Three litres per person, every day. How much of that is actually clean?

A family of four drinks, cooks and uses around twelve litres of water every day. That adds up to over 4,000 litres a year, all from the tap. And this is where it becomes relevant: even well-regulated tap water can contain residues that no water treatment plant can remove completely. PFAS, traces of medicines, pesticides and hormones pass through the treatment process in concentrations that, whilst legal, are not acceptable to everyone.

In areas with hard water, there is another issue to consider: limescale deposits alter the taste, damage appliances and undermine confidence in water quality. If you want consistently clean, soft water for your family, you need a system that works reliably all day long.

The PiPrime K8 was designed precisely for this purpose: a 12-litre capacity, a full year’s worth of filtration, and water inspired by nature.

A family of four is gathered in a cozy kitchen, enjoying a meal together with a water dispenser prominently placed on the counter.

PiPrime: The 5-stage filtration process

Each of the five stages fulfils a specific function. Together, they produce water that is not only free from pollutants but also has a revitalised, living structure, comparable to natural spring water. And it works without electricity, without chemicals, and without a water connection.

Stufe 1

Ceramic filter. The first line of defence.

The ceramic filter is the first stage of the process. It is the preliminary stage through which your tap water passes before the actual purification process begins.

With its extremely fine pores, the ceramic filter physically filters out anything that doesn’t belong in your drinking water: particles, scale and other residues from the water pipes.

Stufe 2

Lime filtration. Reduces lime and heavy metals.

In the second stage, the water passes through the limescale filter pad. Here, specific problematic substances are removed from the water, including excess limescale and heavy metals.

It is particularly important to note that heavy metals such as lead or copper can enter the drinking water via old domestic plumbing. The limescale filter pad reliably reduces these contaminants.

The PiPrime K8 is fitted with limescale filter pads that are specially optimised for hard water (from approx. 14 °dH) and significantly reduce limescale.

Stufe 3

Activated carbon. The heart of the filtration process.

The multi-layer filter cartridge containing high-performance activated carbon is at the heart of the MAUNAWAI system. It traps organic pollutants that could not be removed in the previous stages.

A key advantage: the flow rate in the MAUNAWAI is deliberately slower than in many other systems. This significantly increases the contact time between the water and the activated carbon, thereby substantially improving the filter’s performance. The material: activated carbon made from coconut shells

MAUNAWAI K8 filter cartridge; the middle stage is visually highlighted

Stufe 4

Mineral ceramics. Just like in nature.

It is at this stage that MAUNAWAI begins to set itself apart from conventional filters: the purified water is revitalised. Zeolites, quartz and coral sand, as well as tourmaline ceramics, restore trace elements and the water’s natural structure, much like in a natural stream.

This process goes beyond simple filtration: the mineral ceramics enrich the water with trace elements and restore its natural cluster structure.

MAUNAWAI uses a proprietary blend of over 20 different highly porous mineral ceramics. The main components are:

Zeolite granules

Zeolites are highly porous natural minerals with an exceptionally large internal surface area. They act as natural biocatalysts: they absorb residual substances, facilitate ion exchange and promote the uptake of minerals by the water. In nature, zeolites are found in volcanic rock. They have been involved in the natural purification of water for thousands of years.

Quartz and coral sand ceramics

Coral sand is a natural cation exchanger. Calcium has a higher binding affinity than magnesium, which is why magnesium is displaced from the ceramic matrix and enters the water. This process increases the magnesium content. Potassium ions are exchanged for calcium in a ratio of 2:1. Quartz sand creates natural eddies that have a positive effect on the water structure, similar to a stony stream.

Precious shungite

A rare carbon matrix with a carbon content of 95–98% and a high concentration of fullerenes (C₆₀), spherical molecules composed of 60 carbon atoms. The 1996 Nobel Prize in Chemistry was awarded for research into fullerenes (Curl, Kroto, Smalley). The properties of precious shungite in water: Catalytic: Promotes the oxidation of active chemical compounds Antioxidant: Binds free radicals Supportive: The ceramic matrix counteracts the growth of microorganisms Structuring: Supports the reduction of water clusters, as smaller water clusters are more easily absorbed by the body Preservative: Shungite water has been proven to stay fresh for longer

Tourmaline ceramic beads

Tourmaline continuously emits natural far-infrared radiation (FIR) in the wavelength range from 5.6 µm to 1,000 µm, the biologically relevant range for the human body. This long-wave radiation resonates with water molecules and causes: Cluster reduction: Large, disordered molecular clusters are broken down Structuring: Formation of smaller, ordered hexagonal water structures Cell permeability: Smaller water clusters pass through cell membranes more easily

Other ceramics in the mixture

EM ceramics (Effective Microorganisms) Calcium ceramics Bio-ceramics (FIR principle) Antibacterial ceramics Alkali ceramics

MAUNAWAI K8 filter cartridge; the bottom stage is visually highlighted

Stufe 5

Pi technology. Living water.

