The now-defunct CuZn Company originally pioneered an innovative filtration approach using Reticulated Media Sponges, where powdered KDF (a copper-zinc alloy- CuZn) was adhered to a synthetic sponge matrix. While revolutionary at the time, this second-generation technology suffered from a critical design flaw - the KDF powder would gradually detach during use, compromising filtration effectiveness. We've advanced beyond this limitation with our superior third-generation KDF technology. Our process heat- and pressure-bonds KDF-55 and KDF-85 into durable filtration balls with irregular microscopic pores, eliminating the rub-off problem entirely. This innovation provides maximum contaminant adsorption while delivering long-lasting, consistent performance without degradation over time.

Activated carbon is a cornerstone of water filtration, renowned for its ability to effectively remove a broad spectrum of impurities. At Waslix (CUZN Filter), we sought the highest-quality activated carbon—not only to deliver superior water purification but also to extend the lifespan of our drop-in filter cartridges, eliminating the need for annual replacements. That’s why we chose Jacobi, a globally trusted leader with over 25 years of excellence in producing premium activated carbon as our primary activated carbon media.

KDF: The Smarter Way to Purify Water

KDF technology revolutionizes water purification with its advanced copper-zinc alloy that electrochemically outperforms standard filters. Our KDF-85 adsorbs chlorine and heavy metals (lead/mercury), while KDF-55 tackles iron, sulfur, and scale. Silver-infused KDF adds antimicrobial protection against bacteria and algae. Unlike inferior powdered versions, our engineered media delivers lasting performance for cleaner, safer water—eliminating contaminants carbon filters miss while preventing scale and extending system life. KDF Spheres are an advanced water filtration upgrade.

Premium Catalytic Activated Carbon (AC)

Our advanced filtration system pairs Jacobi catalytic carbon—a premium media with superior chlorine and chloramine removal—with an exclusive bamboo carbon finish for unmatched purity. The macroporous structure targets a broad contaminant range (VOCs, heavy metals) while resisting attrition, and our bamboo layer adds a final polish for taste refinement that conventional coconut carbon can’t match. This dual-stage synergy delivers longer-lasting performance and noticeably fresher water, setting our system apart.

Bamboo Improves Taste

While bamboo activated carbon is an unconventional choice in water filtration, our research proves its remarkable ability to enhance water quality. Though often dismissed due to its macroporous structure, this sustainable media delivers unexpected performance - particularly in taste refinement. As an eco-friendly alternative to traditional carbon sources, bamboo offers a unique combination of environmental benefits and water-polishing capabilities that conventional filters simply can't match.
