Just filter your tap water. Then you can drink it from glass containers instead of plastic. I spent about $100/year on filters for my RO unit and it delivers bottled water quality drinking water at home.
Given the amount of variety of materials that water interacts with before it reaches your house and the fact that RO can remove the majority of organic and dissolved pollutants, it is probably still better to get a bit of plastics from the RO than the plethora of pollutants that are otherwise present. The benefits of this may vary widely based on the quality of the tap water.
Yea, we've got one. But when I lived in an apartment I wasn't allowed to install something like that, i'm gonna guess that most people aren't in a situation where they can use one.
I don't think there pitcher options that are as effective for fluoride or heavy-metals, but I don't actually know off hand
