Water Cooler Filters

Ceramic Filtration from The Waterpoint

The Waterpoint use, as standard, 0.9 micron Doulton Supercarb ceramic carbon block filters in all our water coolers. These filters are proven to remove a vast array of water borne contaminants including cryptosporidium, e-coli and giardia. They also reduce sediment and the cause of poor tastes and odours, dramatically improving the taste of the water produced by our water coolers. We replace these filters every 6 months to maintain the quality and purity of the water you will be drinking.
Water Cooler Filters
Doulton ceramic filter elements are manufactured under International Standards Organisation (ISO) conditions. They have the highly consistent and controlled pore structure necessary to provide genuine sub micron filtration. As the manufacturer of the Doulton Supercarb filter, Fairey Industrial Ceramics Limited (FICL) takes it's product performance claims very seriously. Where drinking water filters are concerned, it is of vital importance that manufacturers' claims as to the effectiveness of their products at removing contaminants are fully supported by proven test data.

All FICL's major claims with regard to the performance their filter elements and systems have been verified by independent laboratory testing.

Reasons to use a Ceramic Filter

Ceramics started to become widely used for the filtration of drinking water in the 19th century. At that time, cholera outbreaks were a common occurrence in London. Doulton & Co., with their factory on the banks of the River Thames, were in the perfect position to join the fight against water-borne disease.

In general, the smaller the pore size of a filter and the more complicated the path the water takes through the filter medium, the more effective it is at removing particles from water. A ceramic has a small and complex pore structure, making it an ideal filter medium. Doulton drinking water filters have been so successful globally because they have a variety of advantages over other products in the market:

Highly effective barrier to particles and pathogens: Doulton drinking water filters have a pore structure which has an Absolute filtration rating (defined as >99.99%) of 0.9 microns (less than 1000 th of a millimetre). Therefore, the ceramic is capable of removing sub micron particles and pathogenic bacteria from drinking water.

A recent study by a leading UK University showed that use of Doulton drinking water filters in a community in Zimbabwe slashed cases of potentially fatal diarrhoea (a common problem in Africa caused by pathogenic bacteria and cysts in the water supply) to virtually zero. These water filters have been proven to work in the most demanding conditions. This is why they are used by the major aid organisations.

Long life: As confirmed by the user instructions supplied with the product, Doulton ceramic drinking water filters may be cleaned in order to prolong the life of the product. In this way, the filter can be re-used rather than replaced, giving it a much longer life-span than many other products on the market. On average, a Doulton filter candle will remain effective for up to 6 months (depending on usage and water quality) before it will need to be replaced.

Self-sterilising: Doulton ceramics contain trace elements of silver. Silver inhibits microbiological growth, meaning that there is no need to sterilise, even when they are used over an extended period.

Natural: Doulton ceramics are made from 100% natural elements. They do not add anything to the water they filter. This contributes to their ability to pass the stringent NSF® testing procedures. Many other filter products add traces of chemicals to the water they filter.

Combinations with other filter media possible: Other filter media can be put inside Doulton ceramic drinking water candles to make them even more versatile. For example, activated carbon can be incorporated to remove chlorine, or an ion exchange resin to remove heavy metals such as lead.

Minerals maintained: Using a Doulton ceramic drinking water filter does not remove those minerals from the water, which are beneficial to health.

No power required: Doulton ceramic drinking water filters are some of the most versatile water treatment devices available today. They do not require electricity to function, which means that they are not vulnerable to interruption of power supplies, and can be used where there are no power supplies. They can be used literally anywhere in the world from an office block to a refugee camp.
