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.

Just what I wanted, and it’s nice looking too. The size is perfect and the water filter’s deplete the top in just a couple hours. Perfect!
Julie R. –
The package arrived in a nicely protected package. Set up was fairly easy. I do wish we could see how much water is left in the bottom tank, so I am going to look for options on that now.

Perfect in all the ways!
Pamela M. –
This is something I’ve been meaning to get for a long time, and I wasn’t disappointed💕
Sally E. –
The taste is great! We followed the instructions of Ryan on facebook who said to run 6 gallons through it first. We then cleaned it again, and did a taste test with Mountain Valley Spring water, and we were not able to tell the difference which is remarkable because I am VERY picky when it comes to water. Thank you!
Jason –
Excellent product, excellent quality, excellent water quality!
Annie Heartfield –
Love it, and it’s gorgeous. The water: delicious.

Very happy so far with this water filter. Water tastes and feels so much better than our fairly good tap water! Shipping was fast and the product was packed extremely well. We’re satisfied customers!
Belinda Griego –
The set-up instructions that came with the water system were not clear, so I printed additional instructions from the website. Set up was easy once I had the additional instructions. I like the system; the water tastes good. I am happy to have purchased the Berkefeld water system.

Rick Totman –
I bought this for myself this past Christmas. I have been extremely pleased with the quality of water it puts out. Although we have good city water here, this Berkefeld water filter takes it to a whole new level. The water tastes clean and fresh. No taste, no after taste, just clean and pure. One of the best investments I have made for my home and health. My highest recommendation for anyone looking to do the same!
Victor –
Absolutely fantastic product. Nearly unlimited clean, fresh water everyday. I’m saving so much money not buying water anymore. Highly recommended, and fantastic customer service. 10/10

Very pleased with this product and spigot as well as their customer service.
The product was packaged extremely well and they were responsive and professional in answering my questions. Like that their Website is easy to navigate. Will be purchasing additional filters.

Our filter arrived quickly and had clear set up instructions. I got a quick response when I had a delivery address mixup. I received a phone call to clarify information, not just an email.
Jennifer Mullally –
Love it
Janna –
I’ve had a Berk for more than 20 years. I love the 100% reliability. Highly recommend. No moving parts just add water. I bought this one for my daughter
Brandon Corner –
This is the best water filter I have ever used. The stainless portion is no different than a Berkey, and getting the fluoride filters and stainless spigot, it was still a better price point that Berkey. I will say the first gallon or so seemed to have some dust from the filter. I just rinsed it out and refilled and it has been wonderful since!
Toby Wenning –
After a lithium battery warehouse exploded near us and contaminated the water killing fish we were woken up to the realization that there are a crap load of toxins in our water. Even if you didn’t have a lithium battery warehouse explode in your town, the amount of toxins that are in your water will shock you. We bought the Duke and are amazed how good the water tastes. I made my first pot of coffee using the filtered water and was amazed how good the coffee tasted. We give the water to our dog and cat because they deserve clean water too. It’s so easy to set up and it’s elegant looking in our kitchen. We figured that in the long run we will be saving money not having to buy bottled water. There are a lot of micro plastics in those bottles. Do it for your health! Easy to set up, not expensive, good looking and peace of mind.

Everything arrived and in good shape, I have not had time to set it up yet.
Marty –
My first Berkefeld purchase and I am pleased. Tanks and filters are exactly as advertised. No buyers remorse here!
Thoughts for the first time buyer –
1) the filtering rate is 1L per hour per filter which is to say “slow”. We have very good water quality in Oregon but the filtered water actually does taste a bit different and the chlorinated smell is gone.
2) the spigot sits 1/2″ above the counter so placement of the unit is an important consideration. There is a 5″ riser frame available but even with that, you won’t slide a 20 ounce tumbler underneath to fill. Make a plan for the clearance you need.
3) Get a viewing spout/spigot otherwise you will be lifting the top tank off periodically to learn the level in the bottom tank.
4) I would have preferred a brushed stainless finish option. Polished stainless is beautiful but also requires time spent removing finger prints with a soft cloth.
Curtis Harvey –
Purchased two units one for myself and one for my daughter. Very high quality. Considerable improvement in taste alone in my water.
Diana K. –
Love it! Wish I got the stand
Patricia Tamayo –
Perfect size for me! Still have questions about how long I can keep filters in the top of unit without Water covering them.
Ann Nobles –
Works as described.
Deborah –
I really like the way the water taste seems so much fresher, and I was convinced once I put the red dye in and the water came out clear, so the filters do their job.
Barbara O. –
Wow!! Love everything I order. Plus my two free gifts. Very high quality products. Love the taste of water. Great investment. I highly recommend the Berkeley
Marie P. –
Received quickly. Easy setup. I live in an area where water lines are old and constantly breaking. The duke berkefeld makes me feel confident that I am drinking good water. It works well when you are unable to install an under sink purifier.
Jodi Micka –

Dasha Patton –

George F. –
My 3rd berkefeld purchase in about 18 months 2 for my wife and me and one for my granddaughter
Brenda Park –
The only suggestion would be a prince window to see water level.
Pamela A. –
Love having your system. The directions were fairly clear although there were two different directions for prepping the purifier and one was definitely clearer than the other. Tried to use your chat pre-purchase and those on that day refused to reply to my question and wanted an email. Never had a chat where the communication wasn’t on the chat. Asked if I was ordering a first quality or scratch and dent. I received a filter with a dent. Was disappointed to see that. Not worth the hassle to send back though. Appreciate the stainless steel faucet and free water bottle

Excellent. The package was missing one little washer for the lid, but I can grab that for a few cents at a hardware store. Other than that, everything works lovely and was easy to set up.

Love our berkefeld . We just added fluoride filters. We didn’t know we needed those filters but glad we ordered them. They didn’t come with it. You have to order them separately.
William G. –
Easy set up and priming the filters. Water tastes amazing
Christine B. –
Great job everything was included that I had ordered:) I appreciate the prompt mailing of the items I had ordered. All I drink is water and so thankful of the clean taste of the berkefeld filtered water.
