Duchess Berkefeld Gravity Water Filter System
The Duchess Berkefeld is the smallest system in the Berkefeld family, making it an excellent choice for individuals, couples, apartments, RVs, or smaller kitchens that want dependable gravity-fed water filtration in a compact design.
Despite its smaller size, the Duchess provides a steady supply of clean drinking water for everyday use. The system can provide as little as 1.5 gallons per day and up to 2.75 gallons per hour depending on how frequently it is filled, making it a practical solution for daily water consumption.
Each Duchess Berkefeld system includes two genuine British Berkefeld Ultrasterasyl ceramic filters, which use a micro-porous ceramic outer shell combined with activated carbon filtration. This design helps reduce bacteria, sediment, chlorine, and other common contaminants while improving the taste and clarity of drinking water.
Constructed from highly polished 304 food-grade stainless steel, the Duchess has a clean and durable design that fits comfortably on most kitchen counters. When fully assembled, the system stands 18 inches tall with a 7.5-inch diameter, while the chambers nest together for easy storage or transport.
If you are looking for a compact gravity water filtration system that delivers trusted ceramic filtration and great-tasting water without electricity or plumbing, the Duchess Berkefeld is a simple and reliable everyday solution.

Water Contaminants This System Helps Address

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.

This filter is a neat little device that’s perfect for 2 people. The water it produces tastes noticeably clean and fresh!!

I made two orders, both with two filters, both orders only sent one filter. I emailed and left phone messages. One order has confirmed the second filter is on its way. I have yet to hear if the 2nd order has a filter shipped yet. I love the product from a past purchase.
That’s how you did.

I’ve been using my Duchess for a week and it’s great. It’s just the right size for one person. The turn valve is so much easier to use than the push valve on another brand that I’ve used.

I was expecting for it to be larger than what it is, but it fits perfectly on my sideboard in the kitchen nook. Was fairly simple to put together and have been loving the fact I don’t have to haul in those heavy 5 gallon jugs anymore. Water tastes wonderful!!
Marsha –
Love it and was impressed with the quick delivery time

Fantastic. Water tastes great. Worth the money. It does drip slow but I just use an extra container to keep water in. I wish I had bought it sooner. And I made a mistake with my initial order and attempted to use the chat feature. No one responded in the chat but they emailed me the next day and had already corrected my mistake. I really appreciated that.

The stainless steel spigot cut open my fingers when I try to attach it to the unit. The machining wasn’t well done on the threads and not do you recommend using a tool when installing stainless steel spigot. Otherwise, I love filtration system

Really easy to set up, looks nice in the kitchen, feels good to reduce our interactions with plastics, i love the metal spout!

I’ve been using this filter for a little over a week & I’m so happy with it! The water tastes delicious & clean. It’s super easy to refill.
I will say the water takes a while to filter through so it’s smart to have a backup pitcher or 2 that you can fill up with the filtered water to ensure you don’t run out.

I can taste a huge difference! And love there’s no plastic. I’ve bought 2 already. One for the house and 1 for my mom. Plan on buying another for the camper!

Very pleased with the Duchess. Easy to set up. Good water capacity for making coffee, tea, and Sparkle water for two people on a daily basis. It fits nicely under the kitchen cabinets with the lid knob removed.

In the summer of 2025, huge sections of northern New England went into a prolonged severe or extreme drought (depending on where you lived), and wells everywhere were stressed or went dry. Ours stopped producing in mid-September, and we had to buy drinking water at the grocery. Eventually we realized we might be in this drought for a while, so we started looking at water filters. First we got on the internet and learned everything we could about how they work–there are a lot of companies out there, and no two filter systems are exactly alike–and soon decided that British Berkefeld appeared to the best quality by far.
Boy, are we glad! The Duchess is the smallest of the Berkefeld catalog, and turned out to be perfect for two people and a dog. Our well didn’t recover for eight months, but our new filter had no trouble keeping up with what we needed for drinking, cooking, and washing (but not laundry–we got used to taking that to a laundromat). The upper and lower drums are polished stainless steel—impervious to light, of course—and you just pour your unfiltered water into the upper drum, put the lid back on, and then listen to the water trickling through the two candle filters. We found that if you take the candles out periodically and rinse them off, the system will continue to operate quickly and efficiently.

I cannot use it right now. I need to to send me the correct screw for the lids knob. The screw is way too narrow and the treads don’t meet. The screw just spins and falls out.
