Doulton proudly supports the W3 Project and every purchase of a Doulton product benefits the W3 Charity Project.
The Doulton Imperial UltraCarb OBE Cartridge improves upon Doulton's Sterasyl ceramic cartridge, which is impregnated with silver that inhibits bacterial growth. In addition to this silver-impregnated ceramic, the UltraCarb also employs an activated carbon block which removes chlorine and organics, and an ion exchange resin insert that specifically removes lead from water.
The Imperial UltraCarb is an ideal filter for removing off-tastes and odors, particles, bacteria, cysts, chlorine, organics and lead. With the exception of Doulton's, this filter will fit in most standard size 10" housings.
Doulton's UltraCarb filters should be used in pressure filters on a main water supply, not in gravity filters. This genuine Doulton product is also known as part number W9223022.
