Sink Water Filter

Sink water, filtered, or bottled water?
Which kind is the best for you? I've heard sink water has a bunch of gunk in it, but what kind of gunk?
What's wrong with regular bottled water?
I'm not asking what kind of water you drink, but what kind is the best, and why?
In all honesty, I feel like they're all comparable. Tap water is filtered and minerals are usually added before it comes out of your faucet. Adding a filter to your faucet just takes out some of whatever is there. A lot of bottled waters are actually tap water that is filtered. Now, the FDA is pushing to make it mandatory for all bottled water providers to list on their labels where exactly they get their water from for safety reasons because a lot of money is spent on bottled water but it's not always what we think it is.
