Drinking water – is it really that boring?...
Many people think so, and we often hear that water has no taste and that it all tastes the same. When we say that, i

Our water is full of pesticides from agriculture and viruses from the ground, as it has not been purified before it reaches our taps. We have written an article about water’s journey from the ground to the tap, which gives you a more detailed insight into this.
Reverse osmosis is an older technology that was developed in the 1950s. The purpose of the technology is, unlike a carbon filter, to more or less eradicate all components in the water. This means that when the water has been treated in the system it "comes out on the other side" so pure that it does not actually contain anything other than its own molecules. Originally the idea was to extract drinking water from seawater, which to this day is still relevant.
We sell reverse osmosis systems both for the private household and for the industry.
If you wish to be self-sufficient in water rather than buying it through a waterworks, a private well is the way forward. The solution is cheaper,
