I will be using the water from the city.
At homepro they have 2 models for that kind of big filters, one for communal water and another one for the water coming from a well so I thought there was a point.
I would certainly not drink the water, it smells some chemicals just when opening it to shower.
And what about those small water filters that can be fitted in the kitchen for instance and that actually make the water drinkable? A nice thing to have?
I was thinking for coffee/cooking... it could be nice.
