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 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 | 1 Filter |
| 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 increases filtration speed and total system capacity.
Gravity Water Filter Comparison
Many gravity filtration systems appear similar but use different filtration technologies.
| System | Filter Technology | Fluoride Reduction | Bacteria Filtration |
|---|---|---|---|
| British Berkefeld / Doulton | Ceramic + Carbon | ✔ | ✔ |
| Berkey | Carbon block | Optional add-on | Limited |
| Alexapure | Carbon composite | ✔ | Limited |
| Culligan Gravity Filters | Carbon | Some models | Limited |
Ceramic filtration remains popular because the micro-porous ceramic shell physically blocks bacteria and sediment, while carbon media improves taste and reduces chemicals.

We used these filters to replace filters of a different brand. We found these to be fully compatible and easy to install. Plus the water tastes much better!

I was so excited to find an all in one filter! As soon as it arrived I but them to work! Best decision ever! Water tastes amazing! Thank you for this amazing clean product! Now I can have clean fully filtered water when I travel in my travel gravity system!

I bought the Fluoride filter for the safety of my grandson. But after installing it yesterday, I was truly amazed at its high flow rate. This is no doubt due to its much large volume compared to the standard filters. The whole family is thrilled with how quickly filtered water is now available for use compared to the standard filter.

Your product is exceptional just like your customer service.

I love these filters and the fact I do not have plastic in my clean water reservoir. I also love that I was able to sign up to have them auto shipped so I never need to worry about having clean water. The water is absolutely fantastic and has no after taste at all. It just really refreshing !!!

I love this filter because of its reduction/removal of flouride
Hope T. –
Product is great, it takes two filters even for a small unit. I feel the pricing is high, especially when you have to buy 2 and their only good for 6 months. But I feel it’s the best filter on the market.

The Ultra Fluoride filters are fantastic. We knew it was time to change our Berkey filters but could not find any in stock due to the legal issues that Berkey is facing. Don’t get me wrong, the Berkey filters were great and served our family well, but our water tastes much better after using these filters from British Berkefeld. We would highly recommend these filters to anyone and have already done so to friends in the same situation as we were. I would also like to point out that from the time of purchase to delivery was very quick. Britishwaterfilter.com has won us over as a customer.

All the good: Taste great. Easy to install in existing berkey tower. Customer service was quick to respond to simple email and questions.
Bad: not really bad just expect a long filtering time. 2 filters take about 8-10 hrs to filter 6 gallons (mind you it is filtering pre treated tap water). Would reccomend highly getting the fill reading spigot and possibly running 4 filters. Cutts time down significantly.
Madeline M Rice –
So glad to have a reliable source for replacement filters. The price, quality and fast service is impressive. Thank you!

I have a Berkey unit, and this has been my first experience with the British Berkefeld company. From the customer rep’s friendly help in ordering the fluoride filters I needed, the fast arrival of the filters that I ordered to fit my size Berkey, to the ease of installation (versus the Berkey filters — there is NO priming of these filters, and that is HUGE, at least for me!), this has been a great experience. I look forward to ordering more filters from this company in six months. Safe drinking, fellow water consumers!

so glad we can still get these important filters!
Mary N. –
Love that nothing is hanging in the water reservoir. Genius! Be patient. Reserve some water for use and allow 24-48 hours to run 3 full tanks through the new filters. Then enjoy….
Norma Sparso –
excellent product- easy to insert, water taste great, excellent customer service

IT TOOK A LITTLE LONGER TO PRIME BUT IS WORKING JUST FINE IN MY BERKEY!
