Our take
Berkey systems are gravity-fed stainless steel containers with replaceable Black Berkey filter elements. The filter element is the long-lifespan workhorse — 6,000 gallons per pair. Independent testing covers many heavy metals, pharmaceuticals, and some PFAS reduction. Note: Berkey publishes its own testing rather than holding NSF P473, so we cite their published lab reports rather than NSF certification.
Pros
- Long filter element life
- No electricity, no plumbing
- Stainless construction
Cons
- Self-published testing rather than NSF P473
- Slow throughput vs RO
- Bulky on a counter
