Step 1 - Choose the system capacity
To the size of your needs
Berkey® water purifiers are available in seven different sizes. The system you choose should take into account your space size, the number of people in your home and how you will use the pure water (for drinking only or also for cooking, hygiene, pets, etc.).
How to calculate the necessary capacity?
For typical daily use, multiply the number of people in your household by 1.9 liters. In an emergency situation, this capacity should be doubled for the same number of people, either by choosing a larger capacity system or by refilling your Berkey® filter more often. You will then have determined the minimum recommended amount of water you can use each day.
For example, for a household of 4 people: 4 x 1.9 liters = 7.6 liters, plus the amount of water used for cooking, coffee making, etc. The minimum choice would therefore be the Big Berkey® model with a capacity of 8.5 liters.

Black Berkey® filters supplied as standard.
Slots for optional Black Berkey® filters.
Note : PF-2 filters do not require additional slots, they fit on the Black Berkey® filters.
Step 2 - Choose the number of filters
Berkey® systems come standard with 2 Black Berkey® purification elements (with the exception of the Go Berkey® kit which includes a single filter). Each additional set of 2 filters decreases filtration time and increases the filter element life.
See the chart below to see the configuration options for each system. Please note that you can order Black Berkey® purification elements at any time. We recommend that you always have a backup set in case of emergency.
