What happens to the water when many dissolved substances and minerals are reduced through very fine filtration? And what options are there for subsequently remineralizing the water?
Water is not just H₂O. Depending on its origin, natural water contains varying amounts of minerals and trace elements. It is precisely this composition that influences the hardness and taste of the water, among other things. The German Environment Agency, for instance, points out that drinking water can taste different depending on the region—partly due to the minerals that dissolve from the respective subsoil.
With certain water treatment processes, particularly with very fine membrane processes, minerals can be significantly reduced in addition to unwanted substances. This raises an interesting question:
Should filtered water be remineralized afterward?
💧 What does remineralization mean?
Remineralization refers to the targeted enrichment of previously filtered water with minerals.
The principle is simple:
Filtration → Reduction of unwanted substances → Remineralization
This allows the composition of the water to be specifically influenced after filtration.
This can be particularly interesting in cases of very extensive demineralization. The WHO points out that processes that largely remove minerals may subsequently require stabilization or conditioning of the water. Calcium and magnesium can also contribute to mineral intake.
👉 Why filtered water should be remineralized
🌿 Water as if from nature?
Natural spring and mineral water naturally contains minerals. Which ones and how many depends heavily on the respective source and the rock through which the water flows.
Natural mineral water is therefore characterized by its content of minerals, trace elements, and other components.
It is precisely this principle that serves as a model for remineralization:
Very finely filtered water is subsequently enriched again with selected minerals.
But what options are there for this?
🪸 1. Sango coral
One option for remineralization is the use of Sango coral or coral material containing calcium and magnesium.
According to the company, UrQuelle uses, among other things, a Sango cartridge for remineralization in its filter systems.
In this process, minerals are released into the filtered water.
Important: Claims about certain "vibrations," frequencies, or special health effects of Sango coral should not be equated with scientifically proven effects.
For water treatment, it is more interesting to know which minerals are actually released and in what concentration.
🪨 2. Maifan volcanic rock
Another option is Maifan stone.
This is naturally occurring rock that can release minerals into water. The exact composition and the degree of mineralization depend on the material, size, and contact time, among other factors.
UrQuelle states that it combines Maifan volcanic rock and Sango coral within the UrQuelle Diamant system.
The goal: The water should be enriched with selected minerals again after filtration.
💎 3. Remineralization cartridges
A particularly practical option is ready-made remineralization cartridges.
They are integrated into the filter system after the actual filtration process and release minerals into the water in a controlled manner.
The advantage:
You don't have to dose minerals or salts yourself for every glass of water.
However, it is worth taking a close look when choosing such a cartridge:
- What materials are used?
- Which minerals are released?
- Is there information regarding the composition?
- How long does the cartridge last?
- How is the mineralization controlled?
The more transparent the manufacturer's information, the better the solution can be evaluated.
🧂 4. Minerals, salts, and drops
Another option is the subsequent addition of minerals, for example in the form of mineral mixtures, salts, or drops.
This is generally uncomplicated.
However, the dosage is important. Depending on the product, even small amounts can significantly change the mineral content and also the taste of the water.
For daily use, a pre-manufactured remineralization cartridge can therefore be more practical.
💧 Why filtration and remineralization can be interesting together
Filtration and mineralization serve different tasks.
Filtration can serve to reduce certain unwanted substances and impurities.
Remineralization can then be used to reintroduce selected minerals into the water.
This is particularly interesting if a filter system works very extensively and thereby also reduces minerals.
It is important to note: Not every water must be automatically remineralized after filtration. The decisive factors are the process used, the quality of the raw water, and the composition of the treated water.
👉 Buying a water filter – what you should really pay attention to
💎 How does this work with the UrQuelle Diamant?
With the UrQuelle Diamant, various treatment stages are combined with one another.
According to UrQuelle, the treatment also includes remineralization with Sango coral and Maifan volcanic rock.
The system thus pursues a combined approach:
fine filtration + subsequent mineralization
For people who want to treat their tap water as comprehensively as possible and then remineralize it, this approach is interesting.

🌿 Mineralization is not the same as mineralization
When choosing, one should therefore not only pay attention to the fact that water is mineralized.
More interesting is:
What is it mineralized with?
The composition of the minerals used, the dosage, and the technical implementation can differ from system to system.
Anyone looking for a water filter with remineralization should therefore check the manufacturer's information carefully.
💧 Conclusion: Remineralize filtered water?
Very finely filtered water can lose a large part of its originally contained minerals. Subsequent remineralization can therefore be a way to specifically adjust the water composition again.
There are various approaches – from mineralization cartridges to mineral-containing rocks to mineral mixtures.
With the Diamant system, UrQuelle combines multi-stage filtration with subsequent remineralization using Sango coral and Maifan volcanic rock.
If you are interested in the topic of water treatment, it is worth looking not only at the filter performance but also at what happens to the water after filtration.
