# PiPrime K8 > MAUNAWAI PiPrime K8 gravity filter with Flower of Life engraving. Ideal for medium to very hard water. Discover now. ## 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. ## 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. **Ceramic filter. The first line of defence.** **Lime filtration. Reduces lime and heavy metals.** **Activated carbon. The heart of the filtration process.** **Mineral ceramics. Just like in nature.** **Pi technology. Living water.** ## 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. **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. ## 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. ## How does the PiPrime compare? An honest comparison to help you make the right decision. ## 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. - **A noticeable reduction in limescale** - **Minerals are preserved** - **No more limescale marks** - **Natural principle** ## 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. > **Tip:** Not sure how hard your water is? Ask your water supplier or get in touch with us. We’ll be happy to help you choose. ## 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. ### Ready for soft water of spring-water quality? Whether for your family, your practice or your office: the PiPrime K8 delivers fresh, revitalising water every day, free from limescale. With absolutely no effort required. --- [https://www.maunawai.com/index.php/gb/en/p/buy/piprime-k8-gravity-filter](https://www.maunawai.com/index.php/gb/en/p/buy/piprime-k8-gravity-filter)
