Doulton has been making ceramic water filters, in the UK, for over 185 years. Ceramic is made from natural materials; 80% less plastic waste than other available synthetic cartridge filters. Only for a mains pressure supply. 

During use, contaminants filtered from the water may build up on the outer surface of the ceramic cartridge and cause a reduction in flow through the unit. The cartridge will, therefore, need removing periodically for cleaning to restore the flow.

Cleaning frequency will be dependent on the condition of the incoming water. A cartridge that has reached the end of its life would be indicated by a reduction in the quality of the filtered water with respect to taste. The cartridge should be replaced in accordance with the rated service capacity, which would typically give a period of six months usage. 6 months BPA free Long Life ceramic.

PLEASE NOTE:  the Ultracarb SI is not compatible with Franke Systems.
