Our dual-action system combines premium activated carbon with powerfull redox media – outperforming carbon-only filters with better purification and longer filtration lifespans
Better Tasting Fridge Water & Ice
loaded with better, longer lasting filtration media
CUZN Filter's (by Waslix) next-generation filtration system overcomes the limitations of older powdered KDF sponge media by using heat- and pressure-bonded KDF-55 and KDF-85 spheres, ensuring long-lasting performance without degradation. This advanced KDF technology adsorbs chlorine, heavy metals (lead, mercury), iron, sulfur, and scale while providing antimicrobial protection.
The system also integrates Jacobi activated carbon—a premium filtration media, plus with bamboo carbon for superior contaminant removal and enhanced taste, outperforming conventional coconut carbon filters. The NMC series (NMC-III and NMC-IV) takes filtration further with multi-media synergy, combining KDF, catalytic carbon, and proprietary additives for 3x better chlorine removal, heavy metal reduction, and bacterial control.
NMC-IV adds self-adjusting redox technology, chloramine removal, scale inhibition, and improved flow rates—ideal for whole-house systems. With extended lifespan, minimal maintenance, and eco-friendly materials, CuZn Waslix delivers smarter, stronger, and more sustainable water purification than traditional single-media filters.
BILLIONS of micro pores across all our filtration media
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.
This filtration cartridge incorporates a blend of proprietary KDF media, Jacobi and bamboo activated carbon
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 Jacobi Activated Carbon (AC)
Our advanced filtration system combines premium Jacobi activated carbon with an exclusive bamboo carbon finish for unmatched water purity. The Jacobi media targets chlorine and a wide range of contaminants, while our proprietary bamboo carbon layer provides a final polish that conventional coconut carbon filters can't match. This innovative dual-stage approach delivers noticeably fresher, better-tasting water that sets 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.Includes Media 10x More Powerful Than KDF
Waslix's NMC series represents a revolution in water filtration, with NMC-IV building on the proven multi-media design of NMC-III to deliver even smarter purification. Both combine KDF redox media, advanced carbon (activated in NMC-III, catalytic in NMC-IV), and proprietary materials to tackle chlorine (3X better than standard carbon), heavy metals (lead/mercury), and bacterial growth—all in one compact unit. NMC-IV takes this further with self-adjusting redox potential for fluctuating contaminant levels, added protection against chloramines and scale, and enhanced flow rates. Unlike single-media filters, these engineered composites offer whole-house systems extended lifespan, consistent performance, and minimal maintenance—even in challenging water conditions.
Multi-Media Synergy
NMC-III: Combines KDF + activated carbon + proprietary materialsNMC-IV: Upgrades to catalytic carbon + enhanced KDF + specialized additives.
This targets a broader contaminant spectrum (chlorine, metals, organics, bacteria) than single-media filters.
Superior Contaminant Removal
3X better chlorine removal vs. standard carbonHeavy metal reduction (lead, mercury, iron) via redox reactions
NMC-IV adds:
Chloramine removal
Scale inhibition

Point Of Use (POU) Water Filtration Solutions
How long should your CUZN Water Filter last?
We cannot give you an absolute answer because water profiles vary between zip codes, seasons and from year-to-year.
If you were to compare our filters with another comparable size & structure, you will find our water filters realistically last 2-3 times longer because of our premium filtration media.