In the final stage, EM ceramics and calcium complete the regeneration process. The pH stabilises in the slightly alkaline range, and the water’s natural cluster structure is fully restored.

At the end of this process, your water will have properties that make it comparable to natural spring water: a revitalised structure, a balanced mineral content and a taste that you will notice straight away.

Cluster reduction

Tap water forms large, disordered molecular clusters. The combination of tourmaline FIR radiation, precious shungite fullerenes and mineral ceramics breaks these clusters down and reorganises them into smaller, more ordered structures known as hexagonal clusters.

Hexagonal geometry

Laboratory analyses show that MAUNAWAI water has a hexagonal structure. This hexagonal structure is associated with regenerative properties. This is characteristic of high-quality spring water.

Evaporation images

In standardised evaporation tests, MAUNAWAI water exhibits concentric rings, crystal-like structures and a high degree of coherence (order). These are characteristics that indicate an intact, living water structure.

pH level

Approx. pH 8 (slightly alkaline). Corresponds to natural spring water.

redox potential

227–252 mV. Indicates the release of reducing substances.

coherence frequency

22.5 Hz (circularly polarised). Associated with optimal water absorption by the body.

Cellular water frequency

61.0 Hz. Properties similar to those of intracellular fluid in the biological resonance range.

Taste

Soft, fresh, pleasant. Retains its pleasant tea-like flavour even when stale or warmed. Hardly any other method achieves this.

Electrical conductivity

420–500 µS/cm. Slightly elevated due to mineral ions, but remains at around one-fifth of the limit value.

The result: revitalised water of spring-water quality. Pure, rich in minerals and easily absorbed by your body.

Overview: All reduction values at a glance

How were the tests carried out? All the results are from so-called spiked tests. This means that defined quantities of pollutants were deliberately added to the source water prior to filtration. This allows for an exact measurement of the extent to which each substance is reduced by the filtration process. This method is standard scientific practice because normal tap water often contains too low a concentration of pollutants to reliably determine the actual filtration performance.

The results therefore show how the PiPrime performs under load, not just under ideal conditions.

At the same time, valuable minerals are preserved. The water is not merely filtered, but regenerated: it regains its natural, vibrant structure.

Eternity chemicals, and why long-term protection matters

PFAS enter the groundwater via industry, agriculture and household products, and remain there. Your body breaks them down only extremely slowly. That is why it is not enough to test for contaminants just once: what matters is that a filtration system provides reliable protection over a period of months. This is precisely what was demonstrated in an independent 12-month long-term study of the PiPrime.

Laborergebnis — Potsdamer Wasser- und Umweltlabor

None of the ten PFAS substances tested were detectable after filtration.

The accredited laboratory (DAkkS) tested for PFOA, PFOS, PFHxS, PFNA and six other compounds. Reduction rates exceeded 99.99% in each case. For a gravity-fed system such as the PiPrime, which processes several litres a day, this level of consistency is crucial. Not just when new, but throughout its entire service life.

The image is an informational diagram explaining the process of water purification, with details on the before and after stages of the treatment.

Six good reasons to choose the PiPrime K8

Proven to be clean

99.5% reduction in contaminants. Confirmed in an independent 12-month long-term study. The PiPrime reliably removes heavy metals, pesticides, PFAS, hormones, pharmaceutical residues and microplastics from your water.

Living water instead of dead filtrate

Unlike reverse osmosis systems, the PiPrime does not remove everything. Minerals are retained, and the natural structure of the water is restored using PI technology with 21 mineral ceramics. The result: water that your body can utilise to the full.

Self-sufficient: no electricity, no mains water supply

Simply place the PiPrime wherever you need it. No installation, no technician, no hassle. Ideal for the kitchen, office, surgery or waiting room.

Noticeably reduced limescale (K8)

No more white limescale on pots, taps or in the kettle. The K8 uses heterogeneous catalysis, a natural process that involves no chemicals. The minerals are preserved in the process.

Long-lasting filter modules

One filter set lasts a whole year. Ceramic filter (12 months), cartridge (8–12 months), limescale pads (every 4–8 weeks). All are easy to replace without the need for tools.

Sustainable and plastic-free

No more plastic bottles. Hand-blown glass bottles instead of plastic. Manufactured in the EU, using natural filter media. Around 12 cents per litre for spring-quality water.

For hard water

Say goodbye to limescale stains! Without losing any minerals.

Hard water leads to limescale build-up on pots, taps and in kettles. Many filters remove limescale, but in doing so they also remove valuable minerals such as calcium and magnesium. The PiPrime K8 takes a different approach.

The K8’s limescale filter pads use heterogeneous catalysis: a principle inspired by mussels and corals. Tiny seed crystals form and disappear, preventing limescale from settling on surfaces. The valuable minerals are retained in their entirety.

