Overview

Gravity does the work in the Berkey BER-CU2+BER-PF2, a stainless steel countertop system standing about 25.75 inches tall that filters water through Berkey's proprietary Black Berkey media without needing electricity.

Gravity filtration means no electricity or water pressure is needed. Water poured into the upper chamber filters down through the Black Berkey elements into the lower chamber by gravity alone, which is why the tall, two-chamber stainless steel build carries real weight at 12 pounds.

  • Proprietary Black Berkey filter media
  • Gravity-fed, no electricity needed
  • 6 gallon capacity
  • Stainless steel two-chamber design

Who it's for

Households wanting a large-capacity filter that keeps working off-grid or during power and water pressure interruptions, with counter space for a tall two-chamber unit.

Pros and cons

Pros
  • Gravity-fed, works without electricity or water pressure
  • 6 gallon capacity for large batches
  • Stainless steel construction
Cons
  • Tall footprint at nearly 26 inches
  • Heavier at 12 pounds than typical countertop filters

Performance notes

Because filtration relies on gravity pulling water through the Black Berkey elements rather than pump pressure, flow rate is slower than a pressurized system, but the tradeoff is that it keeps working without power or plumbing pressure.
