# Kini > MAUNAWAI Kini water filter jug: 100% made in Germany with 5-fold Pi technology. Filtration, information, optimisation and harmonisation. ## Do you know what's in your tap water? German tap water is considered to be well regulated—and that is true. But legal limits don’t tell the whole story. Pesticides, drug residues, hormones, and so-called “forever chemicals” (PFAS) may be present in concentrations that, while legally permitted, are unacceptable to many people. What’s more, on its way from the water treatment plant to your glass, the water passes through old pipes, household plumbing, and miles of piping systems. What is perfectly clean at the water treatment plant may look quite different when it comes out of your tap. **The good news is: You can change that—it’s easy, natural, and hassle-free.** ## Nature as our inspiration. Right in your own home! Imagine rainwater slowly seeping through layers of rock, sand, and minerals—and finally bubbling up as fresh spring water from a mountain spring. The Kini replicates this very natural process in your kitchen. - **Lime pre-filter**: The filter pad protects the main cartridge and reduces limescale and nitrate in your tap water. Valuable minerals such as calcium and magnesium are retained. - **High-tech activated carbon, shungite, and zeolite**: 170 grams of activated carbon granules made from coconut shells with a surface area of over 270,000 m². That is equivalent to 38 soccer fields. This enormous surface area reliably binds pollutants such as chlorine, pesticides, heavy metals, hormones, and medication residues. Supplemented by precious shungite, whose natural fullerenes act as catalysts, and zeolite, which specifically binds heavy metals and ammonium. - **Over 20 mineral ceramics (Pi technology)**: PI, tourmaline, EM, zeolite, and other ceramics regenerate your water. They restore the natural cluster structure and replenish the water with trace elements—just as nature does. > The result: water that tastes as fresh as if it came from a mountain spring. Lively, smooth, and easily absorbed by your body. ## Six good reasons to choose Kini - **Proven to be safe**: 99.5% reduction in contaminants — confirmed in an independent 3-month long-term test. Removes heavy metals (including uranium), pesticides, PFAS, hormones, and medication residues. - **Top-rated products compared**: In the independent Altroconsumo test (comparing 14 water filters), the Kini achieved the best overall performance against all contaminants without excessively softening the water. - **Living water instead of dead filtrate**: Unlike reverse osmosis systems, the Kini does not remove everything. Minerals are retained, and the natural structure of the water is restored through Pi technology. - **Quality of Medical Supplies**: The jug is made of SMMA N30, a specialty plastic typically used in medical technology. It is BPA-free, phenol-free, certified to ISO 10993 (biocompatibility), FDA-compliant, and tested in accordance with the strictest EU directive on food safety. Plus, it is 100% recyclable. - **A breeze to use**: Fill with water, wait a moment, enjoy. No electricity, no water connection, no installation required. Change the filter every 2–3 months—it takes just a few seconds. - **Good for you and the environment**: Produced in a carbon-neutral manner (Climate Partner). Recycled packaging. Replaces up to 3,000 PET bottles per year. No chemicals, no silver ions, no synthetic additives. ## PFAS — The Invisible Danger in Your Water Per- and polyfluoroalkyl substances (PFAS) are so-called “forever chemicals”: they hardly break down in the environment and accumulate in the human body. They have been regulated for the first time since the 2023 Drinking Water Ordinance took effect—but many water treatment plants are not yet able to remove them completely **The result:** — The MAUNAWAI filtration system removes over 99.99% of all tested PFAS substances. Confirmed by the accredited Potsdam Water and Environmental Laboratory (DAkkS). All ten substances tested—including PFOA, PFOS, PFHxS, and PFNA—were no longer detectable after filtration. Test report PWU, analysis number H2017-05556 ## The Kini Kanne Compared An honest comparison of the three most common filtering methods > The Kini offers the filtration performance of a professional system in a > compact pitcher. No installation required, and no compromise on water quality. ## What began as a solution to a family problem It all began with a child who suffered from atopic dermatitis: Mathias, the son of MAUNAWAI founder Maria Knoch. Doctors were unable to help, so Maria set out to find answers on her own. Her research led her to a holistic healthy lifestyle, water quality, and finally to Pi technology in Japan. In 1996, she brought the first PI water system to Germany. What began as a personal solution became a lifelong mission for the entire family. Today, her son Daniel runs the company, driven by the same conviction: Everyone deserves access to truly good water. MAUNAWAI is not a corporation. We are a family-owned business with nearly 30 years of experience, a small team, and a big mission. > Good water is not a luxury. It is a basic necessity. > — Daniel Knoch, Founder & CEO ### Ready for the best water? Try the Kini for 30 days—if you're not satisfied, you'll get a full refund.
