Catalytic Carbon Backwashing Filters: Next-Level Chlorine & Odor Control Upgrade your brew water with catalytic carbon—aka cat carbon—automatic backwash systems. From 1-inch to 1-1/4-inch plumbing, 1 cubic foot up to 4 cubic feet of high-grade media, 1 1/4 up to 6cf.

This stuff crushes chlorine, chloramines, hydrogen sulfide, and tough organics way better than standard GAC. No more funky tastes or smells sneaking into your espresso shots or cold brew. Auto-timer valves (Clack, Fleck, whatever) handle backwashing—no babysitting.

Perfect pre-treatment for reverse osmosis—shields RO membranes from oxidants, boosts efficiency, keeps your final water crystal-clear and low-TDS for killer extraction. Go small for home roasters; scale to 1-1/4-inch for cafe volume, easy 30 GPM flow.

Why cat carbon rocks: Faster reaction, longer life, zero chemical aftertaste—your beans shine brighter.
