Choosing a Berkey Water Filter System

Step 1. How do the Berkey water filter systems work?

Natural Berkey Water Filter operates as water is poured into the upper chamber. Gravity draws this water through the Black Berkey exclusive purification elements where contaminants are captured on and within theses microporous elements and are separated from the water. The purified water then collects in the lower chamber where it can be drawn through the spigot. The greater the volume of the water and the number of Black Berkey Filter Elements, the faster the flow rate of purified water. What’s more, Black Berkey elements are cleanable and can be used over and over again.

The table below shows the flow rate of purified water per system configured with the standard 2 filters and when the same system is fully expanded. All systems, except the Berkey Go, function with a minimum of 2 filters.

Model Capacity Filters Flow Rate*
Go Berkey .95 litre 1  3.8l/hr
Travel Berkey 5.7 litre 2 10.4 l/hr
Berkey Light 10.4 litre 2 15.1 l/hr
Berkey Light 10.4 litre 4 32 l/hr
Big Berkey 8.5 litre 2 13.2l/hr
Big Berkey 8.5 litre 4 26.5 l/hr
Royal Berkey 12.3 litre 2 15.1 l/hr
Royal Berkey 12.3 litre 4 30.2 l/hr
Imperial Berkey 17 litre 2 20.8 l/hr
Imperial Berkey 17 litre 6 62.5l/hr
Crown Berkey 22.5 litre 2 24.6 l/hr
Crown Berkey 22.5 litre 8 98.4 l/hr
Step 2. Which size Berkey Water Filter System is appropriate?

The best guideline for choosing which size of Berkey Water Filter is appropriate for you is that bigger is usually better providing you have the space for it. Which simply means that it’s more convenient to have a larger system as you won’t have to fill it as often. Since the higher water volume in the upper chamber increases the pressure upon the filters the water, therefore, flows through faster. The differences in cost between the various models are minimal when you consider that you will be using the same model for 10-20+ years.

Berkey Model Capacity Number of People
Go Berkey 950 ML  1-2 people
Travel Berkey 5.7 liters 1 – 2 people
Berkey Light 10.4 liters 2 – 5 people
Big Berkey 8.5 liters 1 – 4 people
Royal Berkey 12.3 liters 2 – 6 people
Imperial Berkey 17 liters 4 – 8+ people
Crown Berkey 22.7 liters 4 – 12+ people
Step 3. The Berkey Water Filter systems

As has already been mentioned, all the Berkey Water Filter systems come configured with 2 upper chamber filters, the Black Berkey Filter Elements. The filtration quality will not be improved by increasing the number of filters used in the upper chamber, but it will increase the speed of filtration and the volume of water that can be filtered. For instance, by increasing the number of Black Berkey elements from 2 to 4, the filtration speed and volume of water that can be filtered will approximately double from 22,700 total liters to 45,400 total liters.
