Imperial Berkey Water Filter System - 4.5 Gallon

Enjoy high-capacity gravity-fed water filtration with the Imperial Berkey Water Filter System. With a generous 4.5-gallon (17-liter) capacity, this stainless steel system is designed for everyday use by approximately 4–8 people, making it a practical choice for larger households, offices, small groups, RV use, and emergency preparedness.

The Imperial Berkey comes standard with 2 Black Berkey Elements and can be expanded to accommodate 4 or 6 Black Berkey Elements for increased filtration flow. Its highly polished stainless steel construction offers durability, while the upper chamber nests inside the lower chamber to reduce its height for storage and transportation.

No electricity, plumbing, or water pressure is required. Simply fill the upper chamber and allow gravity to move the water through the Black Berkey Elements into the lower chamber for convenient dispensing through the included spigot.