The result: soft, great-tasting water without limescale marks, yet still rich in minerals.

craftsmanship

Every glass container is unique

The PiPrime’s storage jar is hand-blown by experienced glassblowers in the Czech Republic. Each piece is crafted by hand, and each one is slightly different. This is not an industrial mass-produced item, but genuine craftsmanship that you can see and feel.

The subtle shade of blue isn’t just attractive; it serves a purpose: it protects your filtered water from exposure to light, thereby preserving its freshness.

Available as an option with an engraving of the ‘Flower of Life’ on the base of the container. A symbol of harmony and life energy.

Which PiPrime is right for your water?

The PiPrime is available in two versions, depending on the hardness of your tap water. The difference lies in the filter modules, not in the glass container.

Tested for twelve months. No loss of performance

Many filters are only tested when brand new. The PiPrime was tested under real-world conditions for a whole year, and the results speak for themselves.

Throughout the entire twelve-month test period, the MAUNAWAI filter system demonstrated consistently high removal efficiency for heavy metals, pesticides and other pollutants — without any measurable degradation of the filter media.

IIREC — Institute for Resonance Phenomena, Graz

This means that even after months of daily use, the PiPrime filters just as reliably as it did on the first day. We’d be happy to share the full study with you.

Frequently Asked Questions

The K8's calcium filter pads use heterogeneous catalysis, a principle inspired by mussels and corals. This process creates tiny "seed crystals" that bind to and release dissolved calcium. The result: calcium no longer deposits on surfaces, but the valuable minerals calcium and magnesium remain in your water.

The ceramic filter can be easily cleaned with a copper cloth to keep the pores open. Rinse the glass container occasionally with clean water or a vinegar solution. Optionally, you can naturally disinfect it using an Oxosanum tablet. Important: Do not place it in direct sunlight to prevent algae growth. In that case, use the PiPrime protective cover.

Yes! The PiPrime requires neither electricity nor a water connection. This makes it ideal for use in the office, in a waiting room, while camping, or anywhere you have access to tap water. The PiPrime also reliably filters lake and river water!

The filter modules are included in the initial package for the first year. Starting in the second year, the annual filters cost approximately EUR 130.00 (CHF 150.00). Based on an average consumption of three liters per day, your cost is about 12 cents per liter of spring-quality water. By comparison, high-quality mineral water costs between 50 cents and 1.50 per liter.

The ceramic filter lasts about 12 months, the Pi-Prime filter cartridge lasts 8–12 months, and the pre-filter pads are replaced every 4–8 weeks. A complete filter set for the first year is included in the package. Replacement is easy and requires no tools.

Reverse osmosis systems remove everything from the water, including valuable minerals. The result is “empty” water that your body has a hard time utilizing. The PiPrime works differently: It filters out contaminants while retaining natural minerals and revitalizes the water using PI technology. This gives you spring-water-quality water: vibrant, mineral-rich, and delicious. No electricity, no wastewater, no waste.

Yes! In a test conducted by the accredited Potsdam Water and Environment Laboratory, over 99.99% of all ten PFAS substances tested were removed; they were no longer detectable after filtration. This includes the four most critical compounds: PFOA, PFOS, PFHxS, and PFNA.

The PiPrime K8 / K2 provides comprehensive filtration: chlorine, heavy metals (lead, copper, mercury), pesticides, herbicides, pharmaceutical residues, hormones, PFAS (forever chemicals), microplastics, bacteria, sediment, and rust particles. It also significantly reduces limescale. At the same time, valuable minerals and trace elements are retained in the water.

The PiPrime K8 is the right choice if your tap water is hard—that is, 14 °dH (German hardness) or higher. This is the case in many regions of Germany, Austria, and Switzerland. The K8 significantly reduces limescale, preventing white deposits from forming on pots and faucets. Both models filter out contaminants equally effectively; the only difference lies in limescale filtration.

The PiPrime harnesses the natural force of gravity: You fill the upper container (4 liters) with tap water, and it flows through the filter modules into the lower glass container (8 liters). Along the way, it passes through a ceramic filter—which traps bacteria and particles—as well as the PI filter media, which contains 21 different types of mineral ceramics. With the K8, the calcium content is also noticeably reduced. No electricity, no chemicals, no water connection required.

Both are high-performance gravity-fed water filtration systems. The difference lies in your water hardness. The K2 is designed for regions with soft water, while the K8 is designed for hard water. The K8 cartridge features additional chemical-free limescale protection technology: Special ceramic granules prevent limescale buildup without stripping minerals from your water. Nature instead of chemicals—even when it comes to limescale protection.

Excellent. Our Kini reduces pesticides and herbicides to less than 5% of their original levels. Arsenic and copper are reduced to 12%, and uranium to 25%. With our larger systems, such as PiPrime or PiTec, the results are even better because they use more filter media. For you, this means your water is as clean as you want it to be.
