Step 1 - Choose the System Capacity

Based on Your Needs

Berkey® water purifiers are available in seven different sizes. When choosing your system you should take into consideration the space you have and the number of people in your household, and for what purposes you will be using this pure water for(drinking only or also for cooking, hygiene, pets, etc.).

How to Calculate the Capacity you need?

For regular daily use, multiply the number of people in your household by 1.9 liters. In an emergency setting, double this capacity for the same number of people, either by opting for a system with a larger volume or by filling your Berkey® filter more often. This will determine the minimum recommended amount of water you will use each day.

For example, for a household of 4 people: 4 x 1.9 liters equals 7.6 liters in total, plus any additional water used for cooking or other purposes. The minimum choice would be the Big Berkey® model.

Step 2 - Choose the Number of Black Berkey® Filters

Berkey® systems are delivered with 2 Black Berkey® purification elements as standard (except for the Go Berkey® kit which only has one filter). Each additional set of 2 filters reduces filtration time and increases the lifespan of the filtering elements.

Refer to the table below for the possible configurations for each system. Please note that you can order Black Berkey® purification elements at any time. We recommend always having a backup set in case of emergencies.
