Boiling won't get rid of much and it will concentrate things like fluoride....
Berkey filters are pretty good, and not expensive to run (gravity filter) once you start using it.
You could also buy a distiller, but that will not get rid of VOCS. Reverse Osmosis gets rid of a lot of things, but they are pricy to buy and run (filters and such)..
There is also water delivery/big bottled water from grocery store, which is usually RO water.. but they are in plastic containers, not bisphenol free..
