Five steps to turn tap water into revitalised water

Filtration, information, optimisation, harmonisation, bioavailability

In nature, water undergoes a long process on its journey from the cloud to the spring. It seeps through layers of earth, flows over stones, comes into contact with minerals, is processed by microorganisms and finally finds its way to the light – clear, alive and full of energy. This process cannot be replicated in a single step. It requires several stages that build upon one another.

At MAUNAWAI, we have translated this natural journey into five principles. Each principle corresponds to a phase that water undergoes in nature – and which our filtration system replicates step by step.

Principle 1: Filtration

The first step is the most obvious: anything that doesn’t belong in the water must be removed. In nature, layers of earth, gravel and sand take on this task. In our filter systems, activated carbon from coconut shells and a high-quality ceramic membrane work together to remove pollutants in a targeted manner.

Activated carbon is at the heart of mechanical filtration. Just four grams of activated carbon has an internal surface area equivalent to a football pitch – around 6,400 square metres. Our cartridges contain 170 grams, which equates to an effective surface area of over 270,000 square metres. This enormous surface area enables the effective binding of contaminants such as heavy metals, pesticides, pharmaceutical residues, chlorine and trihalomethanes.

Importantly, the filtration process specifically removes pollutants whilst retaining the valuable minerals and trace elements in the water. This fundamentally distinguishes us from systems such as reverse osmosis, which remove everything – the bad as well as the good.

The results of independent analyses speak for themselves: heavy metals are reduced to below the limit of quantification. Chlorine disappears completely. Trihalomethanes are removed by 99.2%. Pesticides and polycyclic aromatic hydrocarbons are below the limit of detection after filtration. All this whilst calcium, magnesium and potassium are retained in the water.

Principle 2: Information

In nature, it is not enough simply to make water ‘clean’. Water flowing through natural rock layers comes into contact with hundreds of minerals. In doing so, it not only absorbs substances but is also shaped by its interaction with these minerals – it acquires specific characteristics, a kind of mineral fingerprint.

Our filter cartridges contain 21 different, highly porous mineral ceramics. Each of these ceramics has been fired at over 1,000 degrees Celsius – a complex process that permanently binds the natural properties of the minerals into the ceramic matrix. When water flows through these ceramics, it interacts with the minerals – much like in nature.

The materials used include, amongst others, noble shungite with its high fullerene content, zeolite granules, coral sand ceramics and various bio-ceramics. Each material fulfils a specific role in the overall process – and it is only through the interaction of all 21 ceramics that the special quality of MAUNAWAI water is created. This ceramic blend has been developed exclusively for MAUNAWAI and is not available from other manufacturers.

Principle 3: Optimisation

Natural spring water has certain physical and chemical properties: a slightly alkaline pH value, a specific redox potential, and a balanced mineral composition. Ordinary tap water often deviates from these values – not dramatically, but noticeably.

In this step, the mineral balance of the water is rebalanced. The coral sand in our ceramics acts as a natural cation exchanger: calcium, which has a higher binding affinity, displaces the magnesium attached to the ceramic matrix. This naturally increases the magnesium content of the water. At the same time, alkali metal ions such as potassium are exchanged for calcium ions in a ratio of 2:1.

The pH value is also shifted slightly towards the alkaline side in this step – to around pH 8.

 This corresponds to the pH value found in many natural spring waters. The redox potential is also slightly increased, and water hardness is reduced by 60–70%. The result is water whose chemical and physical properties are significantly closer to those of natural spring water than the original tap water.

Principle 4: Harmonisation

In nature, water does not flow in a straight line. It swirls, twists, flows over obstacles and through narrow crevices. This movement is not random – it influences the cluster structure of the water. Large, disordered molecular clusters are broken up, giving rise to smaller, more ordered structures.

In our filter cartridges, this swirling effect is deliberately created. The various ceramic layers are arranged in such a way that the water does not simply flow through, but turbulence is generated. In addition, tourmaline ceramic beads emit natural far-infrared radiation (FIR), which resonates with the water molecules. This process weakens the cohesion of large water clusters and promotes the formation of smaller, hexagonally ordered structures.

Principle 5: Bioavailability

The final step is also the most important: the water should not only be clean and rich in minerals, but also be optimally absorbed by your body. Bioavailability means: how well can your body utilise what is contained in the water?

Smaller water clusters have a larger effective surface area and lower viscosity. They can pass through the aquaporins – the water channels in your cell membranes – more easily. Independent studies by the IIREC Institute confirm that MAUNAWAI water exhibits properties similar to those of intracellular fluid after filtration: a distinct vital frequency of 22.5 Hz and resonance signals at 61.0 Hz, which are associated with cell membrane function.

This is also evident in practical terms: many of our customers report that MAUNAWAI water tastes softer, feels fresher and is better absorbed by the body. Some notice that they drink more – simply because the water tastes better. Others report improvements in skin condition, digestion or general well-being. These are personal experiences, not medical claims. But they show that bioavailability is not an abstract concept – it is tangible.

It’s the synergy that makes the difference

None of the five principles stands alone. It is the interaction of all stages that makes the difference. A pure activated carbon filter can filter, but not optimise. An ion exchanger can alter minerals, but not harmonise them. Only the combination of all five principles – in the right order, with the right materials – produces water whose properties closely resemble those of natural spring water.

Put simply: at the end of the filtration process, you have water that your body can not only drink, but actually utilise.
