✓ENHANCED HEAVY METAL REMOVAL WITH ZEOLITE — CERTIFIED: Our Zeolite Formula adds clinoptilolite zeolite to our original activated coconut charcoal filter, delivering enhanced removal of heavy metals including lead, arsenic, and cadmium. Certified under UNE 149101:2025 to remove up to 99% of PFAS, fluoride, chlorine, microplastics, nitrates, and more.
✓WHAT IS CLINOPTILOLITE ZEOLITE? A naturally occurring mineral with a honeycomb structure that traps heavy metals and toxins at a molecular level. Used in water purification, agriculture, and detox applications. Combined with our bioceramic technology and activated coconut charcoal, it delivers our most comprehensive filtration for tap water sources high in heavy metals.
✓NO SODIUM, HIGH ANTIOXIDANT POTENTIAL: Like all Alkanatur filters, the Zeolite Formula uses no ion exchange resin and never adds sodium. It alkalizes to pH 8.5-9.5 and generates antioxidant water with up to -350 ORP. Our CAM system delivers 77.7% of those antioxidants effectively to your body, far more than the ~10% efficiency of other methods. Studied independently at Vigo University, Spain.
