Ceramic filter operation
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 separating particles from the water. The ceramic material has a small and complex pore structure, making it an ideal filter 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 life. To understand the size of pores smaller than 1 micron, it is enough to know that the width of 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 River Thames was not only London's main water source but also served as a sewer. Henry Doulton® discovered that filtering water through porous ceramic could prevent people from falling ill from cholera and other waterborne diseases. Fairey Industrial Ceramics Limited (FICL) is the sole manufacturer of the world-famous Doulton® and British Berkefeld® ceramic drinking water filters. All ceramic water filter products are manufactured at FICL's factory in North Staffordshire, the traditional ceramics area of the UK ceramic 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 standards, NSF and WRAS certifications.
Our high-quality standards are why Doulton® and British Berkefeld® brands are sought after worldwide in domestic water filtration systems.
The company named the first ceramic filter, which mechanically cleaned particles up to 0.5 microns in water with a simple ceramic filter 180 years ago, Sterasyl. Over the years, as our water filtration needs have changed, this ceramic filter has been technologically enhanced with the addition of silver ions, activated carbon granules (Super Sterasyl), heavy metal (Ultra Sterasyl), and fluoride (Ultra Flouride Sterasyl) cleaning features, adapting to today's needs.
