Twin Water Filter Fluoride Removal Replacement Filter Set

The Doulton® Ultracarb water filter utilises a three-stage filtration process to purify water.  This water filter cartridge is suitable for the following systems:
Doulton Single Countertop Water Filter
Doulton Twin Countertop Water Filter
Doulton Under Sink Water Filter
Doulton Twin Under Sink with Fluoride Removal

Outer Ceramic Shell:

• Manufactured from proprietary Sterasyl® ceramic material with submicron pores that mechanically trap particulates, sediment, bacteria, cysts, and turbidity through size exclusion.
• Incorporates trace levels of silver that act as a bacteriostatic agent to inhibit bacterial growth within the shell.

Inner Filtration Core:

• Contains highly adsorbent, activated carbon made from NSF-certified coconut shells to reduce chlorine, organic compounds, and improve taste/odor.
• Also includes ion exchange resin beads designed to attract, bind, and remove dissolved heavy metals like lead and zinc.

Ion Exchange Resin: 

• Heavy metal removal media for the reduction of lead and other heavy metals.

By combining filtration in the outer shell with filtration in the inner core, this candle filter provides extensive removal of particulates, pathogens, chlorine, organics, and heavy metals for optimized water quality and safety.

Fluoride filter cartridge (9 Inch) suitable for both Doulton Twin Countertop Water Filter with fluoride removal and the Doulton Twin Under Sink Water Filter with Fluoride removal.

The Activated Alumina Cartridge utilizes a highly porous filter media to selectively adsorb fluoride ions, resulting in effective fluoride reduction from water sources.

The fine-mesh Activated Alumina contains an abundance of micro-pores with a high surface area. As water passes through, fluoride ions are drawn to and attach to the porous media's oxidized surface sites through a chemical/physical adsorption process.

Each pore and surface site acts as an adsorption point to capture free fluoride ions, systematically removing them from the water. This process leads to thorough fluoride reduction of up to 99.9%.

Through the selective adsorption capacities of the Activated Alumina, the cartridge provides an efficient method for decreasing concerning levels of fluoride often present in public water supplies. The media chemically attracts and binds the fluoride ions to deliver water with significantly reduced fluoride content.
