Been doing this for years. Boil a gallon, let it cool, put it through charcoal filter. And my water is also hard so the boiling helps precipitate a lot of the minerals out. BTW Brita filter cartridges can be refilled if you drill a hole in the top, dump it out and replace with activated charcoal. This also saved my heart because when I got the minerals out, I stopped having angina.
