ZONE Selenium Mineral Ball

1. Why Your RO Water Isn’t “Healthy” Enough  

Reverse osmosis (RO) systems are excellent at removing contaminants — but they also strip away beneficial minerals like selenium (Se) and strontium (Sr). Long-term consumption of demineralized water can lead to:  

- Mineral deficiency (WHO reports 10–20% of daily mineral intake comes from water)  

- Poor taste and reduced beverage quality  

- Potential health imbalances  

 

** The solution? Remineralize your RO water with functional filter media — like ZONE Selenium Mineral Balls.

 

 

2. What Makes ZONE Selenium Balls Different?  

Unlike basic calcite or maifan stone, ZONE’s Selenium Ion Balls are engineered for controlled mineral release, long service life, and safety.

 

✅ Key Features:

- Metered Release: Maintains 8–12 µg/L Se and ≥0.2 mg/L Sr over 3,000 L  

- Long-Lasting: 0.5 L cartridge lasts up to 5.5 years for a family of 3  

- Safe & Certified: Heavy metals not detected (SGS tested)  

- No Scaling: TDS increase only 8–12 ppm — safe for instant heaters
