C-Series Radon in Water 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 backwashing control valve on top of a deep backwashing carbon tank, filled with the media matched to your water. The valve backwashes the bed on schedule to keep flow strong and the media working — no cartridges to change. 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 radon in water from your water
• Clean, chlorine-free taste and smell at every tap
• Gentler water for skin, hair and laundry
• Protects downstream softener resin and appliances
• Whole-house coverage, no cartridges to swap

Sized and matched to your water

Pick your home size above (1–3, 3–4 or 5–6 bathrooms) and we build it to your flow. Send a water test or your symptoms and we size it free. Ships free in the US with full install and service manuals. Need a matched multi-stage well package? See our same-brand C-Series well bundle.

Prefer a different valve brand? The same radon in water solution is available in Fleck, Autotrol, C-Series, Pentek and Pentair — the media doing the work is the same.
