The British Berkefeld® Ultra Fluoride Ceramic Filter is a premium all-in-one ceramic gravity water filter, manufactured in the United Kingdom by British Berkefeld (Doulton UK) — a world-renowned filtration company hand-crafting ceramic filters since 1862.
Designed for single-stage fluoride removal, this gravity-fed filter requires no priming, no electricity, and no plumbing, making it ideal for off-grid use, home gravity systems, travel, and emergency water filtration. Importantly, it retains healthy, naturally occurring minerals while reducing harmful contaminants.
Trusted British Manufacturing
The British Berkefeld® Ultra Fluoride Ceramic Filter is manufactured by one of the most credible water filter manufacturers in the world. British Berkefeld is known not only for exceptional build quality, but also for its rigorous, transparent testing regime, delivering credible test data and consistently excellent results.
Universal Gravity System Compatibility
These ceramic filter cartridges are suitable for almost any water type. Available in 5.75-inch and 7-inch sizes, there is an option to fit seamlessly into most gravity water filter systems.
Proven Gravity Filtration Performance
The slow, drip-by-drip gravity filtration process allows sufficient contact time between water and the filtration media. This ensures effective reduction of particles, pathogenic bacteria, and cysts, while maintaining excellent water taste.
The British Berkefeld® Ultra Fluoride Ceramic Filter has been tested to reduce up to 98.9% of fluoride, with a total adsorption capacity of 1,950 ppm.
*Tested in-house by Doulton® using a nominal influent fluoride concentration of 1 ppm.
