Doulton British Berkefeld Ultra Fluoride Ceramic Filter Candle

Replacing the Durand Stoneware Doulton Sub Micron Ceramic Water Filter with silver ions...

Introducing advanced British Berkefeld (Doulton) Ultra Fluoride Filter, the superior next generation for our SCP Fluoride Plus™ filter. Engineered to effectively remove fluoride and a wide array of other contaminants, this filter ensures your drinking water is safe and free from harmful substances. Made from durable, food-grade materials and NSF certified, it represents the premium quality and reliability you expect from the Doulton brand.

The Ultra Fluoride Filter, stands 146mm high (5 3/4 inch) and has been specially manufactured by Doulton for Southern Cross Pottery distribution. Unlike the current ultra fluoride candle marketed in Australia, which is 178mm tall and too large for most gravity systems, this filter is designed to fit perfectly. It is compatible with all purifiers made by Southern Cross Pottery and most other brands of gravity filtration systems, including Earthtank, Village Pottery Company, Sean Nicholson Clay, Durand, Waterco, Australis, Stefani, Pozzani, Peter Wallace Pottery, and Filteroo.

More Information: 

Rigorously Tested: Proven to remove up to 98.9% of fluoride, absorbing a total of 1600 ppm. For water with 1 ppm of fluoride, the filter effectively purifies 1600 litres before replacement. With fluoride levels below 1 ppm, it can purify even more. Australia's municipal fluoride average ranges from 0.6 to 1.1 ppm.

Broad Spectrum Contaminant Removal: Eliminates up to 99.99% of common contaminants, including fluoride, bacteria, chlorine, parasites, microplastics, trace organics, enhanced organics, pharmaceuticals, arsenic, and heavy metals like lead.

Natural Raw Materials: Made from 100% naturally occurring raw materials, these vegan-friendly filters contain no activated alumina or bone ash.

Taste Preservation: Maintains essential minerals like calcium, magnesium, and potassium, enhancing water taste and slightly increasing alkalinity for a healthier pH balance.

Replacement Intervals: For optimal performance, replace the ultra fluoride filter every 1600 litres or every 6 to 9 months, whichever comes first. To ensure continuous contaminant removal, it is highly recommended to replace the filter every 6 months. 

Other Key Points:

1. Ideal for use with municipal town water, tank water, and bore water.
2. Flow rate under gravity is approximately 900 ML per hour.
3. Absolute filtration down to 0.2 microns.
4. Manufactured by Fairey Industrial Ceramic Laboratory (Doulton) in England.
5. No need to sterilise or boil water, as the Doulton® proprietary system inhibits microbiological growth.
6. The small amount of plastic used in the candle frame is BPA-free.
7. Each ultra fluoride candle has a unique 10-digit code on the filter frame, guaranteeing authenticity.

FILTRATION SPEED - The new Doulton Ultra Fluoride filter can purify approximately 900 ml per hour of water.  The Ultra Fluoride filter is a vastly superior filter in terms of impurities removed and effectiveness over time BUT has a slower flow rate than its predecessor for two key reasons:

1. The Doulton filter does not use hot melt to secure the ceramic filter to the plastic housing. When hot melt is used, water can seep around the ceramic and the mount, allowing faster flow, but this means not all water passes through the filtration system. With the Doulton Ultra Fluoride, all water is forced through the filter, ensuring thorough filtration.
2. Doulton does not use bone char as the primary filtering media, which typically offers little resistance to water flow. Instead, Doulton’s design includes a much thicker ceramic shell, a solid carbon block inside the ceramic, and loose media—all of which create more resistance and result in a slower flow. The ultra fluoride filters down to 0.2 micron, previous filter 0.9.

Because of  the slower flow, the outcome is significantly better; , more impurities are removed and unlike the previous filter the Ultra Fluoride maintains its effectiveness throughout its lifespan.
