Drink charcoal filtered, reverse osmosis water and then try drinking tap water after that. It’s disgusting. Also, you can’t guarantee it’s purity, most public tap water contains small amounts of benzine and pharmaceuticals that governments say are below safe levels, that’s sub par to my standard.

I used to say the same thing and drank tap water, then I tried filtered water for a while and theres no way I can go back. Try it.
