My simple solution was to 'install' a ceramic candle type (Berkey is one brand) filter on a shelf just over the edge of our kitchen sink. Without moving it we fill it with tap water with the sink sprayer and only drink and cook with this water. As long as you remember to replace what you take out it is very low maintenance. After one year I have yet to replace a filter. Initial cost is a few hundred dollars, follow on cost is nil. You can filter out fluoride with one type of filter if this is a concern. It is also very resiliant in that you can use it with just about any water (think rain barrel, creek, pond) in an emergency.
