K8 Demo That Will Change the Way You Think About Water
Frequently Asked Questions – K8
Here are the most common questions we get about the K8 — the gold standard in premium water ionizers trusted worldwide.
How does the K8 improve my health compared to bottled or filtered water?
The K8 produces water rich in molecular hydrogen and antioxidants with a negative ORP, helping reduce oxidative stress in the body. It also provides micro-clustered water molecules, which are absorbed faster for better hydration and recovery. Bottled and most filtered waters can still contain acidity, microplastics, and chemicals like PFAs, while lacking these benefits.
That’s why top sports teams, Jillian Michaels, Tom Brady, Tiger Woods, and even families like Bill Gates’ choose Kangen Water® — when the best recovery and hydration really matter.
Is there a difference between alkalized water and bottled alkaline water?
Yes, and it’s an important one. Most bottled “alkaline” waters raise pH artificially by adding chemicals like sodium bicarbonate or potassium bicarbonate. While this increases pH, these additives are not naturally occurring in the source water and can be harder for the body to process long term.
Kangen Water® is naturally alkalized through ionization, producing a stable alkaline pH alongside antioxidant-rich, hydrogen-infused water with smaller microclusters for effective hydration.
See the demo video above to understand why Kangen Water® outperforms bottled alkaline water in both health benefits and taste.
Not all alkaline waters are created equal — and your body knows the difference.
Is Kangen Water safe for children and pets?
Yes. Kangen Water® is safe and beneficial for the whole family — including kids and pets. You can even use neutral pH 7.0 water for baby formula and medications.
Can the K8 replace household cleaners?
Absolutely. With its range of pH waters, the K8 produces Strong Alkaline Water (11.5) that can cut grease and remove pesticides from produce, and Strong Acidic Water (2.5) that disinfects surfaces, cutting boards, and even wounds. Many users replace most chemical cleaners with these water types.
How difficult is it to install and maintain?
Installation is straightforward — the unit connects directly to your kitchen tap. The smart filter lasts for thousands of litres, and the K8 alerts you when it’s time for replacement. Monthly maintenance takes just 5–10 minutes using the E-clean system. No complicated upkeep is required.
Does it remove fluoride and chlorine?
Yes. The K8 filter removes chlorine, sediment, and odours, while retaining healthy minerals. If fluoride is present, high-quality pre-filters can be used alongside the K8 to ensure its removal — giving your family truly fluoride-free water at home.
What’s the lifespan of the machine?
With proper care, the K8 is built to last 20+ years. It also comes with a 5-year warranty for peace of mind.
Can I take it with me if I move?
Yes. The K8 is fully portable. Many families take it with them when they travel or move homes, and it can be adapted to different tap fittings worldwide.
