Pick the Right Size & Number of Filters

Use this guide to match your household to the ideal Berkey® unit and BOROUX Foundation™ filter count.

Household Size Recommended Unit Capacity Filters (Good) Filters (Faster Flow) Typical Refill Rhythm*
1–2 people Travel compact ~1.5 gal 2 elements ~1× / day
2–4 people Big most popular ~2.25 gal 2 elements 4 elements ~1–2× / day
4–6 people Royal ~3.25 gal 2 elements 4 elements ~1–2× / day Selected
6–10 people Imperial ~4.5 gal 4 elements 6 elements ~1–2× / day
10–16 people Crown max capacity ~6.0 gal 6 elements 8 elements ~1–2× / day
How to choose:
  • More elements = faster flow and more headroom for busy kitchens or guests.
  • If you make lots of coffee, cook frequently, or fill pet bottles, consider the “Faster Flow” column.
  • For travel, off-grid, or variable-demand homes, size up one unit for fewer daily refills.
*Refill rhythm is a practical estimate under typical use; your routine may vary with daily intake and cooking.
