Table water fountain

[Department]

I am looking for a technique to keep my table water cool and protected from light.
Currently I buy 5 liter bottled water, but I do not find it very practical and my goal is to use tap water that I have filtered.
I was thinking of using a stoneware jar, vinegar type, but is it safe and healthy.
If anyone can help me, thank you.

Bottled water is an ecological scandal ...

My wife (laboratory assistant in medical analysis) does not want me to store water ...
Except in summer, I don't keep it cool.

I had a filter carafe which I appreciated the quality of the water. I was able to measure the poor quality of tap water.
However, the filling of the filter carafe is very long (several minutes of waiting when it must be refilled in the middle of a meal) and above all its cost of use is high even if lower than that of bottled water.

So i opted for a fountain under sink less than € 35 (at bricobiiip) instead of € 100 everywhere else. The dual function cartridges were only € 4,5 the store stopped this brand and now offers fountains at € 100 with less good cartridges and at € 20
Apart from my problem to supply the same cartridges, I am very satisfied with this fountain.
