Suitable for use in the British Berkefeld® Gravity water filter system, our Ultra Fluoride cartridge delivers all the expected benefits of a ceramic water filter candle, giving superior flow rates in a gravity filter while reducing particles, pathogenic bacteria and cysts. This Element has been tested to reduce up to 98.9%* of Fluoride and will adsorb a total 1,950 ppm of Fluoride - E.g. if your water contains 1ppm of Fluoride the Ultra Fluoride will effectively filter 1,950 Litres before needing to be replaced. Doulton® ceramic filter candles retain naturally-occurring minerals that make water taste great.
 
Replacement interval for the Pair is 3900L ( 2 x 1,950 each filter)
Please note these filters start of very slowly and the flow rate will increase to around 2L per hour
