Overview of the Big Berkey Gravity-Fed Water Filtration System

The Big Berkey is a gravity-fed water filtration system that uses a combination of ceramic and carbon filters to remove contaminants from drinking water. It’s capable of filtering both treated and untreated water sources, making it a versatile option for households and emergency preparedness situations.

Key Features

  1. Filtration Capacity

The Big Berkey system can filter up to 3.25 gallons (12.3 liters) of water at a time. With a flow rate of approximately 3.5 gallons per hour, it can provide enough clean water for a family of four.

  1. Filter Life

The Black Berkey purification elements have a lifespan of up to 6,000 gallons per pair, meaning you won’t need to replace them frequently. The optional PF-2 Fluoride and Arsenic Reduction Filters have a shorter lifespan of approximately 1,000 gallons.

  1. Contaminant Removal

The Big Berkey system is known for its ability to remove over 200 contaminants, including bacteria, viruses, heavy metals, chlorine, and volatile organic compounds (VOCs). It also reduces fluoride and arsenic when paired with the optional PF-2 filters.

  1. Portability and Design

The stainless steel design not only gives the system a sleek look but also makes it portable and durable. With no electricity or plumbing required, the Big Berkey can be used anywhere there’s access to water.

Installation and Maintenance

Setting up the Big Berkey system is simple and requires no tools or professional assistance. The detailed instruction manual guides you through the process of assembling and priming the filters. Regular cleaning and maintenance are crucial to ensure optimal performance. Cleaning the lower chamber every few months and replacing filters according to their lifespans will keep your system running efficiently.


The Big Berkey filtration system effectively removes contaminants from water, ensuring it’s safe for drinking and cooking. Users often report improved taste and odor, as well as a noticeable difference in water clarity. However, it’s essential to note that the system’s flow rate may decrease over time if filters are not adequately maintained.

Its impressive contaminant removal capabilities and ease of use make it a popular choice for families, travelers, and emergency preparedness enthusiasts. Although it may require some maintenance and filter replacements, the overall cost and performance benefits make the Big Berkey a worthy contender in the water filtration market.
