The Brita water filter is fantastic. From our hard water often I get a slight scratchy throat. The Brita water filter I can finally drink the clear gold from the tap and save a lot of money here, because I no longer have to carry home from shopping this insanely expensive and heavy six-packs.
The only downer is the decreasing water quality after some time. But you can also probably not have everything (especially since this is also the most wanted product world probably)
