claim counts. The Brita Elite's lead and metal claims are certified on a public database; a longer 'tested to' list is not.
