Doulton Ultracarb Replacement Filter (To fit countertop system only)
Doulton Ultracarb Replacement Filter Suitable for use with Stainless Steel Countertop System Only
Replacement Doulton Supersterasyl Ceramic Filter
These genuine filters are made in England and will filter absolute to 0.9 microns.
These Premium filters needs to be replaced every 2300 litres of water filtered.
Higher levels of chlorine, chemical contamination, or sediment, will slightly shorten the life of the filters.
Recommended for use on town, tank or alternative water supply.
Silver impregnated ceramic walls makes these filters superior to other ceramic filters.
Laboratory Test results show these filters are very efficient at removing impurities such as chlorine, bacteria, amoebas, suspended solids, organic pesticides, some heavy metals, bad tastes and smells. They will remove 99.99% of Giardia and Cryptosporidium.

Doulton Filter History
You may associate the name of Royal Doulton with fine tableware and figurines, but do you know how they came to have the word "Royal" associated with their name?
As early as 1827, Henry Doulton developed a ceramic filter to remove bacteria from the contaminated Thames River, to provide safe drinking water. In 1835 Doulton made a gravity fed stoneware water system combined with the ceramic filter, for use by the royal household. By 1862 with the advancement in microbiology Doulton created micro porous ceramic filters capable of removing more than 99% of bacteria.
The tiny pores of the ceramic filter known as depth filtration, make it extremely efficient at removing particulate matter and fine sediment. The tightly packed activated carbon will remove taste, odours and unwanted impurities through a process called adsorption. The ceramic wall of this filter has been impregnated with silver ions to prevent the growth of bacteria in the filter itself and also in the stored water. (The silver is not painted on the inside of the walls like other filters and will not disperse into the filtered water or wear out in 6 months.) Since the beginning of the century Royal Doulton has been a leading name in water filtration, world renowned for high guality and reliability.
For their achievements made in water filtration, Doulton was given the right to use 'Royal' in their name in 1902.
How Activated Carbon Works to Filter Your Water
Activated carbon or AC, works by attracting and holding certain chemicals as water passes through it. AC is a highly porous material, therefore it has an extremely high surface area for contaminant adsorption.( Adsorption is the phenomenon whereby molecules adhere to a surface with which they come in contact with. When water containing soluble organic materials comes into contact with the granular activated carbon it selectively removes these materials by adsorption.)
AC is made of tiny clusters of carbon atoms stacked upon one another. The carbon source is a variety of materials such as peanut and coconut shells or coal. the raw carbon source is slowly heated in the absence of air to produce a high carbon material. The carbon is activated by passing oxidizing gases through the material at extremely high temperatures. The activation process produces the pores that result in such a high adsorptive rate.
