2-Cubic Foot Catalytic Carbon Filter

2 Cubic Foot Catalytic Carbon Chloramine Filter with Automatic Backwash Valve

Upgrade your home or business water quality with a high‑capacity 2‑cubic‑foot catalytic carbon filtration system, engineered specifically for chloramine removal, improved taste, and cleaner, safer water throughout your entire property.

This system uses premium catalytic carbon, a specialized form of activated carbon that doesn’t just adsorb contaminants—it chemically breaks down chloramines into harmless chloride and nitrogen through catalytic decomposition. This makes it dramatically more effective than standard carbon filters for modern municipal water supplies that increasingly rely on chloramine disinfectants.

Why Catalytic Carbon Matters

Standard activated carbon removes chlorine easily, but chloramine is far more stable and requires a catalytic reaction to break apart. Catalytic carbon provides the reactive sites needed to decompose chloramine molecules efficiently, even at higher flow rates.

Performance of a 2‑Cubic‑Foot System

A 2‑cubic‑foot tank provides significantly more contact time than cartridge filters, which is the key factor in chloramine removal. Chloramine reduction requires extended contact time—typically 6–8 minutes—for complete breakdown, far more than chlorine.

Smaller 10" filters provide only seconds of contact time, but a full‑size 2‑cu‑ft tank delivers substantially higher empty bed contact time (EBCT), allowing catalytic carbon to perform the reaction effectively.

Included in This System

2 Cubic Foot Tank Durable, corrosion‑resistant tank sized for whole‑house. One tank is ideal for 3GPM flow rate.
High‑Performance Catalytic Carbon Media (2 cubic feet) Specially modified carbon designed for chloramine decomposition, hydrogen sulfide reduction, and improved taste and odor.
Automatic Backwash Valve (Programmable) Set your preferred backwash intervals to maintain media performance, prevent channeling, and extend carbon life. We recommend backwash every 60 to 90 days depending on use rate and how sensitive you are.
 

Required Tank Volume (gallons) = Peak Flow Rate (GPM) × Minimum EBCT* (minutes)

For a typical home:

Peak flow rate: 10-12 GPM (shower + washing machine running simultaneously)
Minimum EBCT for chloramine: 6 minutes
Required tank volume: 60-72 gallons
*Empty Bed Contact Time (EBCT)

You therefore need up to 5 x Two Cubic Foot Tanks at that flow rate. You can do that or get a flow restrictor. Setting the flow to 3GPM will provide enough contact time with carbon media. Contact you plumber for catalytic carbon tank that fits your needs. It’s good to have them regenerate automatically.

 

At 3 gpm EBCT ≈  min

Above the 4 min minimum for catalytic carbon
You can reasonably expect very high reduction, often 90%+ in practice, sometimes more, depending on inlet level and media quality (this is an inference from EBCT guidelines, not a lab guarantee).
