10 Reasons People Choose Alkaline Water — And What the Evidence Says

Alkaline water has attracted a lot of interest in Australia. Here are 10 reasons people choose it — with an honest assessment of what the evidence actually supports.

Browse our 8-stage KDF filter range (which produces mildly alkaline water) or see our Benchtop Water Filters Guide.

What Is Alkaline Water?

Alkaline water has a pH above 7 (neutral). Our 8-stage KDF filter systems include mineral stone stages that release calcium, magnesium, and trace minerals, raising the water’s pH to approximately 8–9 naturally. This is different from electric ionisers that use electrolysis.

10 Reasons People Choose Alkaline Water

1. Better taste. Many people find mildly alkaline, mineralised water tastes smoother and cleaner than chlorinated tap water. This is well-supported by user experience.
2. Chlorine removal. Our 8-stage systems remove chlorine through activated carbon — the main reason Australian tap water tastes off.
3. Heavy metal removal. KDF media removes lead, mercury, and copper — a genuine, evidence-based benefit.
4. Mineral content. Calcium and magnesium added by mineral stone stages contribute to daily mineral intake.
5. Bacteria removal. The ceramic stage removes bacteria and protozoa — a meaningful benefit for households on bore or tank water.
6. Eco-friendly. Filtered alkaline water eliminates single-use plastic bottles — a clear environmental benefit.
7. Cost savings. Filtered water costs a fraction of a cent per litre vs $1–3+ for bottled alkaline water.
8. Hydration. Better-tasting water means people drink more of it — which supports hydration, energy, and concentration.
9. Anti-ageing and cancer prevention claims. These are widely cited but not supported by robust clinical evidence. We don’t make these claims.
10. Athletic recovery. Some small studies suggest hydrogen-rich water may reduce oxidative stress after exercise. Evidence is preliminary and not conclusive.
