The Big Berkey is our most popular water filter system here at, and for good reasons. It's the perfect size! The functionality of the Big Berkey makes it so versatile that it works for several situations. It’s 2.25 gallon capacity can provide plenty of water for medium-sized families of one to four people, without taking up precious counter or fridge space. This unit fits easily in the kitchen, RV, tiny house or off-grid cabin! The size of the Big Berkey is 21 inches tall and eight and half inches wide. 

Capacity: 2.25 Gallons (8.5 L)
Material: 304 AISI Stainless Steel
Finish: High Polish Stainless Steel

Its size and holding capacity make the Big Berkey a highly adaptable unit. It is ideal for medium-sized families of one to four people, and this Berkey filter model is compact enough to easily fit into an RV, tiny house, or cabin.

In emergencies, the Big Berkey system is also large enough to keep over a dozen people hydrated with purified water. Just be sure to use all four filters.

Since the Big Berkey holds 2.25 gallons, it will take about two hours and fifteen minutes for the entire upper chamber to be filtered through to the bottom chamber. Of course, there are some variances, and it may filter faster or slower based on different scenarios.
