How a Water Ionizer Works

On the surface, water ionizers can often seem to be highly complicated. However, the science behind how they work is surprisingly simple and useful to understand.

Pre-filtration how a water ionizer works
Stage 1: Pre-Filtration

In a vast majority of water ionizers, at least those made by reputable brands, water is initially run through a filter when it enters the machine. This ensures that it is free from any unwanted chemicals and contaminants that could otherwise interfere with or reduce the efficacy of the ionization process.
Electrolysis how a water ionizer works
Stage 2: Electrolysis

Once the water has been filtered, it then passes through a set of electrode plates and membranes. These plates are charged with electricity, allowing them to electrolise the water molecules as they pass over, breaking them up into OH- and H+ ions along with any minerals found within the supply.
