The versatile Imperial Berkey system is the ideal system for use with small to medium sized groups, at home, churches, hospitals orphanages, for outdoor activities or during unexpected emergencies.

This powerful system purifies both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. Perfect for outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available.

The Imperial Berkey system removes pathogenic bacteria, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and unhealthy minerals such as lead and mercury. This system is so powerful it can remove red food coloring from water without removing the beneficial minerals your body needs. Virtually no other system can duplicate this performance.

Constructed of highly polished 304 stainless steel, the system comes complete with two Black Berkey purification elements and utilizes the latest technological advances. This system has a storage capacity of about 4.5 gallons (17 liters) and when in use it stands 25.75" in height with a diameter of 10". The upper chamber nests within the lower chamber for transport and stands only 17" in height.

Configured with two Black Berkey purification elements the system will purify up to 5.5 Gallons (20.8 liters) per hour*. This system can be expanded to use up to six purification elements and is capable of purifying up to 16.5 Gallons (62.5 liters) per hour*.

*Lifetime warranty applies to stainless steel tanks, lid, lid knob, plugs, and plastic spigot. Lifetime warranty does not cover any filters nor any accidental damage. Black Berkey filters have a 2 year pro-rated warranty.

Black Berkey Purification Elements

Black Berkey Purification Elements are more powerful than any other gravity filter element currently available. In fact, we tested the Black Berkey purification elements with more than 10,000 times the concentration of pathogens per liter than is required by standard test protocol. This concentration of pathogens is so great that the post filtered water should be expected to contain 100,000 or more pathogens per liter (99.99% reduction - the requirement for pathogenic removal). Incredibly the purification elements removed 100%. Absolutely no pathogens were cultured from the effluent or were able to be detected, even under an electron microscope, setting a new standard in water purification.

Black Berkey purification elements are so powerful, they can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other filtration element can duplicate this performance.

No need for expensive disposable filters. Black Berkey purification elements are re-cleanable. When the flow rate decreases simply brush the Black Berkey purification elements with a ScotchBrite pad under running water, reinstall and your system is again ready to purify water. Each durable and efficient purification element will last for up to 3,000 gallons (6,000 gallons per set of two) and provide years of efficient water purification. What's more, the unique Black Berkey purification elements are self-sterilizing.

The powerful Black Berkey purification elements also remove or reduce pathogenic cysts, parasites, harmful or unwanted chemicals such as herbicides and pesticides, VOCs, detergents, organic solvents, trihalomethanes, cloudiness, silt, sediment, nitrates, nitrites, heavy metals, foul tastes and odors, yet they leave in the healthful and beneficial minerals that your body needs.

    Great Company Great Product

    Posted by Eddie and Gail on 11th Oct 2016

    We bought the Berkey Imperial because our area has a Chromium 6 alert for the water and this filter takes it out! Very happy about that. When the unit came the glass water level spigot was cracked. I notified the company and after sending them a picture of it they immediately sent a new replacement! Great Service. We love the size because we have lots of people in the house and the water tastes great! Thanks for making a quality product.

    We are taking it to our cabin.

    Posted by Diane on 15th Feb 2016

    We bought the Berkey for out cabin and have not used it yet. After some research we are convinced that it is the best. We do not use the water in our home for drinking or cooking. We get our drinking water from an artesian well. This was a Christmas gift from our children. We will all use it at the cabin.

    Pure Water - Easy to Setup

    Posted by Ron on 25th Jan 2016

    I purchased the Berkey System and the water is great. In addition to the regular filter, I also purchased the additional fluoride filter and the water is truly amazing. I had a difficult time drinking water from our refrigerator which was filtered and found out that it did not remove fluoride or residual traces of arsenic. With the Berkey fluoride filter it does both. I have no problems drinking the water and am also prepared if our city water supply is ever compromised.

    worth the initial expense

    Posted by michael F Shea on 10th Jun 2015

    Initially it's tough spending close to $400 but worth the cost health wise and pays for itself in less than a year! Then I believe it cost .17 per gallon!

    Peace of mind for my family

    Posted by Valerie on 6th Mar 2015

    I've been wanting a Berkey for a long time, and finally purchased one last month. I couldn't be happier with the investment in my family's health. The water from our Berkey is delicious and with the fluoride filters in place, I have one less toxin to worry about in our household. We got the Imperial Berkey, because we are a family of 7 plus 2 pets. It's serving us well, and we are filling it nightly.

    Berkey Imperial

    Posted by Betty on 23rd Sep 2014

    It is difficult to assign a numerical rating. The product is easy to use, it functions as advertised and was highly recommended by a respected source. However, unless I have the end product tested, how do I really know how pure the water is? I'm trusting that it is pure.

    Best Investment Ever Made!!

    Posted by Michele on 13th Jun 2014

    My husband and I are very much into health and survival preparedness. Being that clean, pure water is a mainstay to living, we had wanted to invest in a Berkey for years! When a sale opportunity arose, we knew this was our chance. This is by far, the absolute most worthwhile purchase we have ever made. My first glass of pure water, I remarked "There's no smell!" The price is right and the shipping was so fast, i was shocked. Wonderful company to do business with and plan to in the future. If you're considering a Berkey, go for it! You will not be disappointed.
