Duke Berkefeld Gravity Water Filter System
The Duke Berkefeld is a popular mid-size gravity water filter that offers an excellent balance between capacity and countertop space. It’s ideal for households of 3–4 people who want reliable, everyday water filtration without the need for electricity or complicated installation.
With a storage capacity of approximately 2.25 gallons (8.5 liters), the Duke Berkefeld provides a steady supply of clean drinking water for everyday needs such as drinking, cooking, and filling reusable bottles.
Each system includes two genuine British Berkefeld Ultrasterasyl ceramic filters, which combine a micro-porous ceramic outer shell with activated carbon filtration. This multi-stage design helps reduce bacteria, sediment, chlorine, and other common contaminants while improving the taste and clarity of drinking water.
The system is constructed from highly polished 304 food-grade stainless steel, giving it a durable and classic design that fits comfortably on most kitchen counters. When fully assembled, the Duke Berkefeld stands approximately 19.25 inches tall with an 8.5-inch diameter, while the chambers nest together for convenient storage or transport.
If you are looking for a reliable gravity water filtration system that provides more capacity for families while maintaining a compact countertop footprint, the Duke Berkefeld is an excellent everyday solution.

Water Contaminants This System Helps Address
Many municipal and well water sources can contain contaminants that affect water quality, taste, and safety. British Berkefeld ceramic filtration technology helps address several of the most common issues found in drinking water.
Bacteria
The micro-porous ceramic shell physically blocks bacteria, preventing them from passing through the filter.
Chlorine
Activated carbon helps reduce chlorine used in municipal water treatment, improving taste and odor.
Sediment & Turbidity
The ceramic structure captures fine particles such as sediment and rust that can make water appear cloudy.
Microplastics
Fine filtration media helps reduce small plastic particles that may be present in some water supplies.
Organic Compounds
Activated carbon helps reduce certain organic contaminants that can affect taste and water quality.

What a difference in the taste of the water! Used a Brita for years. Worth the cost.

Easy set up! I was a bit worried how long it would take for water to flow through filters, but once they are saturated it’s great. Happy we made the purchase. Clean, clear water.

Bought this to replace a travel Berkey. I live alone, but in addition to my drinking water, I use filtered water in my espresso machine, to cook with, and in my cat’s fountain. I was refilling the smaller size Berkey 1-2x per day, which got annoying. I had already tried the ceramic filters, but since they were smaller than the black carbon Berkey/Boroux filters, I was overfilling the Berkey. So, I decided to upgrade! Even though it’s bigger, it really doesn’t take up a lot more space. It still fits on my counter, and now I have more water. So this is not overkill for one person who drinks a lot of water & wants to cook with it vs tap. I’m very happy with the filters, I have really good quality tap water (Puget Sound area) but my particular city water tastes like a public pool if not filtered. Now it tastes great and is healthier! Also love the backstory on these filters. They’re easier to clean than the carbon filters, and I actually prefer to replace them every 6 months (vs 12 with the carbon filters), just to keep things cleaner. Every time I sterilized the container I wondered if putting several-month-old filters back in made sense.

This is the perfect size for 2 adults and 2 pets. Not too big or too heavy to handle. I learned that you have to be patient as it drains very, very slow into the lower chamber. The filters are great at getting rid of chlorine, nanoplastics and a lot of other bad stuff. The taste of the water is extremely delicious and absolutely great for coffee. After spending days and days of research on how to make my drinking water healthy, I am so fortunate to discover British Berkefeld. I now do not have that horrible municipal chlorine taste and I no longer worry about ingesting nanoplastics. I would definitely recommend the British Berkefeld countertop water purification system, a practical solution to rid chlorine, nanoplastics, ect. in drinking water.

So far the system is working as advertised as the saying goes. I’m new to the technology but have been researching anything I can think of and have been satisfied the British Berkefeld system was a wise decision. I would readily recommend it to anyone who wants to improve the quality of their water.
One side note: I used to live in Great Falls, Montana where there exists one of the largest (maybe THE largest) natural spring in the world (Giant Springs). The water comes up from the ground and the water is sourced from a mountain range called the “Highlands” about 35 miles away. It takes 400 years for the underground water to reach the spring. The Berkefeld system reminds me of how great the water from Giant Springs tastes!

We purchased the Duke Berkefeld with a stand and 7″ sight glass spigot. It was easy to clean before installing the filters and filling it for the first time. The water is fantastic. No chlorine odor or taste. Brewed coffee and tea tastes much more flavorful. The only suggestion I have would be to put graduations on the sight glass spigot to estimate how much water to put into the upper chamber.
Mark Alred –
Excellent product

We got the 2.5 gallon with ultra-sterasyl filters for our 2 person household. We use it for drinking water and cooking water. Best tasting water I’ve ever had. Previous house had RO filter and somehow this tastes better than that. I recommend you get the spout with the water level indicator: we did not and it is fairly annoying not knowing how much water is inside unless you peek.
Kate K. –
I really like my Duke water filter, however I did not order the stainless spigot with glass and definitely should have. Due to the long filter time, I need to keep my unit full. I thought I could “overfill” the chamber, keeping the bottom chamber full and allowing additional water to sit in the top chamber. I found out the hard way that this causes it to leak between top and bottom chambers. Great tasting water, definitely recommend this, but get the stainless and glass spigot.

I’m very happy with the quality of my water. It has made a big difference in my health and water intake. I had some trouble with assembling it and required help and I have not been able to register my filter because there’s no visible number on the equipment. I’m not sure when I’ll need to replace the filters as I live alone and don’t use it as often as normal. I would appreciate assistance with these concerns but I highly recommend the filter, it’s the best water system I’ve found!!

I had a very good experience, as shipping was super fast and I love the product. My spring water tastes amazing. Thank you!

Love this. The water tastes so much better. I make my ice cubes with it as well. So easy to clean. My family drinks so much more water with it sitting out.

The filter system is as described on the website and currently working well and I’m hoping the filters last as long as advertised. There are some negatives. The sticker on the front leaves residue so I had to use GooGone to remove it. The directions about first time use that were included in the package were incomplete. Hopefully the directions that are included with the system (and individual filters) can be updated to include this information so that people aren’t wasting time trying to troubleshoot on their own, reinstall parts, etc. The directions did not state that water has to be added to cover the filters and it is normal to take 12-24 hours the first time you run the water through. I also feel that for the cost of the system, the spout with the glass water level bar should be included. Otherwise, you’d have to lift off the top part to see the water level which is not only inconvenient but leaves fingerprint smudges that you’d have to keep cleaning.

My first experience with a gravity filter, and I am very pleased. Tap water is now delicious.

Very nice unit and easy to set up. Purchasing the stainless steal spout that measures the amount of water used really helped.
