Fluoride Water Filter Replacement – 9″ x 2.5″ Eco

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. Made in Taiwan and an economical alternative to the Omnipure XF834.

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.

Please Note: when changing the fluoride cartridge it is important that the fluoride cartridge is flushed alone to prevent it from flushing into the next stages of filtration.  Flush water through this cartridge in the system for 10-15 minutes before adding the next stages. View Instructions.
