KDF55 Filter Media: 99.2 % Lead Removal & 98 % Chlorine Reduction in One “Golden Alloy”

1. The Hidden Killers in Tap Water  

- Heavy metals (lead, cadmium, mercury) corrode RO membranes and accumulate in the body.  

- Free chlorine creates unpleasant taste and cancer-risk by-products.  

- Bacteria, algae and scale shorten appliance life and increase maintenance costs.  

 

> Most filters only mask the problem; KDF55 attacks the root cause.

2. Introducing ZONE KDF55 — A Proven Copper-Zinc Alloy

Performance Metric	Industry Average	ZONE KDF55
Lead (Pb²⁺) removal	≥95 %	≥99.2 %
Free-chlorine reduction	≥90 %	≥98 %
Bacteriostatic rate	≥95 %	≥99.9 %

 

Data source: ZONE R&D Laboratory Q2 2024 Heavy-Metal Removal Report

 

Why it works:  

- 85 % Cu / 15 % Zn fused at 1 083 °C for atomic-level uniformity—no “green water” or zinc leaching.  

- Redox reaction converts soluble heavy metals into harmless precipitates and neutralizes chlorine instantly.

3. Four Real-World Applications That Cut Costs

Application	Pain Point	Result with KDF55
Domestic RO pre-filter	Chlorine destroys membranes	Membrane life extended 2–3×
Whole-house system	Rust & silt clog pipes	Redox potential prevents rust formation
Commercial espresso	Ca/Mg scaling	87 % scale reduction
Outdoor emergency	Bacteria & algae	99.9 % bacteriostatic for 72 h

 

- Case Study: US chain Caribou Coffee switched to ZONE KDF55 in 2023 and reduced cartridge costs by 32 % within 12 months.
