Filtration Stages

Stage 5 – Coconut Carbon Filter

Crafted from premium coconut shell carbon, this stage neutralizes acidity and removes any off-tastes or odors that develop in stored water, restoring a fresh, natural flavor.

Stage 6 – Mineral Enhancement Filter

Packed with volcanic rock and calcite media, this stage reduces water’s surface tension to inhibit bacterial and algal growth, while infusing the water with essential natural minerals for a balanced taste and added health benefits.

Stage 7 – Nano-Silver Disinfection Filter

Employs silver nanoparticles to deliver powerful antimicrobial protection, effectively eliminating bacteria and other harmful microorganisms for water that’s safe and hygienic.
