Dirk B.: Reducing TDS ppm seems to be possible only with reverse osmosis. I've been using an AcalaQuell One for a few days now because it uses PI technology. At least it has reduced the nitrate from 20 mg/L to 2 mg/L, the total hardness from 14 to 8 dH, and ppm from 335 to 190 ppm, although it has already risen to 230 ppm after a few days. I'd like to get below 80 ppm, but perhaps I'm overestimating this value. And I wanted to stop lugging around bottled water, even though I really like the parameters of the Plose water. I'm still not entirely convinced by reverse osmosis systems... too unnatural? The AquaVolta® Hydrogen Booster, on the other hand, interests me a lot, and its price is currently attractive compared to the Lourdes Generator.
TDS ppm (—> conductance) without knowing what you are lowering makes no sense. There is no reasonable target value, because 1 ppm of lead, arsenic, uranium or mercury is extremely dangerous, while 600 ppm of calcium and magnesium can make for super drinking water.
Plose water would not be approved as drinking water in many countries because it contains too few minerals. For example in Israel, where they are very strong —>Reverse osmosis Fortification with 50 mg/l calcium is required by law in order not to endanger the health of the population. Plose water only contains 2,3 mg/l calcium.
For real problem water, there is often no better option than a reverse osmosis system. But for good reasons I have never recommended a reverse osmosis system without a mineralization cartridge. I even recommend this when using a hydrogen booster, which theoretically also works with demineralized water. However, a good filter is usually enough, as described in this book on pages 19 – 21.
According to the tests presented by the manufacturer, the Acala Quelle water filter is also suitable for this. However, it is a stand filter where the water stands up, whereas with the Aquaphor Modern you always get freshly filtered water.
Reducing nitrate is definitely not a bad thing. But more important are the agricultural pollution that comes with the nitrate into the water. Some of them are not conductive at all, so they don't even appear as TDS ppm. A pure nitrate filter only creates a false sense of security.
In my opinion, the Lourdes hydrogen generator is overpriced because it cannot build up excess pressure to achieve high hydrogen values like a hydrogen booster. 1,2 ppm dH2 is the highest that comes out under favorable water conditions. However, the measured values that are presented on the Internet are usually completely wrong.
