Developed to make a difference. Impressive advantages.
The Fluid Dynamics technology of the AQON PURE system is the only limescale protection technology in the world that has been tested in an 18-month study on effectiveness.
AQON PURE is installed at the domestic water connection downstream of your water meter. As a rule, only a free pipe section of approx. 40–60 cm in length is required for this.
AQON PURE systems are completely maintenance-free during their service life. There are no costs for consumables, electricity or waste water.
The best thing about our one-year money-back guarantee? 97% of our customers never need it. In the unlikely event that you are not satisfied, you can return your AQON Pure system within 365 days without giving any reason.

Lime in water consists of the minerals calcium and magnesium. A classic water softener with salt (sodium chloride) removes these minerals from the water and exchanges them for sodium. As a result, the mineral content (lime content) of tap water decreases and the sodium content rises. It's actually a contradiction, isn't it? At the supermarket, we also make sure that we buy water that is rich in the natural minerals calcium and magnesium (lime) and: low in sodium. So anyone who has previously relied on a classic softening system with salt to reduce calcium deposits has worsened their drinking water quality.
AQON PURE therefore tackles your lime problem differently: Instead of removing the valuable minerals calcium and magnesium (lime) from the water, AQON PURE reduces the accumulation behavior of lime in water. Lime is present in drinking water in dissolved form as calcium (Ca2+) and carbonate ions (CO32-) before. When the water flows through AQON PURE, these ions touch the catalyst built into AQON PURE. The calcium and carbonate ions react on the catalytic surface and form small lime crystals (calcium carbonate CaCO3). The resulting lime crystals serve as an attachment point for the remaining calcium and carbonate ions in the water. Instead of forming calcium deposits on surfaces such as pipes, the lime reacts with itself. The advantage: The mineral content of the water (the water hardness) is not reduced. The entire reaction takes place without the addition of chemical substances, as the catalyst is not used up. Put simply: Your lime learns to swim, is therefore less deposited and is simply washed out every time you draw water. As a result, calcium deposits are effectively reduced.
AQON PURE supports progress in building technology towards environmentally friendly use of our resource water. Homeowners who choose AQON PURE are not only doing something good for themselves, but also for the environment. The differences in function between AQON PURE and conventional water softening with salt are therefore briefly summarized here. Because what many people don't know is that water softening systems with salt do not provide lime-free water. A so-called residual water hardness is always left in the water so that the water does not become corrosive. Even with a softening system with salt, a homeowner is not spared cleaning surfaces and descaling. However, both the conventional softening system with salt and AQON PURE make life with lime in your own four walls much more pleasant.
