Product Details

Doulton fluoride reduction cartridge is designed to reduce unwanted fluoride in municipal water supplies, whether it be naturally-occurring or added to a safe level by water providers. The fluoride water treatment cartridge is for use in the first chamber of the Doulton DUO housing followed by the Doulton NSF UltraCarb (W9123053) in the second chamber to achieve great-tasting filtered drinking water. How often you replace the filter will depend on quality of water in your local area and filtration needs.
