The Big Berkey is the most popular product from Berkey Filters and is able to filter 3.5 gallons per hour with two purification elements. It is designed for both home and outdoor use and is one of the most reliable filters in the industry.

Product Description

When we review water filters we do so with emergency preparedness in mind, not regular home use. So even though the Big Berkey can be a great home water filtration product, we do not rate it against such companies as Brita, Culligan, and Pur.

The Big Berkey is the most popular filter in the Berkey line of products. Berkey keeps it pretty simple and has produced filtration products that correspond to how many people can use the filter. The smallest Berkey filter is the Travel Berkey (rated for 2-4 people) while the largest is the Crown Berkey (rated for up to 150). We have chosen to review the Big Berkey because of its popularity and fit (8-16 people depending on how many internal filters you put on it).

How does it work?

Berkey filters are gravity fed, which simply means you pour water into the top of the unit and the force of gravity will pull the water down through the filters. It’s a very easy process, and it has several advantages over other types of filters that use pumps or electricity. Pumps can break down and there may be times when you don’t have access to electricity.

The Big Berkey can filter water at a rate of 3.5 gallons per hour, which should be plenty for most applications and family sizes. It removes bacteria, parasites, herbicides, pesticides, solvents, nitrates, nitrites, lead, mercury, chlorine, VOCs, and even fluoride. Obviously, the dirtier the water you put through it the longer it will take and the more frequently you will have to clean the filters.

Berkey products are made from 100% stainless steel, which will hold up better than plastic or composite. It may scratch, but it’s only cosmetic. The Big Berkey is about the same price as other comparable filters but packs in the most features and actually has the lowest cost-per-gallon rating of any of the gravity-fed filters.

Our Opinion

If you don’t have a water filter, you need to get one. It’s that simple. The average human needs many gallons of water each day for drinking and sanitation–and there is no way you can store that much water. As long as you have access to some source of water, the Big Berkey can get you through a natural disaster or even social unrest.
