Pure water is a pleasure and the building block of a healthier lifestyle. That is why a water filter is a basic element of every household and should not be missing under any circumstances. The good osmosis systems are very expensive. The cheaper ones do not have good filter properties. Our task is to offer an affordable system with very good filter properties. After 2 years of intensive research, we have finished building the H2O-Pur osmosis system. It was a great challenge to put together high-quality components with a limited budget that ultimately deliver a good result. We achieve a continuous filtration of more than 99% over several months (input: 200 PPM. Output: 1-2 PPM).
