The Imperial Berkey comes with 2 Black Berkey Purification Elements but is expandable to 6 elements. This system has a storage capacity of about 4.5 gallons (17 liters) and when in use it stands 25.75” in height with a diameter of 10”. The upper chamber nests within the lower chamber for transport and stands only 17” in height. If configured with just 2 purification elements, it will purify 5.5 gallons an hour. This doubles with 4 elements. If you expand your Imperial to the maximum capacity of 6 elements, it will purify 16.5 gallons of water per hour!
Due to state regulations, this unit cannot be shipped to California or Iowa.
