The bottom line

What the product listing won't tell you

Know before you buy

Big Berkey ranks last in this category due to documented aluminum oxide leaching from its PF2 fluoride filter at 1.4 PPM above Tap Score's Health Guidance Level — combined with Duke 2020 PFAS failure and zero NSF certification. The 6,000-gallon filter life and electricity independence are genuine practical advantages. R3 does not recommend Big Berkey as a primary daily drinking water filter until the aluminum leaching issue is resolved or PF2 filters are removed.

You use Black Berkey elements ONLY (no PF2) — this eliminates the aluminum leaching source, though fluoride reduction is then unverified.
Emergency preparedness or off-grid use where filter longevity and electricity independence are the primary requirements.
You have access to your own independent Tap Score testing to verify output water quality for your specific water source.

Skip if

You're using or plan to use PF2 fluoride filter elements — the documented aluminum leaching above Health Guidance Levels is a chronic daily consumption risk.
Your water has PFAS, lead from service lines, or other documented contamination — NSF certification is the required consumer protection standard.
You live in California — most Berkey models are banned due to lack of NSF certification.
Any of Mamavation, EWG, IRLFY, or GtGS recommendations matter to your purchasing decision — all four explicitly do not recommend Berkey.
