Your answer will rest my case (one way or the other).
I drink from filtered water for 2 reasons:
1. Filtering fluoride
2. Filtering any possible heavy metals out there
I would boil it too if I weren't so lazy to press a water boiling button.
Suit yourself really. I'm concerned mainly cause I don't want to end up brain damaged and then wonder what if I paid more attention to what I take in.
Not wanting to drink tap water because it squicks someone out, I can kind of understand. Kind of like how a lot of meat eaters don't like to think about where meat comes from. But when people (not pointing at you here, more a reference at past threads where this has been debated) insist that tap water is dangerous without being able to recognise that it's because that they have just been brought up to think that way, that's when things start getting really silly.
Personally, I think that the whole bottled water thing is an example of the power of marketing over sense. Heating water to 105 instead of 100 degrees like it makes any difference. Or in the West- fifteen years ago people used to consider tap water the preferred source, now people buy bottles of water that cost more than petrol. And we chew up huge amounts of energy in the treatment and transport (by ship and by road) of a commodity that is already frikken' piped into our houses and every building in the city.
