How to choose your Berkey

3-Steps & Done
Selecting the ideal Berkey System for your needs is simple. Chose your size, consider your elements and add enhancements.

Step 1: Select Your Housing Size

A Size To Fit Your Needs

Berkey® systems are available in seven different sizes. The system you choose should accommodate the size of your space, the number of people you want to serve and the reasons for which you will be using the water (drinking only or also for cooking, hygiene, pets, etc).

How To Calculate Use

For typical daily use, multiply the (# of people in your group) X (.5 gallons). In an emergency, multiply (# of people in your group) X (1 gallon). This is the recommended minimum amount of water you may anticipate using each day.

	Size	Will Hold	Max per Hour*
Go Berkey^® System	14″ H x 4″ D	1 quart	1 gal / hr
Travel Berkey^® System	18″ H x 7.5″ D	1.5 gal	2.75 gal / hr
Big Berkey^® System	19.25″ H x 8.5″ D	2.25 gal	7 gal / hr
Royal Berkey^® System	23″ H x 9.5″ D	3.25 gal	7 gal / hr
Imperial Berkey^® System	26″ H x 10″ D	4.5 gal	16.5 gal / hr
Crown Berkey^™ System	30″ H x 11″ D	6 gal	26 gal / hr

*This is how much water the system may produce per hour (flow rate) when fully configured with the maximum number of elements.

Step 2: Consider Your Elements

Berkey® systems come standard with 2 Black Berkey® Purification Elements (except for the Go Berkey® Kit which comes with one element). Each additional set of 2 speeds up the purification process and adds 6,000 gallons in lifespan.

Look at the chart below to see configuration options for each system. Please note that you can order additional sets of Black Berkey® Purification Elements at any time. We recommend having backup sets on hand in the event of an emergency.
