🌊 Product Overview

The LiquaGen 2.5” x 20” Strong Base Anion Filter Cartridge (Nitrate Reduction) is a high-capacity slimline cartridge designed to effectively reduce nitrates in drinking water, providing safer water for your entire family. Using strong base anion exchange resin, this cartridge preferentially removes nitrates even in the presence of competing ions like sulfates, delivering reliable performance in areas with elevated nitrate levels.

With its 2.5" x 20” slimline size, this cartridge offers twice the media volume of a 10” filter, providing extended service life and fewer replacements. It fits all standard 2.5” x 20” housings, making it ideal for under-sink systems, reverse osmosis add-on stages, or light whole-house setups.
