  • Perfect for everyday use, outdoor activities, and a must in hostile environments where electricity, water pressure, or treated water may not be available.
  • The Big Berkey system entirely removes pathogenic bacteria, cysts, and parasites and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222, and trihalomethanes.

This system comes standard with the following:

  • Stainless steel canister
  • Set of 2 Black Berkey filters 
  • Standard spigot
  • 2 blocking plugs

 The best thing about our Big Berkey water filter is it's a perfect size to satisfy enough water for 2 to 3 people. Its low profile size fits comfortably in most kitchens. The unit is constructed of high-quality stainless steel.

This system can hold up to 4 Black filters and 4 PF-2 fluoride filters, which are completely optional. It can not just be used for home but as well as travel and outdoor use for purifying both treated and untreated raw water.

It is also capable of reducing fluoride in your water when used with Berkey's optional PF-2 fluoride filters. The fluoride filters screw onto the Black filters.

Berkey systems are freestanding water purifiers that sit on a countertop or stand. Simply pour water from virtually any source into the top chamber of the system, and dispense purified water easily from the lower chamber through a handy spigot. The systems are easy to use—no electricity, tools, or plumbing is needed.

The Black Berkey filters used in the Big Berkey will reduce or remove pathogens, parasites, herbicides, pesticides, VOC's, heavy metals, as well as bad tastes and odors. No other filters can duplicate this performance. Black Berkey filters can be cleaned by using a Scotch Brite pad under running water.

Big Berkey: A Powerful Water Purifier

We know that tap water has already been treated to make them safe to consume. However, that water still has to go a long way from the water treatment plant to your home.

This water still has to go through miles and miles of pipes, and it could encounter a lot of things on its way, so how sure are we that it is really safe to consume?

The thing is, the water that we drink should be labeled safe and healthy. So how can you turn tap water into something healthy?

The answer: a home water filtration system and one of the most trusted water filters is the Berkey Water Filters.

The Berkey understands that choosing the right water filter for your home can really be a hard task, so we offer you products that are everything you are looking for.

Filters of Berkey systems are made in the USA. Since we already have an established reputation in the industry and the results of their filtration tests are outstanding, we hold a gold standard when it comes to gravity filtration systems.

There are different sizes to choose from, but all products promise an easy and reliable experience. In addition, its ability to be portable is one of its most outstanding features that are highly recognized all over the globe. Waters can be your company whenever you go for camping trips, vacations, and any outdoor activities for that matter.

If you want a Berkey water filter that could serve your family of 4 or 5, then the Big Berkey Water filter is the one you should go for.

It is relatively affordable considering all its features and the benefits you will get. It has been proven that you can save a lot of money with Berkey instead of other water purification competitors.

Understanding NSF Standards 42 and 53
It is important to note that NSF Standards 42 and 53 do not certify that a filter removes pathogenic bacteria or other contaminants; the standards only require reduction.

NSF Standard 42 (Aesthetic Impurities)
Under this standard, filters are certified to reduce (but not remove) aesthetic impurities such as chlorine and taste/odor in water that is already biologically safe and of known quality. Therefore, this certification does not pertain to the purification of non-potable water. Moreover, this standard is only intended to reduce substances affecting the aesthetic quality of the water only or to add chemicals for scale control, or both.

NSF Standard 53 (Health Effects)
A filter can be awarded NSF Standard 53 certification if it treats (and effectively reduces) at least one of the contaminants with health effects (such as lead and other heavy metals or volatile organic compounds), as detailed by the Environmental Protection Agency (EPA).
Also, note that reducing one unhealthy water contaminant (a 25% reduction qualifies as reducing) to qualify for NSF Standard 53 is nothing when compared to the powerful contaminant removal capability (>99.9 %) of Black Berkey® Purification Elements.

The Big Berkey Water Filter

Big Berkey is a versatile water filtration system, and it is ideal for home use of a small or a medium-sized family, but you can also bring it on your travels or other outdoor activities like camping.

It is a powerful system that can purify both treated water and raw, untreated water from sources like stagnant ponds, streams, and remote lakes, and it does not require electricity. That's why it is perfect for everyday use. 

The Big Berkey filtration system is very powerful. It is classified as a purifier. It can remove cysts, pathogenic bacteria, and other dangerous chemicals like pesticides, herbicides, organic solvents, and VOCs trihalomethane or THM and radon 22.2.

How Big Berkey was Made

The Big Berkey has been constructed with the use of 304 stainless steel that has been highly polished. The system of this water filter is equipped with two purification elements. It also makes use of the latest advances in filtration system technologies.

This is a home system that would serve your family; that is why it has a storage capacity of 2.25 gallons or 8.5 liters.

The flow rate of the Big Berkey Water filter system varies on the number of Black Berkey purification elements it has installed.

Flow Rate is a term used to describe the ability of the water system to purify a specific number of water gallons per hour.

When there are 2 purification elements installed in the Big Berkey system, it can purify 3.5 gallons of water per hour. On the other hand, the results double when 4 purification elements are installed in the Big Berkey. With 4 purification elements, the Big Berkey water filter system can purify up to 7 gallons of water per hour.

The Big Berkey has been configured with the use of two purification elements from the Black Berkey, and it has the capacity to purify up to 3 and a half gallons or 13.3 liters per hour.

Its system can also be expanded into four purification elements making it capable of purifying 7 gallons or 26.5 liters of water per hour.

The price of the Big Berkey is most definitely cost-effective. Each of the durable Black Berkey water filters can last up to approximately 3,000 gallons of water, which means that the two will last for approximately 6,000 gallons.

That is actually a lot longer than most water filter solutions you can find in the market. If it can provide 10 gallons a week, that could be equal to 11 and a half years of safe and healthy drinking water for you and your family.

Glad to have it with the unknown elements in the water these days. Water supply in the KC area is the river and or runoff from fertilized fields. The Berky gives me a sense of security when I drink water. Thanks

Douglas McVey
Great tasting!

Extremely happy with our new Berkley filter system....the water tastes great and easy to use. Bought one for our daughter as a house warming gift...Don't tell anyone.

Love the Berkey

We recently bought the 2.25 gallon Big Berkey water filtration system. We love the peace of mind it gives us knowing the water we are drinking is pure. I also like the portability of the system as you can take it on camping trips, etc. The 6000 gallon filtration capacity of 2 filters will provide enough drinking water for about 8 years for my wife and I!

Poor Customer Service

After receiving word that my order had shipped....I waited....and I waited.... In ten days I called, to find out that the order had been pulled before shipping, as the felt that the address was giving the wrong zip code. No one called, they "felt' it was not right, and set it aside.
I have it now, but had to order a siphon, as the newer home faucets will not work. Can't explain better than that, as my husband was in charge of this project. We finally have the siphon, at additional cost and are up and running. We all know the quality of the Berkey, that is why we pay top dollar for it. That having been said, wake up customer service. I am still waiting to hear how sorry they were regarding the mixup. Zip and address were correct, by the way.

Jerry Lybarger
works great

Use at our farm on well water that is already cleaner than our home city water (which is as clean as it gets in this country) except for one thing and the Berkey is cleaning that up well. Love it. Don't need to buy water anymore.
