I was at a friend’s house once and he had one of those filters on his kitchen faucet. I actually got a glass of water from it and let me tell you it still tasted nasty. I can’t remember which one it was if it was a brita or culligan. I’m not sure. I always go and refill my 5 gallon bottle at a water dispenser. But I’m getting tired of doing it especially when the dispenser is out of order. So I now I keep hearing and reading that the sink water is fine to drink. Is there a filter out there that works well enough to be able to drink the water? Thanks
