Current system is three pre-filters and a salt brine flush softener that flushes itself every seven days. Before the pre-filters, we'd get pieces of shale in our tap water regularly. An under the sink system would have to be in addition to existing system. The other plumbing fixtures will foul within a year without the softener.

I am assuming you live in the south west, these systems are not marketed in my area. I can get water service, but it is much more expensive.
