Whole House Water Filtration System – 1.0 Cu Ft Catalytic Carbon, 9″x48″ (In/Out Valve)

$490.00

Right-sized for smaller households, this 1.0 cu ft catalytic carbon system handles the same chloramine, chlorine, and hydrogen sulfide reduction as our larger models — just scaled for 1–2 bathroom homes.

Coconut shell catalytic carbon, pre-loaded in a 9″x48″ tank, with a simple in/out valve. No electricity, no backwashing, no programming. If your water also has high iron or sulfur, pair it with a KDF 85 MediaGuard for added protection.

Description

Not every home needs a full-size whole house filtration system. If you’re in a smaller home, condo, or a 1–2 bathroom household, this 1.0 cu ft catalytic carbon system gives you the same real chloramine and chemical protection as our larger models — just sized appropriately, so you’re not paying for capacity you don’t need.

Why Catalytic Carbon (Not Standard Carbon)

Many water utilities have switched from chlorine to chloramine as a disinfectant because it’s more stable and produces fewer disinfection byproducts. The catch is that chloramine is genuinely harder to filter out — standard granular activated carbon has limited capacity for it. This system uses 12×40 mesh catalytic, high-activity granular activated carbon, made by steam-activating select coconut shell charcoal, specifically because it has a much stronger catalytic action than standard carbon. That catalytic property is what makes it effective against chloramine and hydrogen sulfide, not just chlorine and taste.

The large micropore volume of this carbon also targets low molecular weight organic compounds and their chlorinated byproducts — including chloroform and other trihalomethanes (THMs) — contaminants standard filters often miss entirely.

What This System Removes

  • Chloramines
  • Hydrogen sulfide (light to moderate loads)
  • Chlorine, tastes, and odors
  • Sediment
  • THMs and related organic compounds

For water with very high iron or sulfur content, pairing this system with a KDF 85 MediaGuard adds dedicated iron and hydrogen sulfide reduction alongside the catalytic carbon’s chloramine and chemical removal.

Simple In/Out Valve — No Backwashing Required

This system uses a straightforward in/out valve rather than an automatic backwash controller. Water flows in, passes through the 1.0 cu ft carbon bed, and flows out — no electricity, no drain line, nothing to program. It’s an inexpensive, low-maintenance setup that’s easy to install and easy to live with.
