C-Series Nitrate & Nitrite (Well) Filter

The C-Series system that solves it

This is a full C-Series system built on three parts that work together: a C-Series metered control valve on top of a specialty ion-exchange tank, filled with the media matched to your water. The valve meters your actual water use and regenerates only when needed, so it never wastes salt or water. One consistent C-Series platform means parts and service stay simple for the life of the system — fully serviceable, never a sealed throwaway unit.

What it does for your home

• Removes nitrate & nitrite from your water
• Targets and removes the specific contaminant
• Consistent capacity between regenerations
• Whole-home protection at every tap
• Serviceable, refillable media — never a sealed box

Prefer a different valve brand? The same nitrate & nitrite (well) solution is available in Fleck, Autotrol, C-Series, Pentek and Pentair — the media doing the work is the same.
