Last year, one of my friends' parents were driving a decent way (around 12 hours) to spend a week in our area around 4th of July. They brought their 3 gallon Berkey with them. It was so big, I initially scoffed, like "That must have taken up so much room in the car!"
I very quickly understood why they brought it. That was the best damn water I have ever tasted. And I'm normally a big water person, straight from the tap for life, I mostly prefer water over other beverages, but this water... Idk, maybe they put some kind of undetectable addiction agent in their filters.
