Aquasana AQ-5200 vs Big Berkey
The Aquasana wins on verified contaminant reduction. The Berkey is cheaper per gallon, but unverified lead and PFAS claims cannot earn certification credit - cheap water you cannot verify is not a bargain.
Big Berkey is genuinely cheap per gallon and popular, but its contaminant claims are 'tested to' lab results, not certifications on a public database. The Aquasana is certified for lead and PFAS.

FAQ
- Is the Berkey a bad filter?
- We do not say that. We say its contaminant claims are not third-party certified, so we cannot score them as verified. If Berkey obtained certification, its score would rise.
