Doulton Imperial 7" Super Sterasyl Ceramic Water Filter

Best Use:

The Doulton Imperial 7" Super Sterasyl Ceramic Water Filter was designed to be used in gravity fed water filter systems such as the Doulton SS-2, Doulton SS-4, and British Berkefeld / Big Berkey gravity fed filter systems.

Note: The Imperial 7" super sterasyl filter has the exact same water filtering capabilities as the regular 7" super sterasyl element, with the exception that it is 3/4 inch larger in diameter, creating more ceramic surface area exposed to the water, allowing for approximately a 30% faster water filtration rate (8 gpd vs 5 gpd). Because there is also more media surface area in the granulated carbon core, there may also be a slight increase in the adsorption levels of chlorine, chemical and organics removal.

3-Stage Water Filtration

Sterasyl Outer Ceramic Shell- Microfilters >99.99% @ .5 microns filtering out sediment, algae, rust as well as bacteria and systs like e-coli, salmonella, cryptosporidium and giardia.
Silver Impregnated- Self Sterilizing, prevents bacteria mitosis
Granulated Carbon Core- Removes Chlorine, pesticides, herbicides and organics improving taste and odor
