How to Remove Fluoride from New Zealand (NZ) Tap Water

A short-sharp look at Fluoride removal and the best process for removing this from your drinking/cooking water.

Reverse Osmosis No.1

We'll jump startight to the king of filtration here. RO is hands down the healtiest method for removing Fluoride (and other contaminants). Removal rates are extremley high 92% + (providing its a quality built RO membrane). Our systems are above 97% removal rates tested and do not leach any unwanted bi-products.

The other most common method

Activated Alumina. This media can be effective at reducing Fluoride with ion exchange, however there is a major drawback with this method. This media is know for leaching aluminum into the "filtered" water. This is concerning as there are possible associations with neurodegenerative conditions.

Difficuilt To Remove

Fluoride is difficult to remove from water because it exists as a dissolved ion (F⁻), not a particle.

Most common filters (sediment, carbon, even many ceramic systems) are designed to trap particles, chlorine, or organic chemicals. Fluoride, however, is:

  • Extremely small at the molecular level
  • Fully dissolved and stable in water
  • Negatively charged, which keeps it evenly dispersed
  • Highly soluble, meaning it doesn’t clump or settle out

Because of this, it passes straight through standard carbon and basic filtration systems.

Fluoride isn’t “floating in the water” — it’s chemically integrated into it. That’s why only advanced filtration technologies can reliably remove it.
