🌊 Product Overview
The LiquaGen 4.5” x 20” Nitrate Removal Filter Cartridge is a whole-house solution for nitrate contamination, designed for use in Big Blue 20” filter housings. Packed with strong base anion exchange resin in chloride form, it selectively removes nitrates even when competing ions like sulfates are present, delivering reliable performance and safer water for every tap in your home.
Nitrates are a common problem in rural and agricultural areas, where levels often exceed the EPA’s recommended limit of 10 mg/L. Elevated nitrate exposure is especially dangerous for newborns, who may develop Blue Baby Syndrome, a potentially life-threatening condition. This large-capacity cartridge provides extended service life, protecting families, plumbing, and even aquariums from harmful nitrate levels.
