I have been drinking plain water of the same kind for fifteen years and doesn't need filtering of any kind
My wife and I consume through direct drinking as well as cooking and making ice for drinks
In total, we get through 100 litres per month between us that costs us B180, that is delivered to our door.
The taste is non-descript as I think it should be and proves to be entirely adequate for our hydration needs.
Yes, of course, we make coffee and tea every day as well.
I use tap water for shaving, washing hands and teeth brushing.
