Buying a tap water filter would probably be just as good as buying most bottled waters out there unless it's filtered by reverse osmosis or maybe distilled water.

The best filter you could buy for your home would be a reverse osmosis filter as it removes something like 99% of chemicals and stuff found in tap water. However, they are not as cheap as one you could buy and just stick on your water faucet. Unless you buy a revesre osmosis filtration system for your whole water supply (something like $1500) you're still going to get chemicals from simply bathing. I would love to have that, but I don't at this time.

Most bottled water like Aquafina, Dasani, Nestle is just tap water that has been filtered. Mountain Valley Spring Water is supposed to be a very good clean water though. I have a Brita water filter on my sink. I know there are better ones and I will get one as soon as I can.
