British Berkefeld 7″ Ultra Fluoride Ceramic Water Filter
The British Berkefeld 7-inch Ultra Fluoride ceramic filter delivers powerful multi-stage filtration designed specifically for gravity water filter systems.
Each filter features a micro-porous ceramic outer shell that physically blocks bacteria, cysts, and sediment. Inside the filter, activated carbon and specialized fluoride-reduction media help reduce chemicals, heavy metals, and other contaminants while improving the taste and clarity of drinking water.
Ultra Fluoride filters are certified by NSF International to four drinking water standards, verifying their performance through rigorous third-party testing.
Unlike many gravity filtration systems that require separate fluoride add-on filters, this all-in-one design integrates multiple filtration stages into a single cartridge for simpler installation and maintenance.
These filters are ideal for home kitchens, emergency preparedness, off-grid living, camping, and everyday drinking water filtration.
NSF Certified Filtration
British Berkefeld Ultra Fluoride filters are certified by NSF International to four drinking water standards, confirming their performance for contaminant reduction and material safety.
✔ NSF/ANSI Standard 42 – Reduction of chlorine, taste, and odor
✔ NSF/ANSI Standard 53 – Certified for health effects contaminant reduction
✔ NSF/ANSI Standard 372 – Certified lead-free materials
✔ NSF/ANSI Standard 401 – Reduction of emerging contaminants such as lead Microplastics
These certifications confirm that the filters meet strict third-party testing standards for drinking water safety and filtration performance.

Designed for British Berkefeld Gravity Systems
The Ultra Fluoride ceramic filter is specifically designed for British Berkefeld gravity water filtration systems.
Unlike some gravity systems that require a main filter and a separate fluoride filter, this all-in-one cartridge performs both functions in a single filter.
This simplifies installation while still providing powerful contaminant reduction.
System Compatibility
The number of filters used depends on the gravity system size.
| System | Number of Filters |
|---|---|
| Baron Berkefeld | Not compatible — outdoor systems typically do not use fluoride filtration. |
| Duchess Berkefeld | 2 Filters |
| Duke Berkefeld | 2-4 Filters |
| Prince Berkefeld | 2-4 Filters |
| King Berkefeld | 2-8 Filters |
| Borosilicate Glass System | 2-4 Filters |
| Stoneware System | 2-4 Filters |
Using multiple filters can increase filtration speed and overall system capacity.
Gravity Water Filter Comparison
Many gravity filtration systems appear similar but use different filtration technologies.
| System | Filter Technology | Fluoride Reduction | Bacteria Filtration | Notes |
|---|---|---|---|---|
| British Berkefeld / Doulton | Ceramic + Carbon | ✔ | ✔ | Traditional ceramic filtration used worldwide |
| Berkey | Carbon block | Optional add-on | Limited | Popular stainless steel gravity system |
| Alexapure | Carbon composite | ✔ | Limited | Strong chemical reduction |
| Culligan Gravity Filters | Carbon | Some models | Limited | Large household brand |
Ceramic filtration remains popular because the micro-porous ceramic shell physically blocks bacteria and sediment, while activated carbon reduces chemicals and improves taste.
How Gravity Water Filters Work
Gravity water filters use two chambers.
1️⃣ Water is poured into the upper chamber
2️⃣ Gravity pulls water through the filter cartridges
3️⃣ Clean water collects in the lower chamber
Because gravity systems require no electricity, plumbing, or pressure, they are ideal for everyday drinking water, emergency preparedness, and off-grid living.
What’s Included
• 2 × British Berkefeld 7″ Ultra Fluoride Ceramic Filters
• Installation wing nuts and washers
✔ Ideal for gravity water filtration systems that require powerful contaminant reduction with fluoride filtration built directly into the filter cartridge.

Danielle M. –
I was a little nervous and helped pull some water through with the initial installation. I left the water filter overnight and then dumped it and added a sec full tank of water before work. When I got home I fulled in another tank that was for drinking. Smooth and clean smell. I really love the taste. The water filter filters like a dream. Living in an old apartment doesnt help water and this is amazing. Also it doesnt leave a deposit in my water kettle.

I have Rheumatoid Arthritis and these filters do not require the arduous priming that the black Berkey filters need. No stress on the hands. Water taste great. Loved that you came out with ones that get rid of the fluoride.
Jeffrey M. –
Love the filters… the taste is great! It’s the first time in a very long time I am fully confident in the quality of my water filters – I had questions about Berkey for a while, and am very glad I found Berkefeld.

These filters are the best. I have been using a gravity water filtration system for years. At one point, I was using a different brand of filter that was supposed to last for six months. The filters went bad after a week and a half. Tried twice but both times they didn’t work. Another filter literally fell apart in the upper chamber. I have been using British Berkefeld 7″ ceramic Ultra Fluoride for several years now. They last six months as promised and, since filtering out fluoride, I have noticed a difference in that my mouth and throat do not feel irritated. These filters can be used in any filtration system that matches the ones they sell. Plus the company site makes it easy to make purchases, and they are prompt with shipping. I also like that they offer accessories. I highly recommend these filters and this company. Thanks!

This Filter works great as a Berkey replacement. No priming, it was a little slow the first 3 or so fill ups but now is flowing well. Shipping was fast and arrived undamaged.
