The Big Berkey is our most popular model of water purifier. It is for the average size family of 2 to 4 people.

It stands 19.25″ tall, is 8.5″ in diameter, and holds 2.25 gallons of purified water.  It generally comes equipped with 2 Black Berkey filter elements and will filter up to 3.5 gallons* per hour.  It can easily be expanded to hold 4 filter elements to increase the flow rate to almost 7 gallons per hour.  

Read more about the Berkey filter elements HERE and HERE.

*Flow Rate is based on the upper chamber being full of water.
