Ceramic Filtration Process
In general, the smaller the pore size of a filter and the more complex the path the water takes through the filter medium, the more effective it is at removing particles from the water. Ceramic material has a small and intricate pore structure, making it an ideal filtration medium. The pore structure of Doulton® and British Berkefeld® ceramic drinking water filters is precisely controlled. This expertise gives the candles the necessary pore structure to filter a wide range of waterborne contaminants throughout the filter's lifespan. To understand the size of pores smaller than 1 micron, consider that the width of a human hair is 100 microns. Doulton® and British Berkefeld® water filters have been continuously manufactured in the UK for over 185 years. In the 19th century, the Thames River was London's primary water source, but it also served as a sewer. Henry Doulton® discovered that filtering water through porous ceramic could prevent people from contracting cholera and other waterborne diseases. Fairey Industrial Ceramics Limited (FICL) is the sole manufacturer of the world-renowned Doulton® and British Berkefeld® ceramic drinking water filters. All ceramic water filter products are manufactured at FICL's factory in North Staffordshire, England, the traditional hub of the British ceramics industry.
All stages of FICL’s drinking water filter production process comply with strict BS EN ISO 9001 quality standards. FICL's drinking water filters hold the highest international testing certifications, including NSF and WRAS.
Our high-quality standards are the reason why Doulton® and British Berkefeld® brands are globally sought-after in home water filtration systems.
The company named its first ceramic filter, developed 180 years ago, "Sterasyl," which mechanically cleaned particles from water down to 0.5 microns. Over the years, as water filtration needs evolved, this ceramic filter was technologically enhanced with silver ions, activated carbon granules (Super Sterasyl), heavy metal removal (Ultra Sterasyl), and fluoride removal (Ultra Fluoride Sterasyl) to meet modern demands.
