> Do you buy bottled water from the store?

When driving. But not for day-to-day.

> Do you filter tap water? What filter do you use?

Yes. Brita. I don't know which one. It attaches directly to the faucet.

> Do you drink unfiltered tap water (which country)? Something else?

Yes. United States. I'm currently in Alabama and drink unfiltered tap water as needed. I also still drink straight from the hose outside when it is hot.
