Key Features & Benefits

13-Stage Filtration & Activation

The BIO 500 combines activated carbon, patented nano carbon compounds, bio-ceramics, mineral media, magnets, and alkalising components to purify and revitalise water using gravity-fed filtration.

Advanced Fluoride & PFAS Reduction

A patented nano carbon compound targets fluoride and PFAS (forever chemicals), with independent testing showing up to 99% reduction.

Alkaline Mineral Water

Filtered water typically reaches a pH between 7.6–8.5, with over 60 bio-organic trace minerals reintroduced for balanced hydration and improved taste.

Long-Life, Cost-Effective Filtration

Each filter set lasts up to 12,000 litres or 36 months, delivering purified water at around 3 cents per litre.

Simple, Non-Electric Design

The BIO 500 works entirely through gravity and requires no electricity, tap connection, or installation.
